Great Construction however, the 5/20/16 mfr date units have battery indicators that doesn't report the correct battery state.

After having charged to full capacity, the unit reads 3 Green Led Lights which signifies unit is between 70- 100% charged. Since it was pressed right after it was fully charged it would stand to reason that it would be at 100%. However, by turning on the light for only 2 seconds, the battery indicator then reported 2 out of 3 led lights ie, less than 69% charge left.

When the voltage of the battery was taken directly with a digital meter, the battery was still fully charged despite what the built in battery indicator stated.

Costco had these made with 4400 mah 3.7 volt batteries to keep the cost down. The manufacturer (E-Z Red) sells a very similar version that is totally encased in aluminum and with a 6600 mah battery pack that sells for about $83.00, #CT3515. Costco is not selling the CT3515 unit but a redesigned unit that is not all aluminum and the back is plastic.

Perhaps the battery indicator needs to see the 6600 mah battery to correctly read the state of the battery. Needless to say, the consumer will have no accurate way of knowing the condition of the battery.

I have a profound respect for the Costco Company and I hope that they will remedy this problem. If they don't, it truly will be a sad day to see that the good name of Costco would be tarnished over a $29.99 work light.

Hello @Costco Member, thank you for sharing your thoughts and experience with the Cat Rechargeable LED Work Light. I guess the manufacturer needs to make some improvements on these units. I've noticed that some manufacturers make certain "cheaper" models only to be sold at Costco and no where else. I know this to be true for some barbecue grills and it may be the case with this product. Costco is great and indeed has a lot of good deals, but they're definitely not perfect when it comes to some of their products that they sell.

Yes. My work cat work light 962841 does the same. Goes from 3 green led after a proper charge to 2 led status in a the few seconds needed to turn it on then off. That's pathetic not to mention the small scuff on the clear lens right out of the package. Not much difference between high 1100 and low 550 setting on my individual light. Non adjustable focus is okay but not great. I may return it if does not perform or meet my needs.

ExecMemberMike said...

Hello @Allen, that just sucks that the Cat Rechargeable LED Work Light just didn't live up to your expectation. It's a good thing Costco has a good return policy with products that you're not completely satisfied with. You shouldn't have too much trouble getting a refund if you do decide to return it.

How do you change to low beam and High. I push the on button on and off then on again but don't see any difference.

ExecMemberMike said...

Hi @Anonymous, that's just weird that you can't toggle between high and low beam. I wonder if the Cat Rechargeable LED Work Light that you have is stuck in either high mode or low mode. I assume it didn't come with instructions on how to operate.

ginofs said...

I bought this light at Costco recently, and came upon this discussion. My light was also dated 5/20/2016, and the battery level immediately drops from just turning it on. I was amazed how this thing lights up a whole room!

I read the accompanying manual, and it says the lamp switches from high to low on alternating on-off button presses: high-off-low-off. There is a marginal difference in brightness on low, but it seems to be dimmer.

Indeed, the battery level display may have been designed for a 6600 mAh battery, but I'm willing to see if the thing works well enough AS IS, ignoring the battery level gauge.

I find that the USB charging port shows up as a standard USB charger: 1.1 amps - not suitable for charging my iPad, but it's ok for smaller devices.

I would LOVE it If Costco came with a model that reads battery level correctly, and was willing to exchange units for people who have problems, but I just hope my unit performs decently enough as is to keep it.

ExecMemberMike said...

Hello @ginofs, thanks for sharing your experience with the Cat Rechargeable LED Work Light. That's quite impressive that the light can light up a whole room. It'd be great if the battery indicator level were accurate. Regardless, I do hope that it lasts you a long time though.

Unknown said...

to switch brightness only partially depress the on - off swtich.

ExecMemberMike said...

Thanks @Unknown for confirming out to toggle between the partial and full brightness for the Cat Rechargeable LED Work Light! Hopefully, this will clear up some confusion for those who didn't know.

ginofs said...

Re: Unknown's suggestion of partially depressing the on-off switch.
I tried very slowly pushing the on/off button, which is rubber covered. I found that nothing happens until the button clicks mechanically. Then the light comes on, either bright or dim. Pushing again until it clicks turns it off.

The on-off instructions in the manual that came with the CAT Worklight reads exactly as follows:
"The power switch has three settings: High (1100 lumens), low (550 lumens), and off.
Press the switch once for high, again for off. Press again for low, and one more time to turn it off.
The switch will cycle as follows: High-off-low-off."

I found that my light works as detailed in the above instructions. Perhaps Unknown has a slightly different model of this light that works with partial presses. The manufacturing date is stamped into the bottom edge of the frame (it's small type on black and is hard to read, but it's there). Mine was stamped 5/20/2016.

ExecMemberMike said...

Hi @ginofs, thank you for providing the verbiage for the high/low/off settings for the Cat Rechargeable LED Work Light from the user's manual. Yes, it's quite possible that @Unknown has a different yet very similar model that differs when switching between high/low/off settings.

I like my Cat Light. It's well built and very bright, nice size and sturdy feel. The swing out stand that doubles as a handle also works with the light on it's side, to stand at 90ยบ in smaller spaces.

As far as high/low, Mine works like both descriptions above, high-off-low-off as well as high-(tap to toggle low and high)-off. By tap, I mean push hard enough for the power to turn off, but not enough to click. This is a very nice feature, but I suspect it was not designed as one, so some switches might not turn off until after they click.

I wish the USB charge port would stick out sideways so I could plug in a cord and put it in a backpack without breaking the cord or port. Same for the power, but mostly for spots I'd like to mount some of these flush to a surface, but still have the option of unplugging and moving them around (think of sliding into slots in a work trailer).

One thing that is unacceptable to me, on low beam it makes a high pitch whine. As an electronic engineer, I know it could just be a bad capacitor in mine, so I'll be taking advantage of Costco's great return policy to "try again".

Thanks to this blog, I may even buy/acquire a larger batter and replace it (then the charge indicator may be perfect :) .

Also note, I'm middle aged, and my kids can hear high pitch whines that I cannot; I can definitely hear this whine, especially when I get close to it. My kids don't whine, my tools shouldn't either ;)

ExecMemberMike said...

Hi @Anonymous, thank you for sharing your experience with the Cat Rechargeable LED Work Light. I'm glad to hear that for the most part, it's working out for you. Hopefully, the high-pitched whine that you hear during the low setting is just an isolated incident for the Cat Rechargeable LED Work Light that you happened to get and not a pattern with all Cat Rechargeable LED Work Lights.

Hey, I bought this from, but lost the charger. Can you advise what is the output voltage from your charger? Assuming its around 5 volts which is USB standard but don't want to fry it. Thanks in advance.

ginofs said...

Jignesh:
I got all the information off my charger, and here's what its label says:
Charger for CAT LED Worklight:

AC-DC Adaptor Model RK-0421100
Input: 100-240 V 50/60 Hz 0.6 A
Output: 4.2V DC 1.1A
Center pin is +, outer shell is -
Charger has a LED indicator. RED = needs charging. I think it goes out when charged or turns green.

Plug is 5.45 mm outside diameter, inside ~2 mm.


Radio Shack has a $17.99 universal charger rated at 1 amp out with adjustable voltages of 3, 5, 6, 7.5, 9, 12 and 15 volts. It comes with a set of plugs for different devices.
The plugs can switch polarity so center is + or -.
Here's their specs:
Customizable to power your device using adapter plugs good backup or replacement power source for your device.

Compliant FCC, ETL. CA pro 65, DOE6
Input : 100-240V 50/60Hz
Switch power: 3, 5, 6, 7.5, 9, 12, 15V
Output: 1000mA
Lenght: 1.8m cord
Short circuit protection

So in your case, you'd use the 5 V setting. This ought to work, but since there is no charging indicator, you should keep charging below 8 hours.

Good luck!

ExecMemberMike said...

Thanks @ginofs for providing more information for the Cat Rechargeable LED Work Light. I'm sure many people will find this quite helpful.

Jignesh Jhaveri said...

@ginofs - Thank you very much for your detailed response! Much appreciated.

My unit's USB voltage is 3.9V, not enough to charge anything. The light is still a keeper though. Will be great for under the car when I need a wide beam light.

ExecMemberMike said...

Hi @Anonymous, ya the Cat Rechargeable LED Work Light can definitely be useful for the garage or any type of automotive work that needs to be done. Of all things, it makes for a great work light that is rugged.

Steve said...

Hi @Anonymous - Did you try pressing the white charge indicator light button for three seconds? My phone was telling me about the slow charge, then I read the instructions about pressing for three seconds. Now it's charging normally.

ExecMemberMike said...

Thanks @Steve for the tip on how to use the Cat Rechargeable LED Work Light!

Jignesh Jhaveri said...

I bought mine a month ago - so I would say yes.

ExecMemberMike said...

Hello @Ratana, I don't think the Cat Rechargeable LED Work Light is a seasonal product, so it should still be available at Costco.

Ratana Phan said...

which costco? no more in springfield costco. please direct me

Ratana Phan said...

ExecMemberMike said...

Hi @Ratana, I saw the Rechargeable LED Work Light from Caterpillar at the Costco in Redwood City, CA. Availability for this product will vary per warehouse location, so you'll have to check your nearby Costcos to see if they're still in stock. Hopefully one Costco will still have it even if your primary one is out of it. Good luck!

The Graphics Man said...

Hey guys, just jumped in here. Yeah just bought this light and had similar observations and concerns. A new question though, The paper manual says you should not charge this lamp with anything but the charger supplied or it could damage the lamp yet, in a comment earlier when someone lost their provided charger, a suggestion was to use a multi voltage one from Radio Shack (are there any still open?). Could I use a standard 5v charger?

Thanks, Graphicsman

ginofs said...

Graphicsman: if you're talking about a typical 5V changer like you'd use for an iPhone or Android phone, how do you propose to get from a USB connection to a round connector with female center connection? You would have to cut the end off the cable and find the correct size round female connector and solder the wires into the connector. That could work if you trust your ability to verify polarity and current being supplied to the CAT worklight.

Also, if you happen to have a 2.1 amp USB charger that would work with an iPad, you would be supplying double the currrent needed by the CAT worklight, which could overcharge and damage the worklight's batteries.

The Radio Shack charger I specified is really close to the original charger, and comes with a set of adapter plugs, one of which would work with the CAT light.

As far as being in business, Radio Shack closed many stores, but quite a few are still open. There are 3 still open near me. This was based on a successful business volume, as the manager explained to me. Also, RadioShack.com is still online. Besides that, you might find a similar universal charger elsewhere.

Unknown said...

Purchased one of these yesterday, with a manufacture date of 8/16. The battery is still the 4400mAh, and the battery level LEDs on the back are still not working properly. I'm definitely going to be looking into replacing the battery with a stronger one, if possible. But other than that, it seems pretty nice.

ExecMemberMike said...

Hello @Unknown, although the LED lights on the back of the Cat Rechargeable LED Work Light isn't working the way they're supposed to, I'm glad that for the most part, you like it and that it's working out well for you.

Anonymous said...

I just want to say that this has been an awful portable lamp -- the beam is way too focused and direct, and because the base doesn't accept a standard tripod screw mount, it's impossible to put it up anywhere where it would illuminate your work in a useful manner (like a regular shop light). On top of that, the fact that they went with a proprietary dc charger instead of a standard micro usb format is about an unbelievably bad design, especially as it takes 5v (since all lithium cells are ~3.6v and charge at 5v). I've tried to use this light time and again while working on my car, rebuilding a friend's computer, running cables in the attic, working in the basement, and it just fails to be useful in any situation, because the base just doesn't mount to anything where you could direct the narrow beam in a useful manner to cover your work.

Great idea, terrible execution. Go with a headlamp or Makita's 18v LED floodlight.

ExecMemberMike said...

Hello @Anonymous, thanks for your review of the Cat Rechargeable LED Work Light. I'm sure many people are having a lot of the same issues that you have in regards to this work light. Hopefully, the manufacturer will address these issues and will make improvements to subsequent work lights.

Anonymous said...

I bought mine about 3 months ago. Same as most others....except the ac adapter was only puttin out 3 volts. The light was only on 1 hour after charging. I charged wit a dc powers supply until three lights were green. Now they never go off and deplete the battery over night.
Oh yeah, the leds flicker
I am not going to take it apart. Just return it

ExecMemberMike said...

Hello @Jim, it looks as though your Cat Rechargeable LED Work Light has some issues just like the rest of those with this product. I'm sure it's not uncommon for Costco to see many of these Cat Rechargeable LED Work Lights being returned at their warehouse locations.

Unknown said...

Instead of purchasing the $18 adapter from Radio Shack, buy another light at Costco for an additional $12 bucks. Now you have 2 lights and the correct plug.

Unknown said...

The battery inside is indeed a 4400mah battery pack,supplied by 2 2200 mAh 18650 lithium ion batteries, the charger is 4.2v, and to turn it into a charger for your iPhone you must first hook your device to be charged to the USB port on the light,and then push the white button, the charger automatically turns off one you disconnect the device(phone etc)

ExecMemberMike said...

Hi @Unknown, thanks for confirming some of the specs in regards to the Cat Rechargeable LED Work Light and for the tip when charging a smartphone. I'm sure some people will find this useful.
