COB LED flashlights? discuss, point, recommend, criticize ....

A lot of “COB LED” flashlights are showing up.
Here’s one of many, the page shows you dozens of other kinds.

Anyone know anything about them?

Sources for the COB emitters, for modding/improving?

Hmm link does not work
Please use the button (fifth from left on quick reply ) and a word, sometimes it does work then (so we see a click able word instead of link)

I paid $5 from AMZ review Trader.

I like it, its neat and fairly bright. Not a warm tint but nor bluish.

Had to order one just to see. Also order this one that has 20 and 3 emitters:

If they are anything like this one, I will be happy. This light is by far my favorite light to use under the car, hood, dash type work. Pure even flood with nice tint and no throw.

I bought mine at gearbest, its a cobi lil larry clone. I ordered it a week ago so i cant say anything about it but its cheap, you cant go wrong i guess. I guess its a very cold color temp but who cares for that price. This one is aluminium, they also have a plastic one for nearly the same price.

I actually picked up a few of these in various sizes & tints recently, but haven’t had a chance to play with them yet. Seems like bare emitters are mostly 12v, at least from what I saw at BG.

One example:

I love the one I have and I would recommend it for anyone. It would be great for work, where you wanted to always have a light that could stick to metal objects and gave enough light for close up. It's an even spread of light and I really like it. I also keep one for the car as well. Great because of the magnet.

I don't remember the brand name. It is yellow bodied and came out of Amazon. One of the most popular ones.

 

EDIT: Cliplight was the brand and it was on Amazon.

I have the Larry 2. The future Mother In Law knows I’m a flashlight geek, so I got it for a present. In all honesty, it’s really not bad, and very practical I suppose. I think anyone who is not a member of this forum would be impressed, and even for us, it is somewhat useful. Of course I worded my thank you much more eloquently. As future Mother In Laws go, I know I could do much worse.

I bought one of the red cob pen light for under $5AUD from Gearbest a couple of months ago and love it for what it is

It’s on shed and for under the hood duties

Close range only – all flood

Strong magnet too

I saw the same light for $15 at an auto shop here (someone else shops at GB !)

Oh We're From Tigerland.....YELLOW AND BLACK!!!

I linked the same light at gearbest above, maybe you prefer gearbest.

Those NEBo Larry lights are expensive here in germany, thats why i ordered a clone. Cant believe that some of you bought those NEBO lights for 5 dollars, damn.

Thanks, nothing beats the dispute system of AliExpress and its even cheaper so I ordered there.
For another topic I was looking at Amazon.de bur yeah all is much more expensive there.
Amazon is like a last resort (for example ordered super lube there)

Came across those COB work lights on GB a few months ago. I am an automotive enthusiast a have many friends in the repair business. Been giving them (Plastic version) away to buddies and family. Got a few Aluminum ones for myself. So far only one casualty, where it got too hot and melted the lens on a plastic version. Buddy asked whats the waranty? I said I would give him a full refund on his free light. He is 5hour drive from me but I will get him another one on my next visit in a couple weeks.

Snap-on sells a similar light for $30, large auto parts chain sells the same $3 light for $15 around here. Another friend said his paint supplier sells them for $9.

Oh yeah I did have a couple tail magnets come out but CA glue took care of that. I run Eneloops in mine and found one left on inside my backpack. Found it Sunday morning & had not moved the pack since Friday. It was still lit after 2+ days. Not Bright but Lit.

Very practical work light for it’s size. Worth the $3

I have a couple. I keep one in each car.

I agree with Bikenbeer on the tint. It is a handy light to have in the car in the event that I need it.

For what they are, they are very handy. My wife got a couple about a year ago and they have held up very well!

I have a Nebo Boig Magnum Larry I saw at my local Ace hardware but ordered on Amazon. Great work light. Super strong magnet and wide, smooth, floody beam. Rated at 450 lumens and looks at least that bright to the naked eye. My only complaints are the UI (must click through all modes to off) and visible PWM in the lower mode but under the hood its not an issue. I would like to see a good low mode on it for extended emergency lighting.

I saw some that run on 4 x AAA batteries. Anyone have these? Are they brighter or do they run longer?

I have a friend who is a Heating and A/C tech. He said he and the guys he works with all use a light like this for their work. He likes that it will shine into a small space and light it up evenly, without being too bright. He also likes that he can clip it onto the outside of his shirt pocket, so it will light up a small area directly in front of him for working. I tried to give him something brighter and he said it was too bright for the small spaces he works on. My contest light this year is (very loosely) inspired by this style light. But, it won’t be nearly as shirt-pocket friendly.

I have several of these from NEBO and a West Marine branded one. Pretty neat, handy little lights.

In answer to the OP’s questions……..
I did a quick search and THIS PLACE has COB Emitters for sale.

Here is a link to a search for COB EMITTERS .

I got a bunch of the NEBO COB Lights HERE at LIGHT JUNCTION a while back when they were having a super sale.
40 – 50% off best I remember. Smile
Got several for me and a bunch for gifts. I just find they are handy little lights to have laying around. Thumbs Up …. I run em’ on Eneloops of course. Wink

> search … link

On a quick scan, those look to be 12-volt COBs, and I don’t know any drivers appropriate to that voltage for handheld lights.

Does anyone have a pointer to the COBs and drivers that are being used for the small flashlights?

Any takeaparts?

I searched for “5v COB” and found these little 4.5v, E10 screw-type lamps (but high to very high minimum quantity order)

I received my cob lights (from the link in the OP and in Post 5). They are both nice, but I really like the pen light from the OP. It’s better than I expected. The aluminum body is thick and seems strong. I’m impressed with the amount of light this baby puts out. Very even wide flood as expected. The tint and color rendition is great. The light spreads out so wide and evenly, that you don’t have to worry about glare (Like DavidEF’s friends have said).

The magnet on the clip is fairly strong. The tail magnet is pretty weak. I can really see keeping a few of these in my car. Engine problem at night. Stick one on each side of the hood (by the clip magnets) and you got your self a nicely engine bay.

Don’t know what the run time is like yet. Seems like it may not be long with so much output. Will try to see how hot it gets and how long it runs tonight.

I guess this vendor is selling them at such a low price due to the logo. These go for much more everywhere else I have looked. I had a problem with a third item I purchased (not a light). It was the manufacturers fault. The vendor straighten out the matter on the spot for me with just one private message from me. So I ordered 8 more of these pen lights. Some to keep in my cars and a few for my parents who I know will really like them.

Thanks for this thread hank. I will probably pull one apart when I get the next order, but I doubt I mod it. Might put in more powerful tail magnet. Actually, wouldn’t mind a few modes.

EDIT: Added more content.

I have the pile of these in plastic and aluminum. got a couple more red aluminum in the other day.

Got a pic of the tail magnet? I think it may be in backward. I do not think any of mine are weak on the tail magnet. and I think in comparison the clip magnet is weak to the tail. Tail magnet has a steel surround or a cup. You should be able to see the steel ring around the edges. If not I would say it’s in backward.

Had important things to be doing so I skipped all that and did this. I will be keeping this one. UMMM, its definitely Brighter.


If you need to get one of these apart just get a fingernail between the side of the lens and aluminum and pop it out. Rest will easily follow. Don’t forget the rubber cap on the SW. You will have to take it apart AGAIN.

Appears mine is backwards then. Thanks for the tip. Also, thanks for the tip on how to break down the light.

So, it appears that the LED has no real heatsink path to the body. Unless there is hidden circuitry in the switch (doubtful), the emitter is direct drive with 1.5 ohm resistor bank in series. There are plenty connections and thin wires that add to the resistance. Hmmm, getting some moddy ideas.

EDIT: Sorry for the multiple edits. Had trouble getting my response out of the quote.
