Super Bright 24 LED Camping Light. White Color, With Hanging Hook, Diameter 5-1/2-Inch, Middle Hole Diameter 1-1/2-Inch, Requires 4AA Batteries (Batteries Not Included).
With so many on offer these days, it is great to have a name you can trust. This item is certainly that and will be a perfect buy. The distributor have added some great touches and this equals great value.
You can trust this review, i hope you can try to buy this product and then you know this product good or no. Next time you can make a review for another people.
Modification...
There were reports of a potential fire hazard on this and similar lights... whether this actually posed a fire hazard or not remains to be seen, but the currant limiting resistor did get very VERY hot. The design of the light electrically is very basic and the quality of the soldering inside is very poor. The LED's are all linked in parallel, with one large 2.2 ohm resistor connected in series to limit the current. The stats are these:
6V supply (4*1.5V cells)
2.2 Ohm resistor
LED voltage drop 3.3V
-> 2.7v voltage drop on resistor
-> 1.2A current!
= 3.2 Watts dissipated (wasted) through resistor
This really is no good at all so I changed the internals ever-so-slightly...
Where the power connects the the LED PCB, remove the cross-links (actually the legs of one of the LEDs) so the boards are not connected to each other at that point.
At the opposite end connect the bottom left track to the top right and remove the other cross-link.

Bright, Cheap, but Easily Destroyed
I bought a pair of these to hang over my desk where I work as it is a little darker than I was used to. One of them came to me with the leads connecting the power switch to the batteries that I had to solder back together. The mechanism to lock the bottom and top was flaky at best. One fell onto my desk when I shut it off, sending batteries and battery holders flying, rendering that lamp useless. The other one followed suit about 4 days later.
Pros:
- Cheap and bright
Cons:
- Not so good construction, locking mechanism was hit or miss
Other Thoughts:
- I got 24 super bright LEDs for my project...
FIRE HAZARD
First off this WOULD be a great light.. I've had one for a while and hadn't noticed a problem with it, thought they were great little light sources, so I bought two more. Put batteries in them and turned them on. One of them came on for about 5 seconds and went back off. I opened it back up to check it out and make sure there wasn't a broken wire of bad solder joint. I didn't notice anything right off so I turned it back on and it started smoking. The reisitor inside was laying on one of the wires and had lead on the end of the resistor had got hot enough that it melted the insulation on the wire and caused it to short out. I seperated the two leads and the light came back on, but the resisitor was still hot enough that it was smoking and scourching the plastic to a burnt brown.
I thought maybe it was a quirk with this one and that the resisitor as perhaps the wrong, but when I opened up the other two lights they also show signs of the resistor heating up enough to...
