Really good light module. 3 of them are sufficient for 17m2 room. Good antistatic packaging. Leads are gold-plated: soldered with ease. Due to small size and high power MUST be used with heatsink (temperature of module must be less than 80C, if you don't want to shorten it's lifetime noticeably) Color temperature is close to daylight, this is acceptable ...

Very bright light from this, heats up instantly without a heat sink so there are some wattage giong through this. Good thing its mounted to a metal plate with screw holes so its easy to heatsink it. Solder tabs are easy to attach wiring to and are clearly marked positive/negative. Very soft coating on the leds, I can press my finger on it and see my ... Read more
Very bright, much more brighter than other strips I have measured at the power of 5W.
I am using it at the power of 5W, it is still very bright but it does not produce so much heat. At the full power of 10W it can be compared with classic 40W bulb.
I ordered more and plan to replace classic bulbs with these LEDs. Two per room should be enough None As ... Read more
cheap, bright, does not heat much. However you need *some* heatsink, otherwise high temperature will destroy LED none. However it would be nice if price would be a bit lower. I would also appreciate if I would find similar element with power ~15 Watt the light is too cold. Colder then white CFL. But it's OK if you like that flavor You need to find 1... Read more
This LED module just produces an extreme amount of light! It work's very well with the DC-DC Automatic Buck-Boost Constant Voltage Constant Current Module to regulate a constant power flow.
Use a good colling block, at full power these babies produce some heat. No cons found, the light output is just overwelming! Very good for DIY projects, but do not ... Read more
looks very well, it's exactly like seems in the picture.
The case is aluminum and the COB LED. Not ready to use. You need to weld the cables on it, but it's easy to do. The dimension of this they is small, bright a lot if you don't use a resistor. They works at 11V and the light it' ok ( for a desktop lamp ) and they it's cold ( you can touch with your ... Read more
so much light, so so so shiny, you can be blind, you can think that you can use one of these in a room on evening instead of regular ceiling lamp. so much light means so much heat and so much heat means very short life for these leds. you have to use it with extra heat resistance otherwise inner small leds in the COB led can easly get burned one by ...

Well packed, good quality, was what I expected, good information. Really give much light. Due to its thickness is possible uses them in very narrow areas. As has been written should be careful welding, must use an iron with high temperature so that the welding is done as fast as possible. I'll probably re-order the product again. A good choice for those ... Read more
Very bright! Compact design
Terminals marked well
Easy to use ... Put power on it and it goes! Solder pads may be a bit small for someone that is not too handy with a soldering iron! Apart from that, there is nothing wrong with this light! Be aware that it does produce a bit of heat so will need to be mounted to something that can handle the temperature.... Read more
Very bright Good opening angle. Very thin (can also be a con because of bad dissipation
comes with a silicone surface to difuse the light and protect the leds.
already has holes to help fixing it its own dissipator cannot handle half of nominal power, but not a real con if you want to limit the size with 12 V I've limited the current with a 4,7 ohm ... Read more
