    This chip bulb is amassing. This is what I wanted. All specs are in place. I used CPU heat sink and CPU heat paste.

    I bought the 110volt units, all 6 worked out of the box. I then connected a current probe to the incoming power connection. It showed a RMS value of 345mA (bottom of picture), not the 136mA on the BG site. BG should update the site info. No i was going to guess twice has high current (272mA) for 110V vs 220v, but its much higher, its not 30W, but 40W power consumption at 115Vac. This is good news, as probably 30W is the LED power. I used a 5"x4"x2" cpu cooler without fan and at 15 minutes it was 192F, I did not like this high temp (although the BG sight does not give specs on temp limits), so i will be looking for a larger heatsink. The LED is made up of 108 led's, and with three drivers (BP5132H), they drive the LED's in 36 series strings. Overall I am really impressed. I just need to dissipate the 40watts better, thanks BG!

    It's important no driver needed. COB lights are a more efficient energy.

    This is a perfect led module for it's price. You get a 30w white led with an integrated led driver on the module itself, saving you the cost of purchasing the necessary driver module. It is also great in the way that having a led with integrated driver allows you to design a much smaller light without having to accommodate a bulky driver. On the soldering side, when you will soldering the leads to the pads, you should find it easier to solder if you warm the bottom aluminum plate for a moment with a heat gun and then proceed to soldering the leads. I haven't tested the module for it's output power, but for my use it looks pretty decent. Hope this will help you.

    Strong light. It has no buffer capacitor, so it is blinking with the frequency of the main power. Be careful if you use it for lighting spinning devices (it has the stroboscope effect).
