Lighting Upgrading chinese LED

[Havok]

Ok everyone, i am trying to take this chinese growstar 150w LED and convert it to a COB.

When i check the power at the wall in its current state it pulls 64w.

So lets rip it apart and see whats going on.

Check out this high quality heatsink stuck to the back of the board. no type of thermal protective layer.

Stick a chip on the heatsink and glue the transformer to the back and suspend with wire, done! Cost £10/$15 for the citizen cl1212 3500k.

The output on that driver is teeny. 12v @ 800ma is like a phone charger or something close. Low voltage/amperage DC power is safe to play with, but there is no way to get more power. You could step the voltage up x3 to 36v but the current (Amps) is gonna get ÷3 as well. So 36v will totally light a 1212 but at 250 to 275ma or so, it's about 9 measely watts. I'm having a difficult time wrapping my head around that light you tore apart. 12v output at 800ma is 9.6w. Volts (12) x Amps (.8) = Watts (9.6w). That is smaller than the driver I use for my CPU fans. That would actually be a good part to donate to the fan cause. What light is that exactly so I can yell at the manufacturer for their lies. Walmart audio gear does the same thing...1000w subwoofer amp from Panaphony the size of a small book. NO WAY...lol. Then you see the real RMS of the product (Root Mean Square...which is average watts) and it's more like 150 or 200w. Get yourself a no name driver on eBay for $15 that is a 36v or 50v driver with the proper current flow (amps) to get the wattage you want to be at. Or go to Arrow.com and snag a Meanwell HLG for $60. The 240/1050 Meanie will light 3 or 4 fifty volt KAAAAHBS at a little more than 50w each. They work real good and u can dim them.

in all reality i will probably do that. i was bored and wanted to see what was inside this light. I can't run it in my tent right now. they make my tent to hot in the summer

yeah i am so confused. what was powering this thing?

10watts brother. Ya can't fake electrical stats. Volts x Amps = Watts. Every single time.

[Dr.Bubbles]

Look at the bright side...pun intended. Apparently that light is inefficient as well, if it's throwing a lot of heat on top of some light. What sorcery is at work to make all that for 10watts?? 15 years ago 10w would get u the equivalent of a candle...so at least there's that... Lol

oh for sure. not question that at all. this shit is silly.

i wish i knew about cobs before i wasted any money on these chinese lights

live and learn

 

[Dr.Bubbles]

...and then get KAAAAAAAAAAHBS
