ah see I just make and use and then build my next light
saying that the 1st 100w cob I built is still working had to change the driver as I made it with an old driver I had from another light I had to repair saying that it ran for 6 months or longer with no issues then fired right up again when I changed the driver
Thermal grease, an old cpu heat skin and fan.. oh and a plastic tub the delivered my take away food in with some cable ties
I`d ordered thermal grease instead of thermal cement, actually the grease alone is sticky enough to keep the 100w chip attached to the heatsink and taking it off is really easy but I like thermal cement better as I do worry about the chips falling off if you just thermal grease and nothing else to hold them in place
Yeah makes a really nice light in my workshop, think it`s days of vegging 1m plants are over but not like making a new one is hard
still nice to see something you made ages ago still works and puts out good light always encourages you to make your own again next time
