98% sure I read someone here say that Cree suggests iso alcohol to use on the COBs. Evaporates quickly and easily available. I used a cotton swab with alcohol to clean mine, no problems.
Thanks, so, problem solved

I suppose I would use clean, soft cotton or Kimwipes with water. Kimwipes are "Delicate Task Wipers"--paper tissues used in labs.

this one looks better than the round one!

Bonjour
I guess it is normally the emplacement of a fan.and the hole is to force air thru the hs...but it is more a vgacooler...
With the bigger if the fan fail no problem but with the small one I wouldn't bet on it...if you cool them very well you will keep them longer...yes you gonna run them low but with the price you paid for cob 10 or 20 $ more for cooling will bring you peace of mind (I know mine can't fry even at full power without fan at all...cxb@1400 release 22/24w of heat and I have very big hs but I add 120mm fan to be cold...not cool or warm...cold! to keep it a lifetime (10 year mini...lol!)

Bonjour
I guess it is not allowed anymore for public use since a year...they use it to print off-set but I asked a guy and he said no...I have to buy some on Internet!
I just wipe them sometime with a clean wipe!
What's angloinfo???
