lm/W is set by the single die on the COB, and in the Datasheet the Temperature is fixed (25°C / 85°C)

...from my naked eye i woud say the cree curve is above 4700 K

but it is!

only chilled coolers can stay or go below ambient temps.

Meanwell LDH-45 series can boost 12V up to 83V with 90% eff. http://www.meanwell-bg.com/files/Models/LDH-45-spec.pdf

ttystick is talking BS from a simple water-cooler (Tj 45°C) to a Water-chiller (Tj 5°C) we have an increase of about 7%. for this we need about more then 50W cooling power. numbers are based on 1 liter(1000 ccm) of cooling liquid

Ik denk dat je geen idee hebt waar ik woon Zweedse pas de tweede taal hier "Nyt olet Kaukana" is wat ik zou zeggen ------------------------------ and for the rest.... his try to blow up the typhon-code from 4 to 6 channels fails early in the declaration part .btw. the simplest part of the code...

we have rules for this...

wasted time... it´s just a bad copy of this http://www.bnkk.net/Typhon/Typhon.pde

my led... Yes Your led... I don't know

so it can also handle 450A / 1V and also 0.001A / 450000V have a nice day...

maybe the problem... Java uses point instead of comma for fractions 0.7 instead of 0,7

just a bit strange... Rayfiles are online, but no Datasheet for the new 120°
