This is a pic of one of my first kits i sold. It is a 3KG 1000 x 100 x 100mm sqare tube with the drivers mounted inside and a 120mm fan at each end. I scrubed the whole surface inside and outside the tube with greasy paper, to have better heat transfer by a biger surface. For anti corrosion...

COOLMAC - LED - SYSTEM 300-1800W A*** efficiency up to 85 % -/ light-heat cogeneration / with integrated heat exchanger.

:peace::eyesmoke: This is *maybe* the most effective heat sink today. - easy to understand + copy Do you need hot water ? mount the chip and the driver you like... and take hot showers for free...enjoy my contents and criticise please (:

What does ICE stand for? :peace: http://www.acronymfinder.com/ICE.html ??? And yes - i already talked to the oceans...

:peace::mrgreen: No - why shouldn`t i believe in a self tested result, which is easy and simple to measure. Everybody can copy this test in 20 min. it`s not complicated - just do it. :fire::dunce::fire: You should be able to measure Vf, If, water temp. and water quantity. May be too simple for...

Yes - in a coolmac system the lamp = radiator and can be used during the winter night to bring heat back to the grow room. The condom is only a simple test to demonstrate the amout of produced heat and a confirmation for coolmac led systems and watercooling in general. Too many advantages for...

:bigjoint: just measured the heat of XTE royal blue - and i have bad news for you. :fire:Too much heat ! :idea::idea:Too much lumen/W ? I don`t know - but it`s hard to believe. I`m just confused. How can they(cree) believe in 619.7 lm/W ??????????????????? There must be something wrong on...

Mechanical Dimensions Figure 22: Drawing for Vero 29 LED Array Notes for Figure 22: 1. Drawings are not to scale. 2. Drawing dimensions are in millimeters. 3. Unless otherwise specified, tolerances are ± 0.10mm. 4. Mounting holes (4X) are for M3 screws. 5. Bridgelux recommends four tapped holes...

Hi brother :peace: my main interest was to proof the enormous heat production of led light. Because many people still believe that led light is the new tecnic with low heat production. That`s not true. :wall: @ttystikk @wietefras Finally this morning i found a statement of a prominent member...

:peace: it`s not plane - and a chip have 2 sides, where heat is emitted - not only at the bottom of the led platine. That`s why a condom or a latexballon is just perfect. Can`t believe ;) - are you virgin or roman catholic priest ? :bigjoint:

Hi man - just get the courage to wrap it in a waterfilled condom - not inside !!! - in between. I wonder that worlds great led companies are not able to seal a chip IP68 and hang it into water.

:peace: i guess you will have problems to proof that vero 29c is producing significant less heat than cree2530. - just take a "ballon" and measure your vero 29c @ even lower current as 163mA - you always will produce a lot (70% ~) of heat - even with led light. I see it like this: incandecent...

:peace::bigjoint:I think he`s a good man with an golden instinct - like me. You wanted to say more lumens, but you said less heat - so the winner is...........Yodaweed. If i do the same calculation for the measured cree2530 - I can run this chip @300mA(162lm/W) or @1600mA(93,6lm/W) light...

if you drive 10 cobs @ 10% of the typ. current, you have ~ the same heat production than 1 cob @ 100% typ. current. ~ The difference is more light output. To run a chip @ 10% current can easily double efficiency eg. 100lm / w ---> 200lm / w To emit the same amount of light you need only 5...

:peace: and how much is that ? :confused:

Yesterday i did a very strange, "exciting" test to know this a bit more accurate. I wired a Cree 2530/ 5000K/ T4 to a 10W @ 300mA led driver. I wanted to be shure to use a middle class quality chip and run it under low current efficiency. My wattmeter showed 10,9W / Vf = 32,4V @ 300mA. All...

2 x 120mm fans + carbon filter (6W / DIY) push out very few air. - I don`t have a heat problem.:weed:

:bigjoint: What ? confusion - Where ? :bigjoint: :peace:
