I chopped up a section of 400 x 40 sink with my old mashed up circ saw. just make sure you clamp the piece and clamp a straight edge to follow. and get hear defenders

Can you post a link to the mods pls. thanks dudes

Thanks Alesh, but to be honest I'm still not happy. (datahseet, not you :P ) there is a 70W difference in the first example AC120W DC 50W 85% efficient apprently... I don't understand.

the only difference is adding in a correction factor for the lagging PF on the AC side. Lets assume this is 0.9. That still means someones math is way off? e2a: I just looked at the recom racd100-700 datasheet and it takes 138W on the ac side and 108W on dc side. :S

THanks man, thats perfect. Good find :) HOWEVER :P SOmeone pls explain the 85% efficient ??

Anything suitable for 2 x cxb3070 @ 700mA ?

Does anyone know what the ND suffix is?

this thread is not for me.

Darth Vapour knows how to grow weed. the proof is in the pudding. @ Darth. LED potentially offers you a way to reduce your electricity overheads by 30%. However there will be a large upfront cost. Do a veg tent first, the savings will be noticeable. (we think) see how it goes?

You advise please Sirs. My box dimensions are 900 tall x 450 x 450 Lights are 4 x CXB3070 @ 0.7A. Should I use reflector? e2a: i know thats alot of light in that area, ~ 21W par / sq ft. - i probably dont need reflectors.

What are peoples thoughts on the 4.6" serrated profile for Passive Cooling 100W of led

600v tri rated cable. 05mm csa. best,,UKP

will this work?

hello, I am interested in this driver, its cheaper than a meanwell and it has a dimming 100W output (something meanwell dont seem to offer hlg or lpc) (for 4 x cxb3070 @700mA) Unfortunately it only offers dimming via PWM or 0-10V. Can anyone suggest a way of making a simple 1-10V dimming...

what about the 7% difference in efficiency/> i has the dumb?

I noticed a discrepency in data; Can anyone clarify? tyb

Kay but for the record, I was curious.

2 points; a) normal physics ? there is no such thing b) why you still no explain?

Quick explain? pls?
