so in case of using the 2ok pot with 6 drivers does this mean that the lowest dim value will not be off? like if i use a 50k for 3 drivers? what dif does that make?

@Malocan very helpful but what does the N mean? and where did u get this file? ok i googled it got the file now i see the fine print so for 3 drivers id need a 33k pot?

@Growmau5 im looking at pots- I just need a 100k pot right? any specs to look for? single turn etc? also what if i want to connect 3 185 drivers to 1 pot? 300K pot?

hey i posted this a while back but here it is agian you can calculate heatsinks cooling by putting in its dimensions in cm there is also a ppfd calculator on the right fyi i would attatch cobs directly to the mars sinks and use aluminium angles to build a frame around it if i were you-adding...

wow a 14 cm COB??? anyways how can we determine the output of this beast? the data sheet seems to have holes ie they list ppfd but dont tell us what size space it is in(should we assume its in 1m2 and they ment ppf?) anyway why didnt they just make it run on ac and totally blow us away lol

on that note this one deserves a mention http://www.ebay.com.au/itm/131688162412?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 although on this ebay listing at least the specs are listed

looks like the LPC only works on 240V)ie not suitable for the usa) like the ELG also cheaper

lol keep in mind there are a lot of other sellers on alibaba with this part i think 75 usd is the going price jerry wants 73 ish

cool but how much? where do we buy?

great thanks beacuse i was looking at the data sheet for the HLG-40H-36 to drive 1 cxb3070 and it looked like it has adjustments for both current and volatge- i was hoping it would auto adjust the voltage which it seems u are saying it will? cheers

i dont really understand the data sheets for these type of drivers will they adjust the voltage to the cob or are they constant voltage?

what woudl be the point in using a 90 degree lens on a cob though?(vs the 115 with none) ok so i mean in like a tent ofcourse with a walk way it would be useful or when hanging from high ceilings

especially once u put 4 on a HLG-240H-C1750

alpine are rated to dissapte between 65 and 95w of heat depending on the model we run cobs at about 50w so around 20-30w of heat depending on cob/driver combo any of the cpu coolers will work fine- i use the arctic alpine 11 gt for 50w running the fan at 5v no worries others use the 11 plus- it...

ok cool becuse the xph50 is a slightly better deal although seen as u already have the driver its prob not gonna be cheaper(lumens per $) usually takes me 2 weeks to get stuff from them vs like 2-5 for aliexpress etc

oh wait u went ahead and built this? sweet did u get the chips yet? btw just call me dion, im usually over at icmag but the convo here allows me to learn as well

im using 4000k u2 bins and yeah i just have those on a separate driver to save lecky when i flip the big cobs come on (as well)
