I live in northren canada.. i could probably run a cob glued to a tile in the winter..gets down to -40C.

i just used pc coolers some good thermal paste and some thermo tape. the paste has basically glued the chips to the heat sinks. and they cost me like 9 bucks each

what about adding one to a heatsink? would it make any major difference?

also runs cooler than the other chips.

if you look at the lm/w the 1825 is the best at that amperage. so if you get me a 185-54 ill buy your 1825 light "engine".. i might swap out the fan for a Peltier cooler to it .. to experiment.

i could use a heater core from my pick up and a cpu water block....i don't live near many road signs..so maybe im way more of a redneck than you think.

put 3200 mah in the calc and look at the f/v on the 1825.. this is why i want the 185-54 over the 48...unless the 48 can handle 55 volts

your light is gonna get a plywoodboard. to sit in the middle of my 2 cxas on cpu coolers then im just gonna zap strap the drivers in a row and mount a clip fan above them for cooling... it'll look redneck as fuck. but it should be well isolated for shock.

6 clu058 1825's running at 3 amps each.. youll have bud for months. 3500K colour temp.

build a plug n play set up for people. charge cost plus 10% and cobs will be your day job. especially if you can get the capacity to build at a industrial rate.

i can get a cob with a cooler and a fan for less than I can a single chip from digikey. even with the bullshit shipping to canada all said an done its less expensive to order from cobkits than anywhere in canada

how do you recommend hanging your light engines?. i mean if all else fails im gonna make something with wood... but what is recommended?

anyone ever hear of em or use them?. my dad said he use to use them back in the day for overclocking. by adding them to the bottom of a cpu heat sink and then thermal pasting it to the cpu.. im just wondering if the same thing could apply to cobs. they seem to act like a cpu in so many ways.

nerd this for a bit then think adding a heat sink to the hot side. http://tetech.com/wp-content/uploads/2013/11/HP-199-1.4-0.8.pdf

anyone ever thought of using some old pc water blocks and maybe a heater core from a car.. especially on those 100V bastards..or... a Peltier module?

hmm what we do need is a good Canadian LED light maker that can import parts direct from the manufacture. for instance cobkits.com seems to have retarded low prices. and i think he might have connections with people close to the factory or a wholesaler that doesn't bend him over.. if I had the...

if you do order from the US. best thing to do is go with USPS it goes directly to crapida post and the brokerage/other import fees are not so bad. mostly just damn tax. and it depends on how the product is labeled

what about anything 185-54..dont care if its hlg hep what have you.. just so long as it can do 185W and 54V.. or slightly better

well im still gonna get a 3500K 90cri 1825..

i want to try to best imitate sunlight.yes my 3000K works but I think if i provide the plants with an even wider spectrum of light and perhaps even provide UV on top of that. the results of my end product should be better. I don't think people have learned everything about what spectrum of...
