Sounds like they wired parallel... meaning individual resistors per led... major wast of energy.

depends on how many led's per string... it's the string that goes out, not the whole panel

Pftt.... whatever... I can read buddy................. lol!! http://ledgrowlightsdirect.com/isis-fx1/

FX1 actually draws 170w... Draw is how much it uses, not outputs. And as for the 357 Magnum.. Getting 357w out of 180w? Impossible. That's the 2nd company I've seen pushing that crap. Panel may be 357w "full specs", but what are the led's actually set for? Using 100 3w Cree's...

Actually, that is pretty funny dude.. +++rep :D But, for those that don't know.. Spuzzum is like the smallest "shit.. I missed it" communities here in BC :D

People have used green incandescents in hid gardens for years, so don't see an issue with green led's either.

Here's the thing that really picks me about led "dealers".. misleading advertising. If you watch the videos for the 180w model, the guy brags about how they use Cree led's. But when you look at which spectrums are being used... Cree doesn't make 660nm, 730nm, or 380nm. They do make the Cree...

Well I must say.. THAT'S a freakin' heatsink!! VERY well done! Even has fuses I see.. well thought out. You should e-mail them back and mention about the thermal breaker idea.. similar to what's in your clothes dryer at home, or in a spot heater. That would definitely add a finishing touch of...

Here's a great thread/page that explains the sinks.. 1 guy even has a "thermal shut-off" in case the fans die. Actually a pretty good idea. ;) http://www.nano-reef.com/forums/index.php?showtopic=229786

Holy crap! I've seen you guys talk about the Kessil's, but that's the first I actually seen 'em! Niice. I like the light mover.. led's on a sun circle. :D Something tells me they ain't cheap either. :p

I believe the panel dunit's using has finned heatsink. The same thread showed the Blackstar with just the plain aluminum sheet. https://www.rollitup.org/grow-journals/386508-hempstar-3-stage-led-grow-7.html But as you say, the manufacturer has reduced the currents, so they'd run cooler for...

More expensive up front for the lights, but less money spent on fans, air-cooled hood/cool-tube, and less the cost of replacing hid bulbs once or twice a year. They say "10 years" for these panels, but the reef tank community says 5 years is more realistic. So even if you need to replace every 5...

They're my neighbours ;) Nice garden bro! Looking niiice. I see temps at 83.3F and ppm meter.. you using co2? What was the ambient temp before the lights? I'm thinking of co2 myself, using a 20oz paint gun cannister. I'm jealous, and can't wait 'til mine's built so I can play too! :D...

Yeah, there's rave's up here.. lol! What you looking for.. lsd??

Actually dude, the video was from a mod at thcfarmer... http://www.thcfarmer.com/forums/f8/theherbalizors-penetrator-345w-test-23349/ Yes, hid gives tight buds.. but if just hps, not as tight. Led doesn't make 'em stretch, so they remain tighter. Every journal I've come across, they've all...

Exactly! Ever walk through a forest or a park with tall trees? Here in Vancouver, in the middle of Stanley Park, in the middle of summer, at high noon.. you're pretty well shaded. And that's the sun.. not an led or hid. When these freshwater/saltwater tank forums such as reefcentral talk...

I got them from China.. http://stores.ebay.com/Louis-Electronic-Parts/Electronic-Components-/_i.html?_nkw=660nm&submit=Search&_fsub=2018248014&_sid=905094954 Cheap, but I couldn't justify $10 a pop for LedEngin's...

If you have any electronics experience at all, you won't fuck up your light just by opening it up. Warrantee is gone, but you won't fuck it up. There's absolutely no debate about it... these damn led's get hot! I just got my 660nm's today.. tested with batteries, and burned my damn finger...

Well, sales rep never returned my email.. But when looking at the Bridgelux site, there's a "buy on-line" link.. Digi-Key, Farnell, and Newark. Already know what Digi-Key has, and Farnell was by country.. so chose Newark...

I just emailed sales at Bridgelux and asked straight up.. "do you make coloured led's?" Will let you know as soon as they reply.
