if it were me. I would run the whole thing off of dc-dc drivers. i would purchase a meanwell ACDC power supply like: one of these pictured. ----------------------------- 1) I would calculated the voltage of all of my strings of leds. rough calculations: blue/UV string : 13.5+7+3+3 =...

foshizzle. interview with Mike from MammothP hear it for yourself http://dudegrows.com/mammothp/

I know you already ordered your stuff but keep forward voltage in mind when selecting your drive currents. eg. your blues 380-480 typically have a Fv of 3.5v @ 700ma = 2.45 watts per diode your reds 600-700 typically have a Fv of 2.3v @ 700ma = 1.61 watts per diode (but they can take up to...

DHL usually texts me week of delivery. Prompting me to go online and schedule a delivery time. I have gotten texts from drivers b4.

LEAVE AIRWALKER ALONE!

If it were me, and I was dead set on building this kind of light, I would go 40% xml2 3000k @1750ma 40% xml2 4000k @1750ma 20% Osram , Phillips deep red, or Cree 660nm and call it a day. @700ma I've had some nice results & experience with these diodes at these drive currents. That's just my...

I spent $200 on a Bluefish controller and wired up everything for effortless dimming and adjustment. I used it once to dim for a day or two, then set everything to 100% and never touched it again. moral of the story: dimming is like having two dicks. most people will rarely have a use for...

Transistor over heat & MW driver failure. Learned to keep the tops of drivers unobstructed "Free air convection " cooling doesn't mean no air convection cooling. Tried to dig further, but got annoyed, frustrated, bored.

1050ma for 61% with 3590 CD bin. it has taken me a while, but I have come to realize : for a personal garden of any decent size 100sqft ++ going 700ma to gain that extra 3% just isnt worth it for the majority of us paying 15 cents per KWH. Hawaii, Alaska, Guam, sure go 700ma. But I dont think...

I agree with Purplebuz. I would go Nextlight or Fluence- contact them for some jumper leads which allows remote mounting of the driver control bar. You will basically have a 1" thick light.

watts will always generate BTUs of heat. photons eventually become heat in a closed environment. 2000w of led in a bedroom grow op today will have same cooling requirements as 2000w of led next year. So for people in warm climates (like me) heat will always be the enemy. My greatest current...

3500k cxb spectrum isnt perfect, but its pretty damn good. I could see people rocking hlg240s or Pairui 250w to run 4 cxbs and one or two cutter cob to bump up that deep red range. once they come out. http://cutter.com.au/proddetail.php?prod=cut1851...

-if you take the extra time and angled aluminum to build a frame that has 2 or 3 parallel rails for holding these 107mm wide heatsinks, you can initially leave them loose. just pressed between the angled aluminum (no screws) -leave some slack in the wires between each cob so that you can slide...

very cool man! JorgeG's work with Citizens has really sparked a lot of interest around here. I am interested in them for myself as well,

I agree with @MrTwist1 the second option is what I would go with @wsntme . In a tent, your PPF at the perimeter will be much more uniform with a staggered config.

@JorgeGonzales is right, look at the world around you. - I got some fillings replaced, light used by the dentist to cure the ceramic, that's right Holmes : led - went 2 da strip club: illuminated booby tassels: uh huh, LEDs - abducted by aliens? What do you think they are using for anal...

@Airwalker16 hittem up for a free 60ml sample, lots of people on IG getting freebies. At 1ml per gal , it goes farther than a morman on prom night.

Whether you have led one or jumped on one, bandwagons have a way of running wild around here. Do we need to start considering Citizen cob's Fv in these driver talks.

Ok, I'll admit, I hit the GSC pretty hard tonight. But that aside, this is the funniest fckn comment I have read on here in a fortnight , would you mind if I borrowed that joke.?
