i just finished making a 400 watt led grow light fixture, i threw it together in an hour using mostly spare or hand-me-down items. My only problem is that....i really have no idea what the average running temperature of these Lohas 100 watt warm/cool white led's. I test ran the system and it all seems to work quite well but i feel as though im not cooling my led's enough. I used an aluminum rectangular telescopic dryer vent as my heatsink, i attached the led's directly to the face of it with copper thermal glue and self tapping screws, and i have a quite large duct fan sucking air through the system to cool it down. Oh yeah and i attached the OEM intake from my corvette to the exhaust end of the duct fan...you know, for that extra horsepower haha. Please comment on what i did wrong or what i could do to improve on my gawd awful design lol
I growing out of a small bomb shelter below my house!! It's an 14x8x9 room I am converting into two separate rooms!! Hey can anyone help me figure out my electrical!! My room is running off the same power as the back bed rooms and one bathroom!! I tested the power box last night to make sure!! I also ran a 600w a fan an intake fan and a 200w veg light off one outlet last night and everything worked fine and didn't blow a fuse!! I am wondering how I can see if I am close to blowing a fuse or how hard it would be to change where we run the power from? I am renting so I don't wanna do anything crazy!! Help me or let me know if you have any inside info!!
looks like I'm a bit late commenting on this one but, yeah I think that LED won't last long. those 100W chips just run too hot. I've burned them out using proper fan forced heatsinks on my experimental fittings in the past. when they eventually fail (if they havent already) just change to 20W chips. they run the same voltage and you just run 5 of them in parallel and space them as far apart as possible on your heat sink. here's a link to mine - it runs all 20W chips and delivers 1000W. http://forum.grasscity.com/gallery/image/162007-im...
depends which one of those breakers supplies your grow. if it's one of the 20s you can run about 2100w off it without it tripping. look at it this way, current = power divided by voltage so pick a breaker and multiply it's rating in amps by your voltage (110 in the USA) and that gives you the maximum amount of power you can run off it. allow a margin though, those breakers look old and might trip after a couple of hours at the maximum power you calculate. nothing worse than your lights going off and you not realizing till the next day. be conservative.
you are the fucking man..thanks so much...just took down some notes (becuase im too high lol) but im going to work on this, feeling optimistic. could b the weed lol
