I emailed you a large email on lighting earlier tonight. i have heard alot about leds, and they are getting better. but check that emal. its alot more cost effective, and i can garentee personaly that it works. i sent you my personal light details. interesting coincedence you post a thread aboy lights right after i sent that stuff lol. for how much you save on electimriciy, is led worth it? i recomended a plama as well, rundms at 300 w and produces light equivelabt to hid 600 w. and they are full spectrum all thru.
plus you cant change led bulbs. wgen they are toast, so is the system. ouch, expensive. hid systems last ong, as do plasma. they last much longer than thier bulbs. so in the end, yer always paying for something. leds arent perfect yet. hids and plasmas are as good as they will get. but they have been on the market much longer. leds produce no heat, and in my grow, i actually use my exess light heat to heat my room. i save on gas bill. you have to find ways to win with erry system.
check that email tho, its long, but i hope you look in that direction for lighting needs. btw, in veg, in my local, for 24-7 lighting, is about 40 bucks a month, per 1000 watter running. i have dimms, so it cots me less per light. i used to think leds are amazing, the concept of them, and the marketing makes em look perfect.i just havent seen enough evidence to make em worth it.
and a 900 w led will run ya like 2500 buck probably. i dont really know, as the small ones are so expensive, and i lack the interest to look at the big ones. i dont gamble, especially with 1000+ buck plus. i could probably build you a sick 3 light amazing organic garden for the price it would cost for one of those lights.
if anyone outthere is rock steady sure that these things work, tell us tho. i might go but a small ufo and try it on a plant. But if they are wrong, i will not hesitate to stand up and tell everyone what happend. that said, if they are worth a pinch, i woild be more than happy to inform erryone of a new miracle. but im wary, if they were a true miracle, they would take hids place as the standard grow light. thats not happened, so to me i think leds arent ready yet. im sure one day they will probably be the shit. if someone scaled up thosetiny bulbs, they would probably work better. remember, they produce light by conducting electricity across gas, and exciting the gas, simalar to how hids work, just different parts, and methods of opperation. lights with metal coils inside then are ineffecient and dont produce light spectrums biy simply changing gases and stuff.
no matter what you choose, look at all aspect, cost, reusability(resale value if you upgrade?) theres so many things i could write a whole page on lights, and points to consider. its something you have to look at your situation and what works the best.
