anyone tried the makers led diy ?

saw this and if i can get some info it would be great
im really interested in this seeing how i can add build and place led where ever i feel i need them

looks like fun, have been thinking about it myself, but they seems a bit pricy, specially now that you have to make em yourself you would believe it would safe you money compared to buying a fixture, and I don't see many options of spectrum either, I customize my own fixture from a shop online and they build it for me as I like to have it

ya but if you order the pieces and not the kit it can be totally customized
whats the price of perfection
any help on the perfect spectrum would be really appreciated

from what ive heard 642 nm is the magic number

and look in there they have a catalog full of cree and lux leds
these are the top dogs ? arent they ?

yea I belive so, that Cree is the "mercedes" of LEDs also heard good stuff about royal blue, or atleast read about it before ?

about spectrum, 642 is in the Red spectrum nothing magic about it, its important for flowering, but its more then just one band of light, need a mix to hit all the necessary peaks,

the one I customized is for flowering and look like this:


120x3W (acctualy power 288W)

8x620
16x630
32x640
32x660
8x700 (infered)

8x455
16x 6500K cool white


but there are many opinions on this, its also a question of lenses the angle of em or if to use em at all and its also about how high you run your LEDs most Run 3W LEDs at 2 to 2,8W

plan on using the 1.5 foot fixture to suppliment my 400 watts of cfl
im running mixed spectrum at the moment and i strictly grow auto's so if i added 5-10 of these http://www.ledsupply.com/0b040-rdred-c.php on a 1.5' heat sink it would span almost my whole grow box is only 3.5' x 2.75' x 4.5' then i would be on par for budding ? my cfl's do ok just want to dense them buds up a bit the beauty of it is i can spread them out and slowly start to add more until my cfl's are side lighting and really no longer needed atleast im hoping

it says typically these run at like 8.8 volts i think im not sure how to read the charts

one thing I learned switching my HPS with LEDs is that intensity is almost the same (288W LEDs Vs 600W HPS) according to my light meter, around 5,000 foot candles at 2 ft distance,
and I believe par rating is much better with the LEDs, but the space the LEDs cover is way smaller, just a few inch`s out to the sides of the fixture my light meter drop a lot, so need to think creative, Im doing a scrog, and think of a fixture more or a light mover or both,

IMO "they" are right to claim that LEDs are as effective as HID, but that is right under them even tho they have to be +2 ft away and do penetreat nicely they don't really spread out the light much, I can cover about 1,5x2,5 ft now, before with my HPS it was more like 4x4 ft

thats what im getting at i can place the led clusters so they can land on a plant and not wasted space and for the area's i cant hit use the cfl's and just turn the plants like normal i turn them daily already seeing how im running different spectrum cfl's and like to keep it even
