I have built many QB rigs that cover 4x4s and 5x5s. The average cost is around 500.00 plus or minus. Check out my thread "From DEs to LEDs" it may help with some ideas..

Cheers,

my goal is to save power but dont wanna screw myself as currently im running dual hps bulbs would it make more sense to run 10 boards in 5 fixtures so i can have better efficiency over the 600w driver .... most likely i am gonna run 480w driver but im trying to think about my different options, and no i can't very well switch to a lower powered board as i already have them and i dont see that making alot of sense coming from a 2k setup

i see a kit that is listed at growerslights.com which is a kit version of the hlg 550 which uses the hlg 600-54b driver what are your guys thoughts on this over using the driver over the hlg 550 one (hlg 480 - 2100a) im looking into building 2 lights and using the lights over a 4x8 area honestly im am thinking i would be better off with the 480 but the differences in the cost of drivers is less the 100 dollars maybe i would be better off with more power .....

theres loads on alibaba same leds as quantum boards and some will be the same manufacture

your prob better running 200w ish drivers as there lots cheaper also if you went for vero29 s you would get more light for you money prob 6-8 of them to equal a 1000w hps

honestly i wish i had real boards as i feel like thats a pretty fair price and fair for everyone but the real boards are hard to come by and im trying to do things fast and for as cheap as i possibly can, i do own a hlg 550 tho lol ........ i figure im gonna end up around the 400 dollar mark for each light paid 400 for 8 boards so far

yes two boards per lamp using an hlg-240H driver.

Do you think theres much of an advantage with 312 pcb over 304 pcb if using 4 quantum boards to make hlg clone?

so ive looked into the specs on all three drivers and it seems like the 600w driver is 96 percent efficiency, the 480w driver has 95 percent efficiency and lastly the 240w driver runs at 93.5 percent so idk what to make of that obviously there is more then just the driver but i dont wanna screw myself over going for the 480w driver over the 600 if im not gonna lose out on efficiency as like i said im coming from dual 1k bulbs over my 4x8 area i do see that i can get 240w drivers for a few dollars cheaper and it makes sence if i am going to be doing 2 lights per heatsinks ...... idk

is it possible for me to get my hands on a slate 5 like whats used in the 600h kit from growerslights.com ?

from what i have gathered i feel like my best option is heatsinkusa, which was mentioned in the beginning of the tread figured i could get 4 26'' lengths for 170 or so ..... my first idea was a peice of sheet alumium and basicly copying the slate 5 heat sink both seem like they will cost a similar amount altho the heatsinkusa option does seem like a bit less work and honestly my hlg 550 gets smoking hot im sure the fins would help quite a bit id imagine i could add a cpu style fans as well which might be necessary if i go for the 600w driver

7.984 profile heat sink is the type that was suggested by nfhiggs, i like it just would like to hear a few more options if anyone has any input hear

That's interesting. Can you measure temp of heatsink right behind a diode ?

yes i will mesasure the temp tommarow when the light is on for sure but id say 120 plus as i can only touch it for a split second

The 8.000 profile is considerably more effective, with 1 inch fins, but its more than double the cost of the 7.984.

and yeah it does seem super expensive i haven't priced out anything but the first one u showed me which i would do 26 inch sections x 4 came out too about 170 with a 10 percent off coupon
