maybe email coralux and see if they have any boards for smd drivers they did for me and left resistors off the boards since i wanted full on and off by power not controller

SMD is surface mount component if you had the bare pcb made that is the component you have soldered onto the board instead of holes its pads

the hs is SMD style you will have good luck with them i just looked the driver up

I missed the hs and just used the h but i would look at the data sheet and see if it would work you are only using 9 pins and if they are in the right position then its a bonus the issue would be if the pin out is different then you would have to solder wire to the pins

you will need to put these on a board like the coralux they make them in 2-6 ldd boards http://coralux.net/?wpsc-product=ldd-6-driver-board the drivers will line up with the holes on the board now you will need a power source and a controller like the storm or arduino I used one for the far reds...

You know the cob you want to use the data sheet will tell you the min and max voltage also the amperage it can run now you want to run them at 1.4A time to do the math

The driver I would suggest is the EGL-240-54 now choose a model dimming or not or smart dimming they are $10 cheaper per driver over the hlg but can only run them on 240v also to run 15 cobs total you would need 5 drivers or go with a bigger driver. elg-240-54 puts out 4.5A / 3 = 1.5A each cob...

its a decent light but you will also need 6k btu of cooling for hanging that light. I ran 4 gavita before and they are heaters. slow down because one min your thinking of putting 1000w open hood and then ask about 5 cobs that will not cover the same area. ITs not knowing what your goals are...

Well a decent 1000 w digital ballast is going to run you $200-250 A hood another $150 and a bulb is $100 say a even $500 Now for $100 more your into cob leds and its more efficient plus your saving on the electricity. I switched over to cobs in my flower room and with the hps I needed 70A just...

It really depends if you are using solid core or stranded wire http://www.engineeringtoolbox.com/wire-gauges-d_419.html 50A you can use 6ga wire or solid 10ga

neither 3 600 watt but if it was me i would look at cob leds

18 ga solid core can handle up to 9.5A http://www.engineeringtoolbox.com/wire-gauges-d_419.html

When they were running in the garden they were great but they have been replaced with cob leds

personally I like http://solis-tek.com/products/digital-ballasts/solistek-matrix-se-de-1000w-digital-ballast-120-240v.html the built in timer is nice and one remote will control more than one ballast if you have them

according to the pic the mains is on the sides it doesnt reference a difference in wich side is for hot

it worrrys me when you say neutral here is why it doesnt carry a current and 2 pole breakers have current on both poles of the breaker edit = line and hot will let people know a 2 pole 220v breaker is needed

no it doesnt they both will carry 110v from the 2 pole breaker I was that you were in EU from the product page you linked. I run my ballast here in the usa on 220

Its 220/240v so you have a line a hot and a ground edit= the 2 green in the middle is the ground on each side a wire goes to each pole of the breaker

This is what I used to run 70A out to my detached garage http://www.homedepot.com/p/Southwire-By-the-Foot-6-4-600-Volt-Black-Stranded-CU-SOOW-Cord-55809199/204725137 A friend that is an electrician just rented a trench digger and put that cable inside a pvc pipe and buried it

Since you have a height restriction I would look into the quantum boards even the citizen and luminus are more efficient and cheaper than the crees If you used citizen 1818 and had 70 of them in there and drove them at 1.4A your ppdf would be 1515 Edit= if you dirve them at 2.1A 65 would be...
