not realy unless you exceed there max spec. the max operational is 1000mA but that will not burn them out. the problem comes in with heat. so if you up the current and don't provide an efficien way to remove the extra heat then yes the life will be shortened. If you deal with the heat then no effect.

I would personaly go with 1000mA for both as you are also using fuses and resistors to safe guard and dimable ballasts so the chances of you ever comming close to a situation where you would pump enough current/voltage to dammage the LEDs are going to be very very slim to none.

most people just run 1000mA dimable meanwells and nothing else and are not having problems. but I do like the idea of the fuses. not sure I like the parallel idea but I guess with the resistors you put to rest any concerns I have there.

The problem with a large build and not running parallel is that you would need a massive amount of the ELN-60-48 meanwells and they are not power factor corrected. As such, the In-rush current when/if you turned them all on at once has been considered dangerous for overheating the wiring at the receptacle.

Did you ever get a price and/or an expected delivery date on those HLG drivers? In looking on the cdiweb site, they all say "out of stock" and "call for pricing".

Power Supply:
well im not going with CDI because they wont ship anything but UPS and the guy seemed grumpy and he said 14weeks on everything

soo... i called meanwell, tried to find a distributer in Canada. I found one on the east coast which I emailed for prices. I also found one in cali that will ship via USPS if i ask nicely but they are about 30% more than CDI but cheaper than anyone else i found
http://wattsupply.com/s.nl/it.A/id.3056/.f

the girl was really nice and she said she would help me out if i need it USPS and could get it to for me in a couple days because her warehouse had a couple.
(i seem to have better luck with the girls than the guys)

so $114ish vs $85ish but no waiting 3 weeks.

Heatsinks:
ive also started hunting down heatsinks. for me to get the heatsinkusa heatsinks its something like $70 for shipping of all the heatsinks. They will do USPS for me though. Anyone know anywhere in Canada to pickup heatsinks?

Soldering Iron
I seem to be having a hard time finding a decent prized 40w-60w soldering station. Anyone have a lead on these? Seem to be expensive in Canada, lol. And I cant get amazon to ship them to Canada.

btw most of the other parts on my list are from digikey and they have warehouse in canada.

fyi parts list and wiring diagram updated

switching to 1.5fuses and bigger driver
added parts for grease, nylon screws, tap

Have you tried these guys for the soldering station?

I think they carry many of the ones that Amazon does.

Hope that helps.

thanks for the link, im probably just going to go with the 29.95 one that is 50w
i would like the 180 one but i think ill start small! lol i mean, all i need to do is solder a few leds... a few as in 144... cant be that hard or time consuming.

I ordered both my drivers through future electronics as well as my LEDs. They may be a bit more than the states but shipping was relativly inexpensive and the service was great

mseepman,
nice find on the soldering but im going to stick with the first one you found. dont really need the holder and glasses considering ill be soldering when all the stars are bolted to the heatsinks.

roblarss,
its a tough call. whats frustrating me is that cdiweb.com has them for half the price futureelectronics sells them for and $40 cheaper than wattsupply.com BUT cdiweb.com doesnt keep them in stock and the guy was rude. so i could take my chances with wattsupply out of the US and hope I dont get dinged at the border or use futureelectronics.... decisions decisions.

thats something like 20 LEDs i could buy if CDIweb had them.

did i just start using LEDs as monetary unit? WTF
