Hello Everyone !
This is my first posting on any forum, Been reading thru past threads for a couple months now and decided to start a new thread didnt know if its proper to jump in on someone elses thread considering ill be around awhile hopefully lol ! So this will b my first grow & build, I decided on the eb strips mainly for the $ i have 10 eb gen2 560mm strips coupled with a hlg240h-c1050 driver. My plan is to use 1"×1/16 alum angle, Will this b sufficient enuff as a heatsink at 1050ma? I ask bcuz im reading different opinions on the heatsinking of these strips. If theres an issue ill get 1/8" angle,channel or 1" heatsinkusa, 80/20 1"×.05 which ever i can find the best deal on cuz i will need atleast 40ft to build 2 lights ! Thanks Everybody

That angle is more then enough for those strips.
Use a good thermal tape tho
I used 1x1 for the frame ends and 1x 1/2” for strips and it gets warm at most

Thank you guys for the quick response! Thats good news, the 1/16 is all i can source in this 1 horse town here in Nevada lol, yea that saves me a 2hr drive to homedepot in reno! Now i think ill splurge on the 80/20 for the frame ends so that just in case i have a brain fart & 4get how to add or measure the strips are easily removeable/adjustable. Also i do have a roll of blue 25mm × 30m thermal tape from amazon, was hoping that was the right stuff, Thanks for clarifying that i failed to ask earlier "Brain Fart" Damn it sucks getting old-er ! Thank goodness for this forum and its members for the knowledge & willingness to help greenhorns like myself, way kool ! hopefully in due time i can throw my 2 cents in and help someone! Peace

Oh and another thing when i purchased these strips i had to mix & match heinz 57 style due to inventory on hand, so each light was going to get 4-35k, 4-3k, 2-5k now i see there back in stock! should i replace the 5k with 3 or 35 k or does that make much of a difference? i also would like a dedicated seedling light like t5 but i thought just get more of the 5k strips with either a 80 or 120w driver! i suppose i can use the light im building now for seedlings just dim or raise it for the meantime, any suggestions ? Thanks

I wouldn't really be too concerned about 2 strips at 5K. I've used all types of BXEB strips, the differences were negligible in my experience. Some of my EB "lamps" are combinations of whatever I had spares. The 3000 vs the 3500 was basically unnoticeable over repeated attempts in a perpetual system.

I actually figured it out once for grins, on one of the bigger racks, and the average of the K values came in at something like 3270.

@Chip Green @torontoke Thanks for the help, Got the light built finally Yeaa ! One thing i cant wrap my head around though for future reference is the max voltage of the connectors on these eb gen2 strips 300v max correct? So if i wanted to say build one with a say 320w driver how do you calculate the voltage between the connectors and strips so not to exceed the max rating And would it be different between between cc / cv drivers ? Thanks

Ok so, the only time you would be exceeding 300V, would be with a larger CC model. For example.
Off the top of my head, a HLG-240H-C700A driver pushes 343V I believe, at a constant 700ma. This would be series wired, and not recommended, for multiple reasons, first being out of spec for the connectors.

Going down the CV road in parallel, the constant voltages we're working with are much lower, so no chance of overvolting the connector.
