You are going in a direction (series) which is inherently more dangerous.
You have other options as well, like parallel and series parallel.
(Lets say you want to drive 10 strips as an example.)
Parallel is typically safer as the DC voltage is much lower. In this case you would need
a high current/low voltage driver. Current demands would be (10x .7A ) or 7 amps and 20VDC so maybe a HLG-150H-20 (10-20V), 7.5A, 150W
options can be few or maybe it is out of stock… so
Series/parallel. Could be 2 in series and then all (5) of those pairs in parallel. So then we need 40VDC and 3.5 A. so maybe a HLG-150H-42 (21-42V), 3.6A
Neither of those two options will make you to do a backwards somersault from the squat position.
current kills, voltage is potential energy.
But either way, it only takes 150 mA to cause respiratory arrest. I highly suggest grounding your light fixtures. The simplest way to do this is to have the driver case directly touching the metal frame.
Okay thankyou for the reply. this instills a bit more confidence in me, my next question would be with the 150w driver and the .97 remainder is that close enough to fit an 11th strip/how do i tell if it is or isnt?
So if a driver only puts out 700ma max does that mean you can run 5 strips on a 240w driver (for my feeble brain to understand things better)
I feel like i should have clarified im looking at all the xlg lab drivers on digikey just to make it easier.
@Gpaw i think i understand what you are saying but then it clashes with reikos reply so im back to being confused (not with the wiring design though)
Im still at a point of working out how much light i need, i understand each strip produces 2390lm so on the low end looking at the 100w again ill be producing around 23900 give or take a bit and at the mo i cant find the umol rating though im not even sure what numbers i should be aiming at
Also i have seen a few different suggestions for wire gauge but the concensus is solid core which i can get behind (already had a go at pushing a wire in to one of those connectors) so any guidance would be helpful.
My comment referred to the series circuit. With a remainder like 0.97, you may or may not be able to add an extra strip. Or it may work when cold, but not when it gets hotter, or all kinds of other issues. Its best to save that extra strip as a spare IME.
No you cannot run 5 strips on the 240W driver. See how it has a minimum voltage of 178V? 5 strips would be 97.5 V.
Ahhh so if im inside the gap of voltage stated then its safe? ill be wiring in series just cause its easier to make sense of for me. Think i got my head around it. Now to buy myself a set of strips and drivers to play with.
I haven’t forgotten about you buddy. I would be happy to help you source the parts and muddle through it. What are we looking for? A 4x4 tent, mostly flower or a mixed spectrum? Budget? Dimming? Once you build your first, you will never go blurple again.
Hey man yeah everyone’s lovely, I’m at a tossup between a 100 and a 150 and 17 strips or 2 150s and 20 strips, still debating how much is actually needed per square ft as iv heard anywhere between 22w and 50w
here. But only eat half to start!
