Driver Selection help

So, the F Series are only 18mm wide which is just under 3/4". Only requiring 3/4" material is another advantage in favor of the Samsung strips and evens the playing field a bit more.

I'd prob use the $64 ELG-240-C1050B though.

The ELG series doesn't quite give you enough voltage (pretty close to being over max) to run 5 cobs unless you cap the dimming leads and run an open circuit. So you could use it but you'd have no dimming and it would max out at 239 watts. The HLG series gives you enough voltage to run it with dimming and gets the full 250 watts. It's nice having a tiny bit of headroom for voltage fluctuations.

The HLG-120H-C1050B fits 3 F-Series perfectly for 150 watts. $63 $0.42 per watt
The HLG-185H-C1050B fits 4 F-Series perfectly for 200 watts. $77 $0.38 per watt
The HLG-240H-C1050B fits 5 F-Series perfectly for 250 watts. $95 $0.38 per watt
The HLG-320H-C1050B fits 6 F-Series for 300 watts. $140cdn $0.47 per watt
(digikey prices)

So do these samsungs require more than 46v ea? 5x46=230, and both the HLG specs and the ELG specs show the cc range up to 238v (the "B" versions). Cobkits tested an ELG an found it performed pretty much in line with an HLG of the same size. Maybe I'm missing something tho?

sorry looked at wrong sheet

Too many tabs open lol

I guess I could go with the A version, testing shows 234v available, and I run a perpetual room and prob wouldn't dim anyway.

People went through something similar when Vero 29 gen 6 came out. Everybody was fitting 4 CXB's on an HLG-185H-C1400 and they fit perfectly. Problem with 4 Vero 29's on the same driver was the voltage was right at max. Sometimes it just wouldn't fire up for people.

The ELG might work even with dimming but it would really suck to order the drivers and find out one or all of them won't even turn on.
