I know I visited this before.
Trying to determine how many drivers I would need per length of fixture. I drew red box around some of the info I knew for fixture. Input power from panel is 277v , output of driver is 24v.
Is it as simple as the fixture is 1.5W per foot and the driver is 100W so 100/1.5 is quantity of driver?

No experience, but since the spec sheet says "Fully rated to operate low voltage load at listed wattage (No derating required)" I'm going to say yes to that. I think some "100W" drivers have language on their spec sheets saying to only connect, say, 80W of load, but the above seems to rule that out.

One thing I'm not clear on is the part of the spec sheet that says 60W max output per channel. I guess that's for the DMX part. So while one 100W driver can supply 66' of the lighting, any individual run is limited to 40'?

Cheers, Wayne
