> Questions for folks who’ve done larger installs (10–50m) or more “production” setups:

> Do you design power delivery first or physical layout first?

I’m not sure I understand the question, power delivery isn’t designed, you calculate how much power you need and then buy an LED driver that outputs enough power.

LED drivers are typically 24W or 96W, so if you use LED tape that needs 2W/ft you can power 12’ with a 24W driver and 48’ with a 96W driver. You can use multiple drivers in a single installation, just keep the 12VDC output cables to the tape light approximately the same length.

> Any favorite diffuser/channel profiles that minimize hotspots without killing too much output?

Deep channel with a regular diffuser, preferably architectural/commercial grade. WAC Lighting makes decent stuff. You can get high output LED tape too, 200 lumens per ft which is 8W per foot, so a 12’ run would be 2400 lumens and 96W.

Cove lighting using LED tape is my favorite, it gives off a nice indirect light but building coves in a ceiling is time consuming.

> For long addressable runs, what’s your go-to strategy for signal conditioning (buffers, differential, etc.)?

I would use a DMX controller with shielded cables and let the equipment handle that.
