Light Bulb vs Litebulb

Is it common that LED modules go out? I only ever see power supplies be the problem

Wait, what are you putting T5's in? We almost exclusively install T12's in signs.
As far as the 4' LED lamp, 240W is way out of line, at least for what we've been using. Principal XL sticks as an example only pull 18.6 watts on a 48" double sided stick. So that gives you 6 sticks($45 each) on a 120 watt power supply (@ about 2.2 amps, $55/power supply), vs a 16L to run an equivalent set of fluorescents($10 each) (@ 3 amps, $130/ballast).
But that is all beside the point on new builds for us. The fact that you can screw 6 of these in and wire them in under 30 minutes, vs punching and installing 12 sockets in a raceway lid (cost of sockets to boot!), wire opposite ends of the lamp, then check to make sure numb nuts built the cabinet long enough for the lamp to fit (it's hard to shave 1/4" off a lamp).

Plus they have this sweet 10 year parts warranty on almost all sticks and power supplies at this point, 5 years for labor up to $100 per power supply.< This is what sells leds to most of my customers.

I was talking shop lights. Gino said lights in signs are lamps, Burton. 2.3 vs 3 amp kind of kills the whole energy savings argument. Plus the E-waste is starting to get regulated more so eventually you will have a box full of busted LEDs to haul off as haz-waste.
Tex LED diodes do burn out, not sure how quickly they do in the higher quality brands though. They also lose intensity over time the same as fluorescent so eventually you will be re-lamping LED cabinets just the same. The thing I like about LEDs is that I don't have to use spell check to write it out.

Yeah, but the speed at which you can throw them in signs/warranty was my selling point. Also the reduced storage space and inherent resilience of an aluminum stick vs glass tube during transport is very nice, just gotta figure out what to do with the 10' deep bin once they are fully phased out.

I agree with you there. Turn it into a smoker, the mercury should burn off pretty quick.

Doomed! Here's a better solution for climate change.

Colossal goat f*ck.
