Should note that not just incandescent bulbs are effected as some fluorescent are as well. The T12 tube bulb is phasing out and will be replaced by the T8 and my guess that in 2020' when the requirement goes up again, even the fluorescent lamps now will phase out as they will not meet the the new energy requirements. UPS is converting from the T12 now to T8's (some of you may have noticed your building getting a lighting upgrade recently) and we just learned a couple of days ago that our normal supplier for T12 ballasts no longer supply them. To say I was giggling at the thought of supervisors doing the Keystone Cop routine is understatement. Que the piano!
I've gone full LED at home (we love it) but you have to do the math and the application to make sure it's right. Fluorescent lamps do not like to be cycled on and off, this will lead to early failure and they aren't very keen on the cold either. Incandescent bulbs will be available but in a new energy efficient design. If you have a light that is turned on for short durations and cycled a lot, go with the new incandescent or consider stepping up to the LED.
We've been experimenting with LEDs in our building for several years and I love them. We installed LED's in our unload doors nearly 5 years ago and we've not touched them at all since. The old metal halides, would get a new bulb twice a year, ballast rebuild every 3rd lamp change at about $20 a pop for bulb plus my labor. Coil and core just under $100. The light form LED is also not near as harsh either compared to the metal halide. We installed one at the fuel island and a couple of wall packs mounted outside on the building with the same results. Never touched them while the other lights have been relamped along with new coil and core kits, some more than once. From a maintenance POV, LED's are a no brainer IMO. About to get some in the parking lot too (tomorrow) and looking forward to seeing (no pun) what the results are with them.
Rant away Moreluck cause the future is passing you by anyway!
