Message: [QUOTE="NJCuse97, post: 3383808, member: 5058"] I agree, LEDs are costly and they have come down in cost considerably. The pitch I have heard (and made) is that the buyer needs to look at lifecycle cost, not up front cost. The LED will use less energy and the fixture (LEDs are technically not "bulbs") will need far less replacing than an incandescent does, like 3:1 or 4:1 so over the life of the fixture, the $5 bulb is $20 and the energy savings should balance the rest of the cost. At least that's the pitch. In the case of The Dome or the IPF, there is also a savings in changing the bulbs which represents risk, equipment rentals, and facility down time. This was one of the reasons for the old traditional sodium lights for street lamps, metal halide lights, etc. Trouble with them is it take 30 minutes for them to warm up and they are typically very cold in color temp.
