I installed a lighted address plaque. The manufacturer shipped me an 18V (AC) power supply (which my multimeter says is more like 21-22), two 14V LED bulbs, and two 14V incandescent (possibly halogen) bulbs, all of which are "wedge" -- .27A bulbs (pretty standard). The plaque takes two bulbs.
The first night, I used the LED bulbs. One was dead by morning.
The second night, I used the incandescent bulbs. Both were dead by morning.
What could the problem be? Bad bulbs? Or, what I'm thinking, is that the bulbs are being "over-voltages" too much, if you will.
Any thoughts? I'm trying to figure out if I should get a new AC adapter (probably 12V, so I can use standard landscape light bulbs), or just new bulbs.
