I only needed 3 spares and bought a pack in case they burn out. One broke and the other 3 didn't work (I haven't even tried the last 3 that I keep, but I think some of them don't work either). Expect about 50% of the bulbs to work. pretty sad. Thought I'd get a good deal on the price here, but if only 50% works it's not cheaper at all.
