check one other thing. If there is sunlight or a bright light hitting
it it may be flooding out. Especially beware of any of the
"modern" bulbs. Cure is to remove the offender or put a small
hole on black tape & cover it. That works but your aim must be good.
I think these are pretty much the same. If its bad I would try one
that looks the same but check the pin out. You need ground, +5v & data out.
