pretty amazing, to me anyway. Jameco rated them at 4

candles at 20ma, which seemed a little 'opto'mistic.
I tried them out, and they reach near peak light at more like
180ma, getting just noticeaby warm. At 250ma they are
'uncomfortably' warm, hence question:
Did they really mean 20ma? at that proportion they're
putting out <10% peak, but 180ma is WAY above spec,
Jameco's spec anyway. So I guess Jameco's wrong?
Could I be loosing lifespan at this current? Maybe the
not-too-warm test is good enough?
Totally untutored guess: A "noticably warm" bulb is fairly likely to
shatter when a glob of snow falls on it.
