My Streamlight TL-3 bulb. I recently felt it not as brightly as before. Then after checking, I found bulb became grey. It should be due to the tungsten vapor attached to the glass.
I do not expect this because I ever saw similar small flashlight bulb as transparent as new one when running out.
So I want to hear your comments about it. And two questions,
1. For my TL-3 bulb, was it because I used 2 16500 lithium-ion instead of 3 CR123A that led to the black?
2. Does halogen bulbs normally remain transparent as new when running out? I assume TL-3 bulb is not halogen, at least not full halogen filled.
