No worries,
Very good point on the smooth reflector, thank you for bringing that up. I just took it for granted that if it is the 13139, it will be smooth.
I have 5 on the way, so I will check them as soon as the arrive and report back for others thinking of stocking up.

Anyway, the message is: be careful, EFP=1,000 hr. , EFN=50 hr.

BTW, the eBay add for the "13139" lamp shows the picture of a faceted reflector lamp.
The real 13139 has a smooth reflector. Maybe the picture is just illustrative, not exactly the lamp for sale.
