Green Sylvania Incandescent
No video for this one, there's not much to see with an incandescent lamp starting up!
Bought at a Wal-Mart in Southern California in October 2016, an innocuous looking green lacquer dipped incandescent lamp but interesting on several counts.
Firstly, notice the "Made In USA" mark, which is unusual on any lamp these days. The address given on the lamp sleeve refers to St Marys PA where there is indeed a Sylvania plant.
Secondly, a 38W rating which is the first time I've seen a lamp for the US market with this rating.
I can only speculate why this lamp was made, as in 2016 you don't expect to see new incandescent lamps in Wal-Mart, of all places. Perhaps to meet a US-made quota, perhaps to keep a manufacturing line busy. As to the wattage, I suspect (again, I have no direct knowledge) that the rating is in order not to trigger any energy regulations scrutiny for this lamp, whereas if it had been made in a 40W rating, it would have. Here in the UK I've seen 60W class incandescent lamps rated as 55W, perhaps to bring them to a better band in EU efficiency rating.

The lamp isn't particularly good quality, as can be seen the lacquer coating isn't even, so a mixture of green and white light can be seen.
The etch looks like older styles of Sylvania etch, there is no evidence of a date or factory code anywhere on the lamp that I can see.
