Thorn Gamma 6 18w SOX: 3y, 8m, 21d

The 18w Osram SOX lamp in the Gamma 6 on my patio has now completed 3 years, 8 months and 21 days service.
I noticed it had a slight intermittent flicker the other night when it first powered on and warmed up but it seems fine now.
Decided to have a look today and see how its going.

The blackening around the electrodes that was on the lamp from new disappeared after a year or so and was replaced with that white staining and splatter that you can still see but the blackening has now returned around the electrodes and there are also black spots at the bottom of the lamp around the U bend.
The section of arc tube in and around the U bend section Is also starting to suffer some slight blackening.

Quite a difference to the 3 year pic!

This isn't coming out until it's dead so I wonder how much longer it has lol.

Interesting to see a Gamma 6 with an 18W lamp in it

Ria in Aberdeen
It'll be all right in the end, and if it isn't all right, it isn't the end :love:

Yeah one of my customs. When this lamp failed I was going to swap it out yet again and fit 35w SDW-T lamp & gear in it but decided on another 18w SOX.

UK out of the EU!
