General Electric 250w Arcstream 742
1 x General Electric 250w tubular quartz metal halide lamp in colour 742.
Quite a nice lamp with a decent colour!
It's interesting to compare this lamp to an older UK made GE Thorn example that I have.

That a nice later example which still appears to be of excellent quality!

This has a very nice colour when lit. A lovely pure cool white without any yellow tint.

Nice lamp! Quite a colourful halide does in it too Smile I assume due to the 'H' in the code is is for Horizontal burning only?
