Some etch designs.

Here are a couple of etches I sketched today. From top to bottom, from left to right:

F40CW/WS, inspired by GE's 40s etches.
175W /C mercury vapour lamp, based on Sylvania etch design.
700W /W mercury vapour lamp, based on 60s GE mercury lamp etch.
And a 175W /N mercury lamp, based on 40s GE etches, but also from CGE etches on their 80s HID lamps. I think it's the best looking of the lot. Note it's a Lifestar etch too! (Equivalent to Bonusline / Mainlighter or Banner / Lifeline).
