This is a NOS (brand new) Philips arc 80. It runs on a 45w Cpo-tw lamp and has a leafnut Harvard node on it, also it has been painted the Surrey Green colour. It is actually a Philips arc 80, however it will always be WRTL to me. This one has also got a different optic system to my Wrtl arc 90.

To open the canopy, undo the metal clip at the front and lift up the canopy so it can lock into place. Click on any of the images below to make them larger.

Here, you can see the Harvard electronic ballast, the leafnut node and the 45w Cpo-tw lamp.

Here is the Philips sticker.
