Converted Thorn Guard light

Originally a non maintained 4w affair, the batteries leaked & the circuit was doa, so junked it all & converted to SS using a Tridonic 4/6/8w Ballast & a potted pulsestarter. Probably runs the tubes harder than a dedicated 4w ballast would.

Yes, I guess when the ballast manufacturers say 4/6/8 watt, they run closer to 8 watts!, but the tube looks well on it Cool

Very nice fitting. Those Thorn tubes are really good. I got 4 years of very heavy use of one running on a Tridonic EC 4/8 ballast.
