Sylvania F48T12 Gro-Lux VHO LifeLine

Sylvania F48T12 Gro-Lux VHO LifeLine

Click to view full size image

A Sylvania F48 Gro-Lux (standard/narrow-spectrum) VHO lamp, and a LifeLine at that!!
Well...this is one way to make a Gro-Lux have some brightness to it
Picture doesn't really do it justice, color is close to what you see at the bottom. (maybe this woulda turned out better if I put it on a normal ballast & dimmed it .LOL. )

When I first fired the pair of these up, the ends of them blackened noticeably, but after running for awhile they cleared up...I guess "burning off the newness" of something old but unused & sat for years?

Got this awesomeness from veryhighonoutput!

Probably condensing Mercury vapor starts to evaporate when it warms up, xmaslightguy

Pretty, please no more Chinese failure.
