Yes, I have two from Semperlite and at least at the time they were distributing Sylvania lamps.

How is Semperlites shipping, do they pack them to survive international shipping ? because there prices seem pretty good and I can't find a CG light anywhere around here ..

Yeah, the lamps I got were well protected in a reinforced box.  It would have required excessively rough handling on the carrier's part in order to break them.  I've had good success with both Semperlite and lightbulbs.com.

Not a cool green flourescent-but a newly installed 400W probe start MH lamp installed in one of the high bay fixtures at work-gives a greenish cast-guess too much thallium iodide?It is an interesting appearence.Suppose this could be like one of those cool green flourescents-used to have a green flourescent bulb at one time.Think it got lost or broken during a move.

Bought a couple of Sylvania F40T12CG from Semperlite. Really nice bulbs, and Semperlite sells them for a very fair price. Not sure why the LG community hasn't bought them all up yet?!

In a Farmtek catalog I have they list green CFL bulbs for chicken houses-the green is supposed to be relaxing,calming to the chickens.I bought some CMH 315W lights from them.

I've got some Sylvania F40/CG in use.  The color is a bit bizarre, but is oddly beautiful.  Others describe it as "Mint chocolate chip" or "Coated mercury vapor", which I'd say is fairly accurate.  Next to something like Daylight Deluxe they definitely stand out.  I've got pictures but they don't do justice to the effect in person.

I forget what the lumens, color temperature, and CRI on F40/CG is (If I ever knew at all!) but it's supposed to be the most visually pleasing/most visually perceptible to the naked eye without being glary.  Mine are in the garage.  Had a pair in the kitchen but they made food look a little too strange.

I recieved an F24T12 slimline lamp from lightbulbs.com with a broken cathode. When I first powered it up, I wondered why a brand new lamp started acting EOL.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.
