  • I meant to say that Granger has the 8 footers.

  • The ballast is an Advance RC-2S102-TP .85 PF

  • The 4 foot ones are still for sale in the Granger catalog. I have not seen any source for new 8 foot lamps. They are really bright when they warm up.

  • is this an HPF rapid start? Or LPF??

  • 8 foot PowerGroove lamps are still available, in cool white only.

  • So that's what those tubes look like starting up. Nice rapid start startup flicker. Do they still make powergrooves?

  • Cool bulbs! i want some of those.

    I see the fixture is home-made..out of wood (been known to do stuff like that myself)
