Radium 250w & 400w bulbs

[ZR440]

I have for sale two lightly used Radium bulbs. The 250w has 5 months of use @ 9 hrs. per day. The 400w has 3 months of use @ 9 hrs. per day.

50 shipped to your door for both bulbs.

It'd help if you posted what ballast these were run on. 5 months would be near end of life on some ballasts
