A lighting question

[clintyiu]

Troy,

I have just started using the Radium so life expectancy is a question on my mind too. Hopefully the blueline ballast helps here. You've probably read that they will last about six months with core and coil and 10-12 (even 14) months with a e-ballast.

Whether or not a "used" radium still has more blue spectrum than other bulbs is another question.
