The discussion of lighting below prompted this.
I have a case (10 tubes) Of Phillips Instafit LED replacements for T-8 florescent tubes.
They actually belong to a friend or mine and are available for $50 with free shipping.
There are supposed to plug directly into a four foot fixture in place of t-8 tubes with electronic ballasts. I am not an expert on this. Look them up and double check.
If you want them let me know and I will connect you to the owner.
