## Questions & Answers

**Q: Can these be wired directly to 110VAC without a ballast?**
A: The LED tube must work with a ballast which powered previous fluorescent tube.

**Q: Will the bulbs work with a starter?**

A: Mine give off just the slightest bit of warmth but nothing that I would consider "very warm" Hope that helps
