Is this normal?** A: Mine give off just the slightest bit of warmth but nothing that I would consider "very warm" Hope that helps **Q: What if the Ballast is not working? Will it still work?** A: These bulbs require a working fluorescent ballast. ## Frequently Bought Together - Lightwise LWL7W40-F13T5 21" Direct Replacement Led Tube, 7-Watt, White, 4000K, Retrofit 13W T5 Fluorescent Tube of your Uncder-Cabinet Lights 50% Energy Saving, Replace Directly Set of 3 - LightWise LWL4W40-F8T5 12" Direct Replacement Led Tube, 4-Watt, White, 4000K, Set of 3 - LWL4W40-F8T5 12“ 4Watts White LED T5 Tube with 4000K to Retrofit for 8W T5 Fluorescent Tube of Your Under-Cabinet Lights to get Over 50% Energy Saving!
