If the starter is causing problems, the bulb will flash. **Q: Just received these. I ran them for about 2 minutes and they get very warm. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Direct Replacement LED light tubes worked without having to modify existing light fixture ballast! *by J***D on Reviewed in the United States on 21 February 2024* Wanted to replace the existing 21" fluorescent light tubes with LED ones without having to modify the ballast in the light fixture. Found these Lightwise F13T5 Direct Replacement LED light tubes on Amazon that fit this need. The existing light fixture and its ballast is very old (perhaps 30-40 years old?), so was unsure whether these Direct Replacement LED light tubes would actually work.Installed two of them in the light fixture and actually held my breath while flipping the light switch on. Was very happy and pleasantly surprised to see the new LED lights immediately turn on without any flickering. They were a perfect fit and installed much like the old fluorescent ones...just needed to make sure that the LED lights were oriented downwards after being seated in the socket. I like the 4000k brightness and they are cool white, without a purple/pink tint like a few other reviewers encountered.Time will tell whether these LED light tubes last longer than the last set of fluorescent ones did (i.e., those were terrible and would burn out every couple of months). So far, I'm very happy with this purchase! ### ⭐⭐⭐⭐⭐ Good value for the money, super bright too. *by D***F on Reviewed in Canada on 6 July 2019* Great replacement lights. I had two of six of the old fluorescent bulbs blown out. The price for those was virtually the same, except that it costs allot more to use them vice these! I originally bought a pack of 3, when they arrived and I installed them, I had to buy more and subsequently bought another two packs. Tome you can’t go wrong with these bulbs. ### ⭐⭐⭐⭐⭐ T5 7W LED light is brighter and easy to install *by V***I on Reviewed in the United States on 29 April 2024* This T5 7W LED light replaces my T5 18W light is easy to install and has less power than the standard T5 18W light. It should last longer than the standard light bulbs. Immediately, I can see that is LED replacement is brighter. I changed all 4 light bulbs to LED light bulbs. ## 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 12β€œ 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!
