The party never has to end with the Feit Electric 18-watt (32-watt equivalent) Black Light Direct Replacement (Type A) Non-Dimmable Linear LED Blacklight Tube. It replaces T8 fluorescent and LED tubes, fitting into most existing ballasts for quick and easy plug-and-play installation. No rewiring is necessary. Get the same blueish-purple glow-in-the-dark light for Halloween parties, birthday parties, raves, nightclubs, and DJ sets, while saving on energy costs compared to traditional fluorescent linear lights. The T48/BLB/LED blacklight turns on instantly, offering flicker-free full illumination. It doesn't need any warmup time like fluorescent tubes. It is mercury-free, with a shatter-resistant coating for safe and easy disposal. Lower heat emission extends the life of the tube and ends do not turn black or burn with age. The estimated energy cost is only $2.17 per year. Switch to Type A LED linear blacklights and kick up your celebration with glowing decorations, clothing, accessories, body paint, posters, and artwork. This long-lasting LED tube shines up to 50,000 hours for over 45 years (based on 3 hours of daily use).
