28W T5 Retrofit Converter Kit


 These UL and UL-C certified IEUQ and IEUQ7 T5 conversion kits are designed to replace the T12 and T8 lamps quickly and cost-effectively. The kit is comprised of an aluminum lamp holder which houses the patented T5 ballast, patented safety end adapters for T12/T8 conversion, and the T5 lamp. Our Nano Reflector is integrated into the housing so the kit is a sleek one-piece unit that can be inserted just like a T12 lamp. 

The 4 foot (1219.2mm) T5 Retrofit Kit is the most popular size and a popular use in almost any application imaginable. The 4 foot kit is the only size in the T5 Retrofit Kit series which has a universal voltage from 90V AC – 300V AC and a bi-pin adapter for easy T12 or T8 conversion.
