Hello,
First time posting in the lighting section. Our church has an addition with around 50-55 4'x2' troffer lights with dimpled diffuseness. These are all T12 with four 40w fluorescent tubes each. Ceiling heights are 8' and 9'. The addition is around 27 years old and we are starting to experience ballasts failures. I have been told for a few years now the T12's will be banned/discontinued. This got me thinking about LED tube retrofits. The kind that are direct wired using the existing tombstones but bypass the ballasts. A google search lead me to
these. Good reviews, used in the same application but I've never heard of them. Our utility provider does offer a rebate for each "bulb" that is replaced. The lights are on about 7 hours a week and I think our power rate averages 11¢/kWh annually. What are your thoughts or suggestions on this.
