Posting here as the lighting forum often gets more into style and design rather than technical considerations.
Today I converted a 4' T-12 fixture to T-8. Used Sylvania electronic ballast (bought a dozen of the ballasts and a box of the tubes) and Philips tubes. Ballast made in Mexico. Both components were selected for price-- were not the most expensive available.
The T-8 lamps start quickly. But at 70 deg, the ends get bright immediately but the center portion of the tube glows sort of red/pink and puts out much less light for some moments. Then very gradually gets whiter and brighter in the center of the length of the tubes.
This is in my unheated shop and I wonder what will happen next Winter.
Anyone done a conversion and what were your results?
