Up to now I have heard that it was best to turn on your high intensity fluorescent light box on at the beginning of the printing session and off when you're through using it for the day for two reasons: 1. Fluorescent tubes take a while to warm up to full intensity. 2. The bulbs will last longer.
After watching some Platinum printers on YouTube, I see most them using their high intensity fluorescent light boxes on timers just like you would do when using an enlarger. Asked an electrician if turning fluorescent tubes on and off a lot would shorten the life of the tubes and was told yes but only after turning them on and off many thousands of times. Also the warm up time is insignificant in a room with the air temperature of 70 degrees. A relative is a retired electrical engineer, and he told me not to worry about using a timer with today's fluorescent starters and tubes.
Can anyone out there shed some light on which procedure is the best to follow?
thanks
