Effect of fitting on temperature A quick test with a thermal camera. Shown is two pairs of 36w T8 Philips lamps running on the same model of Philips HF ballast. It's interesting to see just how much the fitting affects the temperature of the lamps. The phosphor temp in the middle was 37'C for the batten fitting and 43'c for the louvre fitting.

These thermal pics are quite cool to see. Would be interesting to see the difference between 4 of the same tubes like Philips 840, 2 on HF and 2 on SS to see if there is any temperature change between the 2 sets of tubes on 2 different gears after a hour running etc.
