Good stuff guys!,
I am also a big fan of the newer T-5 fluorescent fittings.
I've used them in quite a few applications, including factories, the "yards" of a slaughter-house, they even make a street-light-type fitting that uses these lamps.
The only down side to these fittings that I have experienced, is temperature changes can cause the light output of the tubes to vary slightly, but it is not a big variation.
I would be interested to see how a M-H lamp actually stacks up against a T-5 fitting, using real-world analysis, not the information given in lighting company literature, where the tests are often done in some sort of a laboratory.
I believe the first place to start would be comparing the output of the two lamps in lumens/watt.
Any takers?
