HID

[rmonroe]

We are considing replacing our HID with High Bay Fluorescent lighting. With the type of environment that High Bay Fluorescent lighting would be exposed to in our plant I have some concerns. The feedback that I get is ambient temperatures above 35 degrees C lumen output starts to decrease. Another concern is fine metal dust that comes from our product during processing. These contaminants are settling on our existing lamps and refractors and diminish our lighting.

Would like to have some feedback or any experiences.

Thanks

Re: HID

no matter what type of fixture, if you have a dirty environment, the fixtures will need to be cleaned periodically to maintain maximum output. Fluorescent lamps do have problems with too high or too low of temperatures, but the manufacturer should be able to tell you the lumen loss at different temps.

Re: HID

You are better off using a T5 lamp source since they operate at maximum light output when the temperature is 35 C. T8 lamps give maximum light output at 25 C.

Also, not matter what type of lamp you use dust will be an issue. Probably more so in fluorescent due to the larger lamp size and the electrical fields that like to attract little particles.
