Amazing Lamps - Page 3

unique, yep you're right on target! Hey 1 in a million wouldn't even notice such a thing. I'd say you have observant clients. Those little 'balls' should go away after the lamp 'settles in'. How many hours do you have on them now? I'd guess less than 100, am I right? They gradually go away as a natural part of the lamp burn-in process, so its nothing to worry about. The BLACK area, that looks like smoke at each end of the lamp as it ages, is quite another thing. These blackened areas are signs of TROUBLE. This is an accumulation of 'getter' material coming off the cathodes as they ignite. It happens because of the power surge that takes place when the starter heats the cathodes. It acts like a switch, zaps the cathode, then opens like a switch. The NEW electronic starters ramp up the voltage to the cathodes, and eliminate the cathode 'zapping', thereby stopping the breakdown of the cathode and its subsequent deposit of residue on the lamp glass. This 'ramping' in turn leads to longer cathode life and ultimately longer useful life of your lamps. The electronic starters are most beneficial in 160W and higher applications.

bsmart:

Was the UV"B" & "A" read and configured into the output? This was not clear. I do think that there is one other lamps that should be tested with respect to longevity, customer satisfaction and output results.

Most of the lamp manufactureres in past years expelled the belief that lap swill last much more than 600 hours (100W) and 450 to 500 (VHO-160W). We have experienced an average of 800 to 850 hours (100W) and little more in the 160's,with good results. This is using extended anodes with race tracks, special glass, imported psyphors and all the other good stuff!

Also lamps that are supposedly produced to be the same output may have many outside variables, even if the same components are used repeatedly.

Lamps that are assessed to be the same exposure times can have the same output withiin the first 100 to 200 hours. After this the drop off varies. Two seperate psyphors with matching VU characteristice will meet the accession times, however one may be of a more stable source.

Roger, I got my UV numbers with the 5.0 Solarmeter and my tanning times with the 7.0 Solarmeter. I do not have a 6.0 meter to measure UVB alone. So, I guess the answer to your 1st question is, No.

I am reporting on the types of lamps I currently have in my salon. What other lamp were you referring to in your opening statement pertaining to testing longevity? I would be happy to test a set of lamps of your choice if you care to 'donate' them for the cause. I do have a set of lamps coming from Philips that I will be installing in my bed #4 pretty soon. I plan to report on my findings as these bulbs go thru their life cycle.
