My Airport Operations

Tom at ADB.  ADB Airfield Solutions only purchases lamps from known quality suppliers such as (but not all inclusive) GE, Phillips, Osram, etc.  Mr Zukowskis claim is absolutely false.

One more comment - the meter must be TRUE RMS.  We recommend models made by Fluke.  Fluke 87V is a good one.  An internet search on Fluke 87 should bring up multiple sources to buy one.

Tom,

I think your right on, I have replaced the original blubs with GE and they have not given me any problems. I will double check my regulator with a RMS meter, which is something we have not done. I have to say that it was the weirdest thing I have ever seen, the material was “boil” out when power was on.

Thanks for your help,

Glen

even etter, if you adjust your regulator to the lower end of tolerance for each step you will et improved lamp life

usually this is one of two things - buying lamps from a discount provider that is of lessor quality - for example, your local large home store lamps likely will not last as long as GE or Phillips, or, and the first thing I would check, the output current of your regulator is higher than the recommended level per step.  This can happen for many reasons.  Measuring ccr current must be done with an RMS meter or you will get a wrong reading - this is often the reason we see regulators are set wrong - using a non RMS meter.

if u cn let me know the results of such adjustments

Thank you jasbir, I will look into adjusting the regulator.

we adusted the current to step 4 and the outage  was  reduced  and the life of the bulbs also increased u may  try this.

Osram Sylvania lamps are junk, buy almost anything else.  Once did a TWY project and installed about 300 new fixtures, all with Osram lamps.  They starting failing right away, many of them exploded with enough force to shatter the outer lens.  Ended up replacing all the lamps with GE lamps (under warranty of course).

Had same problem here, again this post may be a little late, but Isabel is right GE makes the best bulb I have found. Osram Sylvania light bulbs don't last near as long in an airport environment. I have tried just about all of the other bulbs, (many a lot cheaper) and always went back to GE. It will be NICE to look out on the field one day soon and see ALL LED's.

These are made by Osram and they are less than a year. The material between the glass and the outer shell. Has turned to powder and is "boiling" out. Never have seen this before.

Here is a picture of the bulb. The 'insulation' is falling out.
