[Jukebox-list] AMI I-200

[Ron Rich]

Hi John,
  Thanks for the chart--it made me search out the lamp spec books that I had. According to both my "Sylvania" 1990, and my "Osram" 1996 books, there is an error on that chart. Both books show the # 755 as a 20 K hour life lamp, rather than 2 K. In my opinion, this, combined with the fact that it draws the same current as a 47 (.15), would make it the best replacement--other than the fact it produces a little less MSCD (.33 vs .50). If the lower light output is tolerable, it is the one that I think I would use. Ron Rich

I don't re-call off hand, and can't get to my lamp info at the moment, but I think the #47 lamp puts out the highest amount of light. I think that the only difference between the 44 and 51, is the envelope shape. All have the same ("bayonet") base.

As for the light bulbs the differences are important. The #44 bulb is 
the hottest, followed by the #47 (1/2 the wattage), then the smaller 
#51. I would recommend that you NOT use #44s under any peice of plastic 
that you care about - other than pinball playfields where you need to 
illuminate an insert enough to see it in ambient light. In our pinball 
world there are a lot of warped plastics and flacking backglasses 
exacerbated by the use of #44 bulbs.

I like the #51 as it is a smaller globe and less likely to overheat 
anything close.

I have a chart on flippers that shows light bulb characteristics:
