<<To do
that, your little 75 watt bulbs would have to put out 250,000 CP. I find that
hard to believe.>>
Over
the years I've written much in the LML about these prototype 100 watt bulbs
made by an ex GE engineer for use in the MR16 format. When
compared at night side by side there is virtually no discernable
difference. These are NOT MR16 bulbs you can buy at any bulb outlet or
Home Depot. They are specifically made for a narrow beam landing light
with a special filament and reflector . I've sent many of these bulbs over
the years to Lancair builders and all have commented that they do produce an
incredible pencil beam of light. No doubt with accurate lumin measuring
equipment the xenon lights will produce a higher CP, but for the difference in
$$$$ most people are happy with the MR16's.
I
remember the first time we tried these bulbs at OSH around 1996. At the
parking lot, just going into the Lancair banquet, Rick Argente and I lit up the
hotel which was a block away. With the exception of one builder who
couldn't fit the bulb into his housing, everyone who has asked for a free
sample bulb to compare against their existing MR16 bulb have purchased a
dozen bulbs to last a lifetime.
