Scan down to Annex I and then look for Intensity. Drink a cup of hi test coffee first.
Greetings,
Mr. ASD. "The oil from you hand will reduce the life of the bulb." Well, for all practical purposes yes BUT it's not quite as simple as that.
Halogens run VERY hot and the envelope is quartz glass in order to resist the heat. The moisture/oils from your fingers will be burnt into the surface upon illumination and subsequent heating. Over time, the surface degrades and amount of light put forth diminishes. Internal temperatures increase, thus causing the tungsten filament to potentially evaporate at a greater rate or the surface of the quartz to etch to the point of failure.
IF you happen to handle the quartz bulb, you can readily clean it off with rubbing alcohol with no negative effects BEFORE you turn it on.
Keep the lights, but man you need to spring for a new tape measure.?
I believe the inside of a light housing should be non reflective.
Like the light screens/shadowboards being painted flat black, if reflective it would make the angle of view too variable.
All measurements in diagrams of lights I see are from the filament.
This is why the argument about replacing incandescent bulbs with some LEDs has merit.
I also read that the inside reflective surfaces should be black not reflective which is the opposite of what I was thinking. Go figure.
Isn't black kind of the opposite of a "reflective surface"?
It is black because it absorbs all colors.
My Grand Banks has the Aqua Signal series 41 lights. I recently replaced their bulbs with LEDs from Marine Beam. That and the starboard side housing was cracked, and I found a replacement for it via eBay.
Aqua Signal series 41 lights are great--I think they are the way
to go!
Who knew that inquiry into replacement of running lights would morph into a discussion of this magnitude. That’s what is so great about the membership.
Greetings,
Mr. fb. " Exactly what was it that caused his entire body to go forward and off the boat?"
If you use an LED behind a colored lens, you do need to use the same color LED as the lens in order for the correct amount and wavelength of light to be projected. While using a white LED will “look” OK, you’re won’t have as effective a light as you would using the specified incandescent bulb. Search the COLREGS- the Coast Guard has very specific requirements for the type of light (the beam cast, not just the fixture) for each nav light.first base-
I plan to replace my running light bulbs with LED's soon. Never thought of using colored lights. Having done that would you recommend it? Instead of clear/white...?
