    Re: Destructive Incan Bulb Tests - Updated 5/22/09 (Newer Info Added) Is the reflectorised envelope opaque or slightly transparent? If it's opaque, wouldn't the beam shape be defined by the bulb envelope and not the reflector? Cheers! Sami

    Re: Destructive Incan Bulb Tests - Updated 5/15/09 (Newer Info Added) Maybe it's already been discussed, but has anyone tried relating filament length and wire diameter to the lumens vs. volts relation? That is to say, bring it down to the basic physics. Of course filament material maybe a...

    Re: Destructive Incan Bulb Tests - Updated 4/18/09 (New Info Added) I get it. You're going by reference values and from lux values, you calculate the lumens. Another question, I apologise if it's been already answered. Measuring an IRC-type axial filament bulb is simple enough, but what...

    Re: Destructive Incan Bulb Tests - Updated 4/18/09 (New Info Added) Lux Just a comment here, a quick calculation using the "new" lumen values that you calculated for the CL-1794 bulb give a rating of slightly above 53 Lumens/Watt (1333 Lumens and 24.96 Watts). I never thought these levels of...
