    Help needed from someone with a good memory....

    Hi folks... does anyone out there know the correct rating for the bulb in the SEI Photometer - Is 6 volt 6 watt correct?
    Thanks for all and any info

    Not 6 volt 6 watt, Inside you have a 1.5 volt D cell battery.

    I used a No. 131 from Bulbster.com

    1.3V .1A/G3-1/2 Mini Screw Base

    SKU: 40252

    I don't see the bulb rating on page 10. Can't imagine a D-Cell even making such a bulb glow.

    The original bulb was frosted, the replacements are clear, so I "sanded" the bulb to make it frosted.

    A closer reading shows that PDF page 20 refers to an external illuminator accessory rather than the internal lamp.

    Now THAT, I believe. Sure would be nice to have an external standard illumnant. Instead I just adjust the bulb until the dial agrees with one of my other spotmeters then I mark a needle line on a piece of screen protector.

    Try this - it is Roger Hicks web site, and he has some good stuff there.

    There is a LED conversion made by huw@huws.org.uk.

    Don't know anything about it but it might help.
