    Default Sealed Beam questions and Burgess Radar-Lite

    Hi,

    Picked up a Burgess Radar-Lite. What I know about it is that it uses a 928 6 volt lantern battery and it incorporates a sealed beam unit. I don't know at the moment whether it works. So a few questions:

    The sealed beam filament seems to be intact, so does this mean the sealed beam component is likely to work?

    Is the sealed beam component replaceable -- can I use an energizer sealed beam as a replacement?

    How do I replace the sealed beam, do I disconnect the wires from the old sealed beam component and reconnect them to the new sealed beam component?

    Etc.

    Thanks,
    Bob

    Yes. Unequivocally. Try across the terminals with an ohmmeter if you'tre not sure. If the filament is intact, it will work.

    Yes.
    The best sealed-beam light bulbs are the following GE bulbs:
    GE 4546 (4.7V 0.5A 6300MSCP)
    GE 4547 (4.75V 1.25A 20000MSCP)
    But any PAR-36 bulb with a nameplate rating around the 4.8V mark will work - just check that the screw terminals on the back look right.

    Short answer is yes. Not sure how you get the bulb out mechanically in this model; the bezel may be threaded, or there may be a nut&bolt at the back of the head. Examine closely and be gentle!

    The answer to this question is the switch. 99.99% of all sealed-beam lantern issues revolve around getting the switch working properly.

    Assume the contacts are corroded, and have gone high-resistance. The Radar-Lite looks like it has a slide switch, so it's not really replaceable without destroying originality. Blast the internal contacts, as best as you can reach them, with "Switch Cleaner/Lubricant" until it is nice and low-resistance (less than 0.4 ohms) in ther ON position.
    Then hit it with De-Oxit. Once you are down to 0.2 ohms or less, give it a shot of ProGold, and you are good to go.

    But if even after all that, the switch still has too much resistance to light the bulb enough, all is still not lost.

    Anyway, get yourself a battery and try it out and let us know.

    Hi lctorana,

    Thanks. Will keep everybody posted. I definitely want to see how this works.


    Note: Flashlight / Lantern appears identical to:

    Yup, that's what Google found for me, too.

    (Showed me the switch but not how the head or bezel is fastened.)

    To get to the bulb, you just unscrew the red bezel and the bulb comes right out. I silicone greased this bezel. Fortunately, the one I've got seems to be very clean and lightly used, so hopefully the switch will be ok.
