    ~12 Watts at 120 vac Nominal, Converted Bulb.

    posted by apoapsis on 07/07/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Converted bulb tests 110 ma input at 119.7 vac, and supplies ~2.95 vdc (close to the 3 vdc nominal) to a typical LED in 224/225 array. Appears as bright as original 240 vac operation.
    Cons:
    Takes a good hour to convert from 240 vac to 120 vac use.

    120 vac Successful Operation.

    posted by apoapsis on 07/06/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Can be used at 120 vac if modified, as previously noted, and by increasing the input capacitance by 10 mf. It now has the same light output as the original operated on 240 vac, and has the same LED voltage, 3.00 vdc +- 0.01 vdc.
    Cons:
    Takes about 1 hour to modify each bulb and requires a small 10 mf capacitor (200 - 400 vdc rating).

    Jumpers, etc for 120

    posted by apoapsis on 06/28/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Can be slightly rewired for 120. See uploaded photo.
    Cons:
    The light output is less than the 240 original. The LED voltage is reduced to 2.71 volts dc from the nominal 3.0 volts dc. Perh...

    Very Tiny Tester Grabbing Hooks

    posted by apoapsis on 04/28/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:
    This is about the smallest testing hook I've ever seen, and this makes it ideal for working in very tight locations. The build quality seems very good and the spring loaded action feels dependable.
    Cons:
    Having an assortment of colors for these hooks would be an added treat. Different colors are useful in circuits where (color-id...

    Test Small Parts

    posted by apoapsis on 04/28/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:
    These hooks can hold very small parts, even those with very closely mounted leads. Spring loaded action seems to be of durable quality.
    Cons:
    How about some red clips at this great price and quantity? Using all one color can lead to polarity mistakes, whick can sometim...

    Nice To Find At A Reasonable Price

    posted by apoapsis on 04/13/2010 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    The regular 9 volt battery for my stud finder was getting a little weak, so I tried this one right out of the package. It does measure a little lower voltage than a regular 9 volt battery, but it seems to have a good capacity and running life.
    Cons:
    None that are apparent. But after it has been recharged a few times things could possibly show up.

    Value For The Price

    posted by apoapsis on 04/13/2010 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    For general everyday usage this is a great bargain at the price.
    Cons:
    It is hard to adjust the laser beam to shine where you want it to. Not the idea of how to do it, but the fact that the adjustin...

    LED Actual Working Voltage

    posted by apoapsis on 03/18/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    I was able to test the actual working voltage of a 224 (225) LED connected to ~220-vac and lit. The voltage varied between 3.00 and 3.01 volts DC.
    Cons:
    I hope and assume that this was a typical point in the bulb circuit, but I can't be certain.
