Yes, the DeWalt unit does look expensive for the relatively low light output. Unfortunately, as I previously alluded to, both of the other lights you found contain constant-current drives so that they are not simple to dim without opening them and modifying the in-built circuitry.
Actually, the place you put the lamp (bulb) is technically known as a light fitting or luminaire.
A very nice toy, if somewhat expensive, time-wise.(BTW, shouldn't that be 'formerly' in your bio., not formally?
Sorry, I forgot to mention that I just used a multi-meter set to A/C mV or A/C mA connected directly across the coil for the tests.Regards,
Thank-you for your comments. I have modified the steps slightly to incorporate your suggestion and added some more detail. I have also re-done the measurements with the actual coil from a scrap Braun toothbrush, so that could be an international 'standard' for comparison.Regards,

A good reduce/re-use/re-cycle project. Since this is a stereo radio, and there appears to be space for two 'speakers, why not fit two side-by-side? If you have the choice, a regulated power supply would give better sound quality with less 'hum.'
Rather than squeeze the ball, could you not suck the air out with a hypodermic needle and a vacuum pump? The ball should collapse under atmospheric pressure to ease insertion. The blemish would then be completely invisible and the ball would be fully usable if removed from the bottle.
I like the idea of an infra-red extender, but think this is unnecessarily complicated, decoding then re-sending the signal, and will only work with the selected protocol. Would it not be simpler to use an IR detector, amplify the signal, and send it down a pair of wires to an IR emitter in the room(s) with the device(s) you wish to control? This would then work with multiple IR controllers and receivers in any number of rooms.
