I'm no electronics expert, but I have tinkered intelligently with an Arduino and have a fair idea what the circuitry in these things must be doing - so I'm tempted to try to hack one to make it do what 'we' want. But first I'd like to be sure no-one already has a much better worked-out solution? It may be, for instance, that a custom-made array of LEDs produces a more even beam of light than this 'bulb' could. I have searched archived threads here and on other forums, but can't see any completely proven set-ups.
Any more comments from experienced tinkerers would be greatly appreciated.
