My daughter has become VERY good on the piano, and normally we have been turning on the 50W room light when she plays and practices. Can't have that! a dual Cree XR-E Q5 lamp was in order. This thing works better than I expected, and survives at 500mA drive just fine. 350mA barely gets warm... and is gobs of light.
Nothing fany here. Goal was to shield the player from the emitters,
and let them spill everywhere else. The "fixture" is a length of
aluminum stair nose protector, normally used for exterior thresholds.. Benefit
is that it has a rounded front edge so it doesn't just scream "angle
stock." Drilled a hole in the middle for the Lockline connector, and
made a bracket for the back of the music stand.
Here is looking up the thing. Like I said
- nothing fnacy here! Just pure function.
Now here is the real efficiency beauty of
the whole thing. The Piano is already powered by an 18V Wall wart, so I just
tapped into that power line. The power is fed to an nFlex, and away we go.
So no extra wall wart needed, and I'm adding 2W to the already over-spec'd
converter. Everything is quick-release so I can get it all back apart when
I want to fool with it. Leaned that one the hard way!
