30V > 3V

The tiny LED is a Nichia NSSW157T running at 80mA max. It's supposed to spew out 30lm with above 100lm/W and heats up close to untouchable without PCB contact. It's also equipped with an additional diode (0.7V drop) for reverse voltage protection of the LED chip. The G4 replacement PCB uses a PT4115 buck controller, 68µH inductor, diode, electrolytic capacitor and a bridge rectifier. It is not as bright as the 20W halogen light bulb and much bluer, but my goal is to starve my utilities company and save every single mWh I can find ;-)

0.99€ down the drain. Nichia NSSL157T-H3.

These LEDs are about the size of a match head.

This contraption is quite useful for extreme macro shots.

I had already written it off, but it seems to be getting enough light now.

Why did they glue down just one of them?

No dolby whatever for me.

Don't you just hate it when wires are directly soldered to a PCB and they wiggle and jiggle and finally break. Won't happen here.
