green?!

Visitors Jeanie and Bill had their Meade 125 ETX at the RASC Toronto Centre Deep Sky Observing Session last night. When I warned that the humidity was rising over 80%, Bill headed for his car, and returned with some additional gear. A Kendrick wrap for the OTA. A power cord with CLA adapter. And the MICRO FireLite Controller. Tiny.

He plugged in the power cord but I wasn't sure it was seated properly. We checked the plug for an LED indicator. There was one. Good. We reseated the connector in the power tank and the LED glowed red. We have power.

I connected the dew heater to the controller. Very small plug. It was hard to tell if we had it the right-way 'round. But the fit seemed positive. I pressed the centre button on the controller. The first LED light up. Kept pressing the button. Second LED, third, fourth, then all of 'em. I assumed all meant full power. I suggested this, for now, to ensure it was all working.

But what struck me as odd was the output indicator colour. Why on Earth would Kendrick use green LEDs?! Four bright green LEDs in your face?! Makes no sense. It is especially strange given that the photo on the web site shows red or orange...
