Pratical, and so simple. I use it everywhere in the boat. Kill two birds out of one stone. Get a low energy but still pleasant warm white and allow to get red lighting for night navigation. I would prefer the red a bit less powerfull what I do by hidding 1 of the three red led with a sticker.

nice lights

There are two independent constant current drivers, one for each color. They are commanded through transistors from a microcontroller. To switch light color, you need to toggle the lamp switch twice, fast. Nice idea.
I hacked the board - removed the controller and connected the transistors driving resistors to the input wires - each to one input. This way, when you supply the board with - the light is white, when you supply - the light is red. Of course, the boat wiring should support this.

A brilliant alternative to other LEDs

They are expensive, but very functional and I will order them again.

They produce very good white and red light.

Question about delivery contents

Miguel V. | Jul 6, 2020

Dear Sirs, I hope all it is well with all team. It was supposed that one of the lights would be red but both are white. Could you please send the red one? I have an order pending to be shipped, 2286891, could you please add to this order. Many thanks. Best regards, Miguel Velez

Answer

W P. | Jul 6, 2020

Dear Miguel, this two-coloured G4 LED illuminant provides a pleasant, warm white light and can be switched to red light by quickly switching it off and on (within a second). When switched on after a "longer" timeout (a few seconds), it always starts with white light. Switching is best done with an ON-OFF-ON switch: if ON is switched from one ON to the other, there is a short interruption of the operating voltage. However, there is no switch position related to the LED colour. Please do not initiate changes in current orders via this portal. We cannot guarantee that your request will be read and processed promptly.

Technical question

Tommi J. | Jan 11, 2019

How does the light change colour white-red? Do I need to invert the polarity? Or is there similar quick on-off-on mode change as in item 21476 - combined anchor-tricolor light?
