This might actually fly as a "night light" and allow me to add motion to the bathroom (wife thinks others look too much like cameras)

There is no white though.. Keep that in mind..

Will it go purple? That would be more then enough for my wife.

Amazon says - "Color options include red, green, blue, yellow, magenta, cyan and white."

I guess no purple! :cry:

Yes.. It’s RGB

Well that amazon description is wrong.. :face_with_raised_eyebrow:

It uses RGB values..

Bryan - "White" is the most difficult color to produce since it mixes it from Red, Green and Blue. In early samples, white had a cool bluish cast. In the most recent samples, it's closer to orange! As for purple, "Magenta" is very close to that. Good luck with the testing!


I actually have an algorithm to reproduce full color temperature with just RGB.. But so far I have found color reproduction a little off on this guy.. I’m going to keep poking at it to see if I can get it more accurate

Really? If you figure that out, I'd like to see the results. I did not think that was possible.

This is RGB LED Strip.. RGB Only reproducing CT transition

From another driver of mine.. It can do 2700-6500K

I might have to make a custom gamma correction on this to make whites work properly..

I like that little sensor. I've looked at them probably 10 times. They are just too pricy for me to justify. But very neat.

If they ever have a 3 for $99 deal I would bite. lol

I like that it will never need a battery.. and the motion sensor detection is fast (1 min minimum switch to idle) but it's the detection that matters..

Illuminance sensor seems to have a good range

I'm still playing .. but so far it's a pretty solid device..

I just like the programmable light. I would use it for house status, like alarm on. I'm not all that interested in the motion (have GE Motion Dimmers everywhere) or illuminance (don't use that).

It's just a unique device, and I like it.

illuminance : 13307
illuminance : 10

the 13,307 value was a bright led light right against the sensor

That's definitely a cool feature. After we added that to the HSM200, we added it to our light switches too!


Yeah I'd take that. $57 bucks is a bit much, unless they could add a humidity sensor. That would make it the ultimate bathroom sensor (need humidity to control exhaust fan with shower)


Yeah, I stumbled on this thread while shopping for night light options. The Dome DMEX1 is a great option. Somebody, please sell me on this $57 sensor. Or, is it just too much for night light use? $35-$40 seems like my sweet spot.

Oh, thanks for the driver @bcopeland
