ZLL RGBW bulb not so warm white

[benerkens]

I bought a Zigbee led driver for my RGBWW / RGB+CCT LED strips, but the warm white was not so warm color temperature.

The lower limit of warm white was set to 2700K, couldn’t set lower, but I saw the WW leds fully illuminated together with dim illuminated CW leds.

I noticed that my Hue candle goes down to 2000K.

I went looking for the DTH of the ZLL RGBW Bulb and changed the 2700k to 2000K. Now the CW leds are off.

For my not so warm white CCT LED strip I found the DTH of the “ZLL RGBW bulb” somewhere and I changed the lower limit of warm white from 2700K to 2000K. Tried to upload the DTH but it refused to run locally, I had to set that to false. Now the LED strip shows the correct color temperature range, from 2000-6500K Renamed the DTH to -remote to prevent conflicts ZLL RGBW Bulb [Screenshot_20180725-215408]

PS it is not a Gledopto specific problem.
I returned zigbee led candle lights that were also not so “warm white”. Also due to the lower limit of 2700K?
With the LED strip I could clearly see that the CW leds were still shining.

What’s the brand and model of the various devices involved?

I had a Osram/Sylvania candle E14 that I returned because of the not so “warm white” color temperature.

I couldn’t see the leds inside the bulb, but with the knowledge now, I think that the lower limit of 2700K, set by the SmartThings internal driver (local) was not low enough to get the bulb in warm white (WW).

Can’t confirm it, I returned the bulb. Maybe others here have the same experience with RGBW or RGBWW lamps.

The same driver I modified to 2000K-6500K and now I have a better result.

Hope that it helps others, this information.

PS the LED driver now is a Zigbee device from Gledopto, the RGB-CCT version, together with RGB and CW/WW ledstrip.
