Philips Hue: Blue light emission

  • Hi everybody :-)

    First of all, a big THANK YOU to the flux team for creating this great app!

    I have seen several posts about the Philips Hue, and apparently you can even control Hue by flux. Does anybody know if you can adjust the Hue leds so that they emit no blue light? I have searched for a wavelength description of the LEDs used by the Hue, but I have had no success :-/


  • Yes the minimum color temperature is very low-blue, and the red is even better.

    The Hue is an RGB bulb (with a desaturated G) so it can achieve extremely low blue, unlike tunable lights that have two white LEDs, which cannot.

  • @justgetflux (you only have one post--should I assume it's the real people, or is this an incredibly informative knockoff account haha) so let's say that a LED bulb has two sets of white LEDs, that is, oh I don't know, how about a 6500K LED ring, and then a warmer 2700K LED ring. Is the 6500K going to be too much even at a lower brightness?

  • hi sorry I was still logged in.

    The Hue is RGB, so it's more like a computer monitor than like a warm-white/cool-white mixture.

    I have some data that suggests the Hue is generally extremely low melanopic impact - so for an equivalent color temperature, it has less impact than lights that look similar.

    This makes it hard to get a good daylight from it, but for night time lighting it is extremely good. The red is over at 626nm, so a red setting on Hue shows no blue light at all.

  • This makes it hard to get a good daylight from it,

    I'd like to read more about this, as I understand it does high color temps, but... it just doesn't quite look correct. As you've said the green is lower, actually Lorna said that several times, anyway, is this preventing it from providing a more vivid day time light? To add, is the green holding back the light output.

    I'd also be interested in the brightness of the individual LEDs if that's possible, I'm wondering how you'll find if you're using just the green!

  • thank you for your answers!
