UK to attempt to ban the sale of halogen bulbs.

<< < (5/14) > >>

TheBay:
The "Warm" Led bulbs seem to be nowhere near the kelvin of the incandescent bulbs, they are a lot warmer, certainly in the UK and for the past few years most of our bulbs switched to halogen which were around 3000K or more. These "Warm" bulbs just make everything look dull and tobacco stained, not to mention poor CRI.

Because standard incandescent lamps are 2700k and that is what most people are used to so most LED bulbs are also 2700k. A major goal in developing the bulbs in the first place was to make them look as much like what they were trying to replace as possible so ordinary people would buy them.

Personally I've started using quite a few tuneable CCT smart bulbs. I don't really care about the overall "smart" features but I love being able to dial in the color temperature. The Philips Hue white ambiance series are less than half the price of the full RGB bulbs and offer a very nice range from about 2200k to 6500k.

I like dimmed lights in the evening, kind of glowing campfire kind of effect.  Hard to do well with LEDs...

Yeah, I do prefer the warm white for general living area use and at night. When I said they looked horrible I mostly was thinking for use in work areas. On the other hand, the so called "daylight" (5000k+) to me, is far too blue to use anywhere. Maybe it has something to do with CRI.

Most of the ones I have look pretty close to incandescent. Halogen replacements for standard bulbs have been available but they've always been relatively expensive so they never really caught on here. The better LED bulbs typically have better color, the cheap ones often look a bit crappy. In a lot of cases I think the CRI has more to do with how good it looks than the CCT.

The Philips Hue white ambiance lamps do a pretty good job of it, going all the way down to 2200k. Philips also offers their "Warm Glow" series which are non-adjustable but get warmer as they dim. Not quite as nice as incandescent but passable for most of my applications.
