Dimmable led lamp

frankie

Is there such a thing as an LED lamp that can be dimmed from daylight/cool white down to warm white?  Probably looking for GU10?

Looking at dimmable LEDs in general it is difficult to ascertain the dimmable range, any hints on what specs I should be looking at?

I want to illuminate above a largish dining room table so that it can be used functionally for work, but can also be used at a more ambient setting.

yes, at least as smart bulbs they do, but they will be dearer than non-dimmable/tunable & you may well need to control the colour change from a phone/computer. Philips Hue & Lifx both do them in GU10 but there may well be cheaper options.

In another thread someone recommends Philips Warm Tone as a non-smart option https://www.lighting.philips.co.uk/consumer/p/led-spot--dimmable-/8718696721674

Thanks BUFF.  That product looks interesting but it only goes through the warm range bracket.  I would want the range from cool to warm.

I'll look into your other suggestion re smart control options.

I haven't used any but the GLS-sized lamps from Philips, but their WarmGlow/DimTone (I understand they are effectively the same) are superb.

At full brightness, they are like bright incandescent lamps, not dissimilar to halogens. Ie - it's a good clean white light, but not 'blue' or cold (which is horrible, imv).

As they dim, they resemble ordinary filament lamps. In one setup, I have a wall light still with an old filament lamp and a Philips WG both set up on the same dimmer control - they dim at slightly different rates, but I wouldn't be able to ID which actual lamp is which, with the change in tone being that convincing.

'Daylight' might be a temp higher still - are you sure that's what you are after? Ie, do you want 'whiter' than halogen?

I control my hue visa hub. Not sure they (bulbs) can be run individual? Default on with a switch is bright white 100% on. The white bulbs you can really control the colour temp and brightness and the colour bulbs have quite a range. I understand ikea also do something similar?

The later Hue ones with bluetooth you can run without a hub.
I think that Ikea's equivalent still need a hub.

Need it pretty much daylight, I think. The table I want to illuminate is in quite a dark room, hardly any natural light. Want to be able to do close reading and craft type work so needs to quite bright, and then to be able to tone down for eating at the table.

Maybe I'm over thinking it. There's already a ceiling pendant light over the table with a 1500 lumen, 2700k 13 watt GLS LED bulb.

I had thought of placing 4 (or more) gu10 LED spots around the table to give more 'clear' working illumination, but that would also dim.

In a sense, you are looking to change the colour tone, but not necessarily the light output? Or even both, but independently?

Sorry, I don't know what to suggest.

Do you have the light fitting already?

There are many light fittings coming with a remote control that have the functionality you want.
