I don't want any crappy Internet features in an LED lamp. It would be very good to be able to buy a lamp with a very high relliability and efficiency, like the Dubai lamp.
If it's going to have dimming, then it musn't be an LED reterofit lamp. Again as above, the lamp should be high reliability and efficiency. Ideally the installation should last for over 10 years, whilst maintaining >90% of the intial brightness. It should be nice and bright, with a full power setting of 5000 lumens, so I can use it for work. The dimmer control should be something fairly cheap and widely available, such as a potentiometer. No wi-fi, touch control, app, or any other rubbish.
Colour temperature control is handy, but I don't see the need to have a separate control for that. The lamp could have high colour temperature such as 5000k when set to 5000 lumens, going down to 3000k, when dimmed to 1000 lumens and 2000k at 250 lumens. That way I can have a high colour temperature, when it's bright and I want to stay awake and a soft, warm light, in the evening, before I go to bed.
I'd rather have a high quality product, with low running costs, rather than most of the consumer crap pushed nowadays.
