I don’t go anywhere without a camera…….I’m always taking photos these days of anything that catches my eye.
Put one in your car installation inspector, you will be glad you did.

About 10-20% brighter, therefore they are more energy efficient which has an added benefit of reducing costs in industrial applications like warehouses. The reason is to deliver the warmer lower temperature colours the lights use a thicker coating layer of yellow or orange phosphorus material on the LED chips to convert the original blue/white light that LED chip emits to a warmer colour. This thicker phosphorus layer also blocks more of the light from getting out. Only until a point..6000k or 8000k will have a very blue hue and begin to become purple the higher you go and will lose output.. We have the LED downlights with adjustable switch and i have them set on 3k in living areas and 4k in bathroom..the 5k setting taints colours in the house and looks odd, i cant see where anyone would use it over the others.. Re: Downlights 75May 11, 2020 4:29 pm I agree with you, however It's a personal and cultural preference. The main reason for 3,4,5K is in the light there are 2 sets of LED chips: 3K and 5K. To deliver desired 4K on the adjustable switch from a minimum quantity of LED chips they mix light from 3K and 5K. This saves both manufacturing and supply chain inventory costs vs. having separate fixed colour down lights. Re: Downlights 76May 11, 2020 4:34 pm 2700K is the old warm yellow 60W traditional edison technology incandescent light colour. 3000K is light delivered by halogen incandescent bulbs which burn a bit whiter and hotter, and slightly more efficiently. LEDs have been designed to mimic these traditional bulb types but using about only 20% of the energy. Coffee shops will run approx. 2000K for ambience. |
