LED Lights

[jerld]

Yeah, when I was remodeling my home, I was thinking about installing some LED fixtures; my San Francisco electrician buddy was telling me they aren't nearly as good in almost all areas as the T5 or T8 fluorescents. The thermal degradation is significantly more in LEDs, T5s and T8s are more efficient and produce more lumens to the watts they use, and LEDs have a higher heat dissipation percentage that will drive up cooling cost in a building and possibly reduce the life of the fixtures. Also, the initial source cost is more to implement them, especially in larger commercial buildings.

At present your friend is correct.

LED lamps are better for locations where a CFL or T5 isn't such as cold areas - a porch lamp for example.

Another great use for an LED is night lighting - where you only want adequate light to navigate by.

Soon as I manage to get our electrician here we are putting them along the entry walk/drive - 50 meters of uphill. It will be interesting to see how that works.

5050 LED's

I have been playing around with LED lighting for years now. I know the first ones were terrible very little and very blue light. I have been testing the newer bulbs using the 5050 LED chips. The light is a nice warm white without too much heat. Pulls 6 watts and has the light output of a 60 watt incandescent. Instant on with no flicker. I have 5 in a ceiling fan testing them out at this moment. Very bright, however the only downside is they don't dim very well.

Is there a standard for LED street light, I mean for temperature equivalent? Usual temp is around 5500 Celsius degrees. I can not find that standard.

[Naptown]

Wow 5500 degrees Celsius is hot!



I think you mean Kelvin which the color temp of light is measured.

[bjdarko]

OK, may be you right, thanks. But do you have any suggestion for the standard?

[Naptown]

They come in a variety of color temperatures
I believe 5300K is the color of an incandescent lamp.
Here is an explanation

[bjdarko]

I think these are the values: 2,700

[elisa123]

Yes, what you mean is color temp, but the temp of the light.
Actually, different factories have different stardards for the color temp.
Some just use warm white, day white and cool white to define the color. Also the factory can make the kelvin according to your need. There don't seem to have a Unified stardard.
