There are options though. The picture below shows an LED lamp that can be retrofit into an existing or a new can. It replaces the reflector and trim ring for the LED lamp. This option might cost $50/lamp but these may last you 20+ years. The reflector and diffuser are designed for the LED light, so the output is better.
Well, what about your standard light bulb. There is a great option for that now also. Philips came up with a remote phosphor technology for the standard light bulb. The LEDs are arranged to disperse light by shinning through a phosphor coated lens which turns the Blue LED light to white. The light is even and can be dispersed in many directions. You can see in the pics below how it glows white and when it is off, the lens is yellowish. Remote phosphor is also available in other lamps like PAR lamps for your down lights or decorative lamps for chandeliers. It is a cool technology.
I think one of the key requirements for a descent LED lamp is that it is not a direct light. It needs to be diffused or reflected. The lamps with the multiple LED points shinning directly out of a fixture look awful. So, what about color temperature. How do you get that wonderful glow in a room like below? You need to mix light sources, or wait till LED starts providing a color shift along with dimming technology. You can bring in ambient light from LED sources and then use a lamp with a dimmed incandescent bulb to add the warm glow to a room.
So what is my point to this blog? LED is the future, I think it will be a good one, but people need to become educated on what is out there and what works. Most people who grab a lamp from Home Depot without much thought are not going to be too happy with the results. This is going to slow the transition for bringing LED to the mass market. If people are buying the right product, mfrs. will make more of it and the costs will come down. If you are building a home or remodeling a space, consider LED fixtures. They will last the life of your space and if chosen properly will provide you with a wonderfully lit space that will cost you pennies on the dollar in energy.
What do you think? Will you give LED a try? Questions?
