    There are LED replacements for some reflector lamp typs (spot lights) but I do not believe that they have created any for the larger lamp types.  This is due to the need for heat management at the LED.  You should always be careful when purchasing LED products as there are many low quality products out there.  They have problems with color consistancy and quality.  Also, if the heat is not managed correctly the life of the LED.

• New electrical wiring standard Guest (Rod) on 01/11/2006 at 12:00 AM

  Are there any plans for a new electrical wiring standard? I envision a new home being designed for LED lighting, instead of a LED light being designed around the existing homes. Would it be possible to have a very efficient AC to DC converter at the electrical box and feed 12VDC through the walls? It seems to me that it would make LED lighting options more flexible. I could speckle small LED lights over the ceiling instead of spotlights. That would also make it easy to create a battery backup for lighting during power outages. Would this option be more efficient versus each light fixture having it's own converter? Rate this comment: (Reply)

    Posts: 1	You can buy LEDs fixtures that operates directly with conventional AC 120 V 60 Hz, they incorporate the conversion electronics to do so. The 2 challenges to be resolved today: price and lumens/watt. But this will be solved in the next years as part of the learning curve process and manufacturing expertise. I have LEDs bulbs in my car. they are great !!. Rate this comment: (Reply)

• 	UV and LED's Guest (Mike Vitale) on 02/20/2006 at 12:00 AM
  Posts: 1	I have a question.  I read somewhere that LED's do not emit UV light.  Is that true?  and if so is there a possibility that in the future they will?  My concern here is the need for UV light indoors to stimulate plant growth (keeping in mind green-houses as well as indoor plants).  Thank you, Mike Vitale pops271@lycos.com Rate this comment: (Reply)

    Posts: 1	Dear Mike, Yes there are UV LEDs and Infrared. You can visit www.ledsmagazine.com as source of information. Your point is interetsing for plant growing since the wavelentgh could be optimized for fast plant growth. regards, Vince Sanchez Rate this comment: (Reply)
