Environmentally Friendly Replacement for Halogen Bulbs...

Environmentally Friendly Replacement for Halogen Bulbs...
I was looking around the Farnell website the other day, as we are renovating our apartment and want to install energy efficient lighting throughout the flat, and I came across these LED replacements for Halogen bulbs. Halogens are notoriously energy hungry, the most common size people have in their homes is typically 50 Watts. I also find they generate a large quantity of heat during operation compared to normal bulbs. They do provide very good light levels (1000 Candlepower) which is great but I have seen rooms that had as many as ten recessed PAR16 Halogen fixtures, the total power consumption of the lighting in such a space would be 500 Watts which in Ireland translates to 12.4 cents for every 2 hours they are activated. Compact fluorescents are one solution but are quite large and so not suitable for recessed lighting fixtures.

Theses LED banks on the other hand are designed to fit the GU10 fitting used by PAR16 Halogen bulbs, the consist of 20 high power LEDs (Light Emitting Diodes) consuming only 1.8 Watts in total and 2 Watts max. They have a mean time between failure of 30000 hours compared to 3000 hours for Halogens and a very low heat output. They do cost most but do the math and figure out the savings you can make over several years (Find out the cost of electricity in Kilowatt Hours its usually on your bill, and calculate how many hours it would take an appliance to add up to 1 Kwh). They are also available in a variety of colours.

Other things you should know about Halogen bulbs are that you should never touch them as the grease from your fingers shortens their lifespans (It does not tell you this on the box, I wonder why) and when they fail they often trip your MCB (Miniature Circuit Breaker) leaving you in darkness.

Here are the technical data sheets for Halogens.

I cannot seem to find a decent data sheet (Apart from the basic one on the Farnell website) for the LED bulbs but each super bright LED is equivalent to 200 candles now multiply that by 20 and the total light from each bulb should amount to the equivalent of about 4000 candles.

LEDs have been gaining in popularity in the world of lighting over the past few years as energy becomes more and more expensive, for example check out this stylish LED Lamp by Herman Miller.

There are many suppliers of these devices but I find the best place is Farnell as they are international and provide very fast service and great technical feedback.

You wouldn't happen to know the Ikea part number for those bulbs, would you?  I live far from an Ikea store, but my brother will be making a trip there soon enough and could get me some of the bulbs if I had the specifics he'd need to find them.

Ikea has these. We're using them in the kid's reading lamps (a LOT less hot than haolgen!)

Its true Bruno as people buy more and more of this type of device the price will come down my only worry would be in the realm of planned obsolescence where manufacturers will be reluctant to produce products containing these components with their current long life spans, after all its very difficult to sell lots of bulbs if each one lasts in excess of 10 years. Also I've worked in this industry and I know the electronics giants intend to suck every ounce of life out of current technologies before retiring them no matter what the cost is to the consumer or the environment. I know products exist (Fiber optics, GaAs Hexagonal LEDs, Sun tunnels etc.) that could revolutionize how we light our homes but demand is not there because the average person does not know about them and so does not demand them. I hope this is changing and hopefully Curbly can help to raise awareness. Also thanks for the NPR link.

My understanding is that as LED lighting options come down in price, they're going to totally revolutionize the lighting market. Here's a good story I heard on NPR about the topic.

That's exactly the kind of bulb I'm looking for!  My whole house uses compact fluorescents, with the exception of the fixture in one hallway.  It uses halogen bulbs and they generate so much heat they feel like lasers.  I've been toying with the idea of replacing the whole fixture with something that can use a CFL, but those LED replacement bulbs might be a better option.
