New LED lamps
« on: June 10, 2009, 09:19:51 am »
International lamps ltd. have recently introduced some new 12 volt LED lamps intended to replace halogen MR16s.

They are the brightest that I have yet seen, and approach a 12 volt 50 watt halogen, available in "white" which I estimate at about 6000K and warm white, about 2,700K.
?17 each though!

( I have no connection with the above firm)

Yep, LED's have taken off enormously here in the last year or so.

We stock 12V 5W GX5.3, 240V 5W GU10 (Both real equivalent to 50W Halogen in both size and light output) and even more interesting 2ft, 4ft and 5ft LED 'flourescent' tubes at 10W, 20W and 30W each.

I have datasheets on all of them if anyone is interested.

Ohh and by the way, International Lamps source their LED's from us :)

Many inferior LED lamps are on the market, with poor light output and a shorter life than halogen.
This has given the rechnology a poor name.

Many customers wont pay ?17 for a lamp, despite it saving more than that.

LEDs are destroyed by heat and are not advisable in enclosed fittings or hot places.

The lamps refered to above are not dimmable. (the 12 volt ones can be dimmed with a variable voltage DC supply, but such use may invalidate the warenty, and they cant be dimmed from a standard dimmer)

I agree however that in a great many cases LED lamps could be used and are not

I totally agree, LEDs have not been helped by the release of poor quality lamps that didn't do what they claimed.

Hopefully now that much better versions are available, more people will take the plunge and try them again and start to reap the benefits.

I guess it is mostly the 'other' components that are causing early failure of leds... can the be repaired?

Another problem is that they are sensitive to power surges, in areas with a lot of thunderstorms surge protectors get fitted to power circuits to protect electronic equipment... but not the lighting circuits!
