LED v Halogen



We tried to be environmentally responsible by used LED lights in our downlights. But they gave off insufficient light and bathed the area in a cold blue light. We took them back and got a refund. LED lighting is improving all the time, but it is not quite there yet for everything.

    What light output are you trying to achieve i.e. 20W 50W etc and also are you looking for a warm white or a cool white?

    Regards

  2. I've been replacing the globes throughout the flat as they've died with the new energy saving ones and yes, I've got that cold blue light in a few rooms. Trouble was that back then the selection wasn't as good. The only thing I was looking for was to make sure it would fit in the light fitting! Anyway, I now need to wait 10,000hrs or whatever it is until I replace them. In the mean time, it's good to be green!

  3. Please check Google News and search for LED MR16. You will learn about the Toronto (Canada) Palace Pier condominium retrofit project with close to 1300 LED MR16s that have a warm CCT and a CRI of 92+. Product information is available at www.CRSElectronics.com.

  4. Hi Caroline. 50w is what we want. These were marked as equivalent, but they just don't give off the light we need. I do know that they come in different colours and they clearly weren't the right colour as we like warm white.

    Generally Rob, our experience with energy saving lighting has not been good.

    Thanks Brian. There is an agenda for our building to be retrofitted with energy saving lighting. An attempt in the car park with fluoros failed a few years ago as they tubes were not lasting at all.

  5. We have an energy saving globe or 5 around the house. I don't like them, they are not as bright as the others..and I wonder...how much ebergy is used to manufacture these "Non Bright Lights" ?

  6. Quite a bit of energy Cazzie. They have some sort of printed circuit board I believe.

    Hi Andrew,
    Think Lighting Ltd have a new recessed ceiling light in a cool white that gives out an equivalent light output to a 50w downlighter,
    should you wish to have a warm white they do one that is equivalent to a 40w. It is IP67 rated , fire rated and acoustic rated and comes in one complete unit which complies with the new building regs whereby you need a housing over the back of any light that is placed into a ceiling void!

    Visit their website www.think-lighting.co.uk
