Low voltage halogen equivalent???

[Joe S]

I have a customer who has in excess of 25 low voltage down lights that are on 24/7. They have a condition where they can't tolerate LEDs or CFL lamps and GU10's aren't bright enough. Does anyone know of a make of bulb that runs cooler than most as I am changed lamp holders every 6-8 mths. I've tried all manner of holders and ally backed lamps but in the end the wire burns off the terminal. They are concerned about the reliability of the materials but I have assured them that it is all good bits and that no one usually has their lights on 24/7. The heat generated is huge.

Any ideas greatly appreciated.

P.s
I know the repeat work is great butI would also like to know if there is an answer.

Cheers
joe

That's because you are a cat.

What make LEDS have they tried ? As Andy said previously about strobing effect , noticed it myself on certain types .

Have you ever fitted an Enlite 8w integrated fitting , I find the light to be very halogen like .

Maybe try some different types of LED lamps in a room (but don't tell them they are LED) as it maybe psychosomatic?!

I'm guessing they are wanting a more traditional warm white than natural / cool white light as well?

Have you tried reflecting light off the ceiling, from, say, warm white LED floods?
You could try modifying the colour of the light with filters - rose, yellow, pale blue (daylight), amber, one blue one amber next to each other mixed to make white?
There are also UV filters available which filter out the UV part of the spectrum, if that is the problem, or you could try a clear filter and tell the customer it filters out all the nastiness, or make up a frosted light box with LEDs of a similar CT to tungsten, and simply tell them the light is "sourced organically and ethically".

buy them some bloody candles or install gas lights. unk:

Agree with Andy78 - some people may be more susceptible to the strobe effect. This effect can be seen quite clearly when you are looking at the rear lights of a car which has LED lights - move your head from side to side quickly whilst looking at them nd you can see the effects of the high frequency drivers. (The LED drivers, not the car drivers ). Daz

Do they need to have them on constantly? Some 'down time' for the fittings would obviously help. How about on a dimmer to reduce loading for periods of time. Although I am not 100% as to whether the heat generated would be reduced much at a lower voltage.

I would expect there are some fittings designed for commercial installations that would run 24/7. Maybe call some manufacturers.

You said you tried a similar LED. How about a few different branded LEDs to see if any are acceptable to them.

If you can get LEDs which use a true/pure/ripple free DC supply then you won't get the flicker.
Depending on how much they are willing to spend it would be worth giving a company like photon star a call and asking if they can come up with a suitable driver for their eco600 down lights (which are the dogs danglies of LED d/l in my opinion) or similar. You might find the non-dim able driver with a high quality fitting like the Eco 600 doesn't strobe anyway (but I doubt it as they are all switch mode)

Failing that you could construct 12V linear DC supplies with LM7812s, a transformer and a couple of capacitors to supply MR16 LED lamps which shouldn't need huge transformers to be used.
I don't normally advocate the use of LED retrofit lamps like these, but in this case it might be the best solution.

It is possible to make linear constant current drivers too, but they won't have the efficiency of a switchmode jobby.

If money is no object at all then GDS might be able to help, they make top notch LED lighting for theatre auditoriums and suchlike.
