Relamping with LED
I have a ceiling fitting with G9 bulbs - Halogen 40 watt.
The heat and a bit of arcing has damaged a lampholder and I can't work out how to replace it. Ideally I would like to go with LED - but dimmable ones are not bright enough. I was wondering if there could be a way to rebuild it with a power supply in the ceiling and low voltage LEDs in place of the G9s. Are there any low voltage LEDs that are brighter than the halogens in a similar size? |

I was wondering if there could be a way to rebuild it with a power supply in the ceiling and low voltage LEDs in place of the G9s. Are there any low voltage LEDs that are brighter than the halogens in a similar size? This was covered - more or less - in the recent thread "Where to buy G9 LEDs, i.e. reasonable price and quality?" Basically, if your ceiling fitting was designed for use with G9 halogens, you might well find that LED bulbs overheat in the same fitting, and give a lot shorter life than you expect. In general, too, the lumen figures quoted for LED G9s are, shall we say, somewhat on the optimistic side! That being said, if you could get G9 low voltage LEDs you should find they are more reliable than mains G9 LEDs, as it is usually the power supply circuitry in the base of the bulb which fails through overheating rather than the led module itself. The problem is that, as far as I can see, all G9 bulbs are mains voltage! So if you need a power supply and something different from G9s, why not replace the light fitting and stay with a mains voltage LED bulb? GU10s, in my experience, are more reliable and brighter than G9s, and there is a vast choice of ceiling fittings for GU10s. -- Jeff |

Now according to people I talk to, its not that leds are less bright than halogens, but the light is different in quality. It is often described as stark or stressful, but maybe somebody can tell us why. Mine arent when set to warm white. Is it perhaps because the leds used tend to have discreet colours mixed to make it look like white, but there are key frequencies missing, much like those low energy lamps they used to give away. So did fluoros but only an idiot claims they are stark and stressful. wrote in message ... On Sunday, 8 March 2020 21:48:47 UTC, John wrote: I have a ceiling fitting with G9 bulbs - Halogen 40 watt.

NT Most LED lamps now on sale are actually constructed using near UV LEDs coated with a broadband emitting phosphor - the yellow - orange bit you see. |

Are there any low voltage LEDs that are brighter than the halogens in a similar size? Weve several lights which use 2 x G9 40W. While they are fine heat/arcing wise ( the bulb holders are ceramic) they are terrible life wise. Ive tried a few LED replacements which claimed to give an equivalent or higher light output but none were even as good. All were 240V. Im still hoping to find some, meanwhile I have a stock of 40W G9 bulbs and a ladder handy. As for the lamp holder, our G9 holder is secured by 2 small screws, visible from the bulb position on some and the reverse ( back) on another one. You can buy ceramic fittings on EBay. |

Yes the plastic holder go brittle with age in any case. Not needing light
these days means I don't really have a view, but there do seem to be a lot of people moaning about lights of late. Brian -- ----- -- This newsgroup posting comes to you directly from...

I think they choice of colour depends on the environment. In a kitchen or a
study where we need plenty of light and/or don't want it to be too restful, we've got daylight white. In bedrooms and the lounge, we've either got warm white, or else Philips Hue which can be set to a range of colours. The shades of white from normal Philips Hue make a lot of sense: they go from candle white (yellowish) to daylight shade (quite blue), with normal warm white and daylight in between. I'm not sure it's worth spending extra to get colour Philips Hue which have a much wider gamut of colours, ranging from neutral white to very saturated colours. The one problem with dimmable LEDs (certainly Philips Hue, and maybe other ones) is that the dimmest setting is actually quite bright, if you want a night light that can be left on to guide someone to the loo at night without keeping them awake. I'm not sure why it's not possible to reduce either the current (for non-pulsed LEDs) or else the mark:space ratio (for pulsed full-on-or-full-off LEDs) to make the light go even more dim. One day when I can be arsed to do it, I'll measure the range of brightness in terms of "stops" on a camera. "Brian Gaff (Sofa 2)" wrote in message ...

I'm not sure it's worth spending extra to get colour Philips Hue which have a much wider gamut of colours, ranging from neutral white to very saturated colours. Specially if you always use the one color and just want to be able to select it very easily when setting it up initially. The one problem with dimmable LEDs (certainly Philips Hue, and maybe other ones) is that the dimmest setting is actually quite bright, if you want a night light that can be left on to guide someone to the loo at night without keeping them awake. That’s trivially fixed with a movement sensor because you can specify when it only uses a low level that you can still see by, by time of night so you don’t get dazzled or wake anyone else up. I'm not sure why it's not possible to reduce either the current (for non-pulsed LEDs) They are in fact pulsed and you can see that by wagging your finger between your eyes and the bulb with bulb on. or else the mark:space ratio (for pulsed full-on-or-full-off ? LEDs) to make the light go even more dim. One day when I can be arsed to do it, I'll measure the range of brightness in terms of "stops" on a camera. "Brian Gaff (Sofa 2)" wrote in message ...
