LED G9 bulbs.

ThisIsWeird

Hi.

I chickened out of replacing mil's G9 halogens with LEDs as I knew that any difference in light colour would be picked up on... So, got a bunch of Eveready Halogens for the job. Reputable make, I thought.

Well, these wee blighters have been popping at the rate of one every few months, and are a sod to replace, being tucked inside a slim glass shade where sausage fingers are not made welcome.

So, LEDs it's gonna have to be. 

Could anyone recommend an LED equivalent, please, that matches 40W in both output level and colour, ideally one that they've used themselves and are happy with? Non-dimming is ok.

Thanks.

Meanwhile, I hope y'all have a lovely, peaceful Chrimbo, and more success in accessing your local pub than Santa did in Weird Giffard.

Just a word of caution, the cheap Chinese Ebay specials can melt the little PCB with the LED's and give off smoke and a nasty electrical burn smell. Not a good cost saver at all. Who knows what would happen if not switched off at that point.

Thanks. I'm looking at decent makes, like Philips - money no object (mil paying...) 

If a bulb fails, my 'reputation' would also go in a puff of smoke

I got these for some lights over my dining table - https://www.amazon.co.uk/gp/product/B08HTZ41R1/ref=sw_img_1?smid=A3P5ROKL5A1OLE&th=1.  They're a decent brightness and colour, matching other warm white bulbs in the room fine.

Energizer - stupid cheap. But is 2700K too warm?

Thanks - good to have a real-life experience.

'Decent' and 'fine' - damned with faint praise! Kidding

Do you reckon they are full halogen equivalents? A full '40W' brightness, and nigh-on halogen colour? 

Cheers.

stick to warm white 3000k colour. The closest you'll get to the mains halogen ones you are replacing.
I used to sell lamps (not bulbs!) to the wholesale trade.

I've never had G9 lamps before because I avoided anything that only accepted halogen due to the running cost so can't compare.  However a quick search suggests a 60W halogen could achieve as much as 900 lumens, where as the bulb I linked does 570 lumens (but claims 60w equivalent).  I got these to replace some cheaper Wessex bulbs I got from Toolstation, which I think achieved only 450 lumens and they were far too dim.

What exact wattage / brightness (lumens) and colour temperature are you looking for?

In March I got these ones https://www.amazon.co.uk/gp/product/B08CBYTR83/ and have them in a relatively little-used reading lamp and the downstairs loo... both are 'enclosed' in the luminaire.  They are close to incandescent lamps in terms of colour temperature, but are not very pretty to look at.

Similar looking g9s (5 off, no name or rating visible on them) are in a bedroom chandelier and are well over 8 years old as we inherited them with the house purchase.

Some leds may (will) be longer than the halogen lamps so measure to check if they will fit the luminaire.

All these led lamps are now made in China and I'm not sure Brand Names are any indication of quality and performance any more?

Thanks everyone.
I'm looking for the nearest equivalent to 40W halogen capsule lamps - similar output level and colour.
The surrounding shades are frosted and long, so that ain't an issue - it'll hide 'ugly' and long LEDs.
Halogen is seemingly circa 3kK, but warm white LEDs are typically 2.7?
Is that close enough?

Back in the day TV camera line up was done at fader 7 and for 2700 Kelvin from the mostly Tungsten Halogen studio lamps that were 3200K at full voltage.  The colour temperature difference from lower fader level say 2200K to 3200K was not significant or noticeable as the incandescent filaments were broad spectrum of the wavelengths of light.

LEDs and Fluorescent and Discharge lamps are not broad spectrum in the same way and can have 'spikes' of particular colours.  The missing wavelengths and/or relative levels of the wavelengths in the light source can make objects seem 'oddly coloured'.

Thus, the Colour Rendering Index CRI of LEDs is far more important.  Incandescent lamps have a CRI of 100.  The LEDs I've linked to claim 85 which is not at all bad.

Cooking / foods seem to show up dodgy CRI leds to my eyes at least.

I suspect that CRI claims and the proof of the pudding will require on site testing by the M-i-L's eyeballs. Good Luck!
