Default G9 Bulb Replacement Qs

Hi all

I have a light fitting in the hall which I am quite happy with.
The down side is that bulbs keep failing.
It takes push in G9 clear 40w bulbs which are housed in frosted
glass "shades" 38mm inside dia.

The questions a

Would LED equivalents be more robust/last longer?
I prefer brighter light these days - can LEDs produce decent white
light?
Which suppliers are recommended for quality?

Thanks

G9 leds are inherently not as bright a G9 halogens (yet?). They might
quote a high lumen output on the pack, but IME they have often only half
the brightness of a halogen, You won't get anywhere near the light
output of a 40W halogen, even with a 6W led: - 630 lumens vs 330 (- 700*
see below) lumens.

Depending on the design of your shade, they are liable to suffer from
overheating. If the shade points down, or partially down, and there is
no ventilation hole at the base, heat will build up around the base of
the led G9 where the electronics are. Heat and electronics in a G9 do
not go together well.

A couple of years ago I replaced 12 G9 halogens (42W) with supposedly
brighter 4W leds. They were nowhere near as bright. And a couple have
already gone south.
