Although the GX53 lamps seem good, there is no question GU10 has become a standard.
If you look at Lidi smart lights they had E27, E14, GU10, and a colour changing strip. You could not even buy the B22d lamp which has been for years the British standard light bulb.
I had a kitchen with a 65 watt fluorescent lamp, 65 watt fat tubes were replaced with 58 watt tubes, and due to wrong ballast it was a bit poor starting, so I as a quick easy cure fitted a 24 watt LED tube.
The drop from 5200 lumen to 2200 lumen (24 watt) was not too noticeable, although first LED tube was short lived at 18 months.
My son now lives in the house and he swapped the LED tube for GU10 lamps 16 x 3 watt (48 total), 230 lumen (3680 total) the light is not improved, but it does look better.[attachment=1]Kitchen bike.jpg[/attachment] But what you need to remember that is a high ceiling. With LED the heat is not really a problem, although surges can be, last house lost one LED 5 foot fitting, this house non, and this house has a surge protection device fitted.
LED lights have worked well for me, others I see complain about short life, biggest problem for me is flashing and flicker, there is nothing on a LED bulb to say if a smoothing capacitor is fitted, it is pot luck, however the LED tube to replace the fluorescent in the main does not require one to remove the wire wound ballast, so they have a massive voltage range, the only way to get that range is to use a pulse width modulated driver, so the fluorescent tube replacement is likely to have less shimmer to a GU10.
To fit smoothing capacitors needs space, so a BA22d or E27 bulb is less likely to shimmer to a G9 bulb.
My wife got G9 in the bedroom [attachment=0]G9-comp.jpg[/attachment] the small bulb allowed the covers to be fitted, the large one did not, but the large one no flashing or shimmer. One of the large ones failed, and I opened to see how made, actually found the fault a dry joint, and running again, but the smoothing capacitor inside that bulb is nearly the size of the whole small bulb, so big is good.
