What is the purpose of gu24 base bulbs? « on: September 09, 2023, 05:57:17 PM » Author: Robotjulep
Why are newer homes using gu24 base sockets and lamps? It seems like they are not backwards compatible with incandescent or halogen. They only work with CFL or LED. Also, they cost more than their e26 counterparts. Does anyone know why? On side note: It makes these gu24 bulbs very easy do use without a lamp holder. Simply solder on wires to the gu24 base bulb and you have an integrated light.

You answered your own question !  Their purpose is to prevent you from using non-energy efficient lighting such as halogen or incandescent !

GU24 sockets and bases can burn in hell for all I care. They're such a pain in the you-know-what to find what variety you want, even with LED and CFL; when GU24 lamps can be found, they're only available in a few wattages and color temperatures. Also, they're huge, so, a lot of the time, they won't even fit in an enclosed fixture. Not to mention that they'll stick out of an open fixture, such as a wall sconce. Rant over.

I recently bought a Panasonic bathroom fan/light combo from ReStore that uses a GU24 R-30 LED flood . I plan on installing a normal medium base socket so I can run what I want ! The supplied lamp is extremely dim !

How many watts can a GU24 base handle?

I think the highest I remember seeing in a CFL was 23w , 100w equiv. . I may be wrong though

I thought GU base lamps are only for preheat fluorescent starters, but these gu24 ones in particular, are rather useless.

https://www.lighting-gallery.net/gallery/displayimage.php?album=5209&pos=0&pid=228499  It's listed as 720 lumens but it's not even as bright as an incandescent 30R20 !!   You can also get GU based MR-16 lamps .

Recently, I got MR-16 halogen can lights from a restore. They use a ceramic base instead of a plastic base. Too bad they never made any PAR-30 or PAR-38 GU-24 halogen floods.

So manufacturers do this everywhere? Just because consumers like the price of incandescent more than CFL or L*D, manufacturers try to force them to buy their stuff by changing compatibility. That is rather sneaky.

Design wise, the GU24 base socket seems like it is a good design. The bulbs are easier to put in or take out in an enclosed space, and the live terminals (and the lamp base when inserted) are shrouded so that you can't touch them. But unfortunately they used them to force "energy efficient" lighting technologies on us. Another thing that people didn't like is there was no version for 3 way lamps, but the designers probably could have added that by adding another version to the standard with a pin in the middle. So overall in my opinion it is a decent design with a wasted potential. If they had designed it with the intention of being a better lampholder and made all lamps in the GU24 base format (including incandescent and halogen) and had not used it to force people to use CFLs and LEDs, then I would like it.

Not to mention that they'll stick out of an open fixture, such as a wall sconce. When I have seen GU24 base fixtures in the wild, I have never seen lamps sticking out or not fitting. They are actually shallower than an E26 socket, and since they don't need to be screwed in, so they are quite practical for enclosed fixtures.

But this is definitely true.

Well, the lighting industry is going from glass to plastic, unfortunately. Also, quality control is not very good either. Occasionally, there is a good L*D lamp but that doesn't often occur.
