SG4-12T-WW27 Side Pin G4 LED Disc Halogen Replacement Bulb, 2.4W, 20-25W Equal,Warm White 2700K, 5-Pack(Not Dimmable)

Just replaced the 51 Hallogen light bulbs in our 2004 Monaco Dynasty Diamond IV and couldn’t be happier. I can actually see at night! The light out put is awesome. We went with the bright white lights in the living space and then changed out the bedroom lights with warm white bulbs from a different manufacturer. I like the HERO-LED light bulbs much better than the other brand. Why? The bulbs were much easier to install as they are super slim discs with some compositors on the back side. They fit perfectly in our ceiling mounted hallogen puck style lights with round glass lenses. The other brand of warm white bulbs have a large plastic dome on the back/top side and are really too thick to install and keep the glass lenses in place. There is only one disappointment so far from installing these new LED bulbs. It sounds odd, but we are camping this weekend farther from local TV broadcasting towers and we are in the fringe coverage areas. Signalsckme and go on some chanels. OK, so here’s the weird thing.....if we turn off the LED bulbs, we get TV signal. Within 3 secs of turning them back on we lose signal. This has occurred over the past 4 days and always happens. I share this because these LED bulbs obviously give off some type of interference that impacts Digital over the air TV signals. Kind of scary.

They are slightly big and may not fit may of the existing under cabinet lights. I had to come up with a creative way to make it work for me. Luckily it was easy and not a hazard. But the light is very good and bright and daylight. So you will see the right colors and contrast.

Bought these to replace motorhome halogen lights. Great price, but of the five lights only two worked. I paid $15 for one light at Camping World so I hoped these would be similar.... Not so much.... Complained to Amazon and they promptly shipped another set - these arrived and all 5 worked. I verified the three were still not working but am very happy to return them and have five working lights!

The light output is amazing for only 2.4 W . The color is perfect for replacing incandescent bulbs. Apparently my bulb sockets were small because I had to remove the reflectors but it doesn't matter because it doesn't need reflectors . The ceiling in my RV salon has 12 lights and after running the incandescents for about five minutes the fan would come on in the power distribution box and was somewhat annoying . Now the lights use so little power the fan ever comes on . I can also shut off the generator earlier in the evening without any concern or running down the batteries .

What a great little bulb!!! I have numerous round, recessed lights in my RV that were originally Halogen 40w Bulbs. The glass lens would get very hot along with the wall switch that turns them on. I purchased some other 40 LED Warm White bulbs of the same design but it appears that they are no longer available in the round shape. I was a little concerned that these being rated at a 20w equivalent may not put out enough light. Boy was I surprised!! These little lights are the perfect size for both the 40w and 20w Halogen recessed light fixtures and give out plenty of comfortable, warm white light. No more hot glass lens or wall switches!!! Each bulb came in its own little box and then five (5) bulb boxes placed into a larger box for shipping. All of the bulbs I purchased worked as designed. And, no polarity issues!!! Plugged them in and they all worked great. Thank you for a great product!!!

Hard to recommend if I have to send them back because of flickering lights. Product description says to not use if using an electronic transformer. Well, how the hell do I tell that? I'm replacing halogen lights in a showcase and it should work. If they didn't flicker, the bulbs have good brightness, fits a normal G4 base.

I ordered these as a 5 Pack. They arrived promptly on Amazon Prime. All 5 Bulbs worked as decribed. They replaced my old Halogen bulbs which got very hot. These run much cooler. The reason my rating is low is that I installed them into an undercupboard Puck style cabinet fixture. My smaller halogen bulbs fit in no problem, but due to the size of these LED bulbs 1 of the tabs does not secure the bulb up all the way into the cabinet fixture.. There is also a bit of flicker, especially when turning on initially. If there was a better LED that was Dimmable, with Daylight 5K lumens I would buy it and avoid these bulbs.

These LED's replaced some T3 G4 12v 20watt halogen side-pin bulbs used in the puck lights under my kitchen counter. The 20w halogens are rated at about 300 to 350 lumen and put out a slightly blueish light... very white. These LED's were slightly less bright, maybe because they're 2700k and are more yellowish. The brightness is acceptable. But if I were to do it again I'd get a brighter wafer light. I'm getting old and need more light when I cook. But, again, the brightness of these is acceptable. The one thing to note is that these side-pin G4 LED's fit nicely into my 1998 puck-style under-cabinet lights. That's something I just wasn't able to ascertain when searching for a replacement bulb. Anyway... they fit and they work.
