SG4-12T-WW Side Pin G4 LED Disc Halogen Replacement Bulb, 2.4W, 20-25W Equal, Warm White 3000K, 20-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.

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.

Flickering way too much to tolerate. I have under-cabinet "puck" lights. With one bulb in, it was OK. As soon as I added more, the flickering began. Tried combinations of different bulbs in the package, to see if it was just one bad bulb, but it wasn't.I've had good luck with the Satco S9542 series bulbs, which run about $9 each, and no luck with any of these cheaper "5-7-8 bulbs for $15-20" crap-packs (the ones where, instead of one large yellow element that lights up like the Satco, the picture shows 6-9 or more smaller yellow elements--see photos to compare). I guess, given the long life of LEDs, going forward I'm just going to buy the more expensive ones I know work, and figure if they last 5-10 years as they should the cost per bulb is not really an issue.Rated a 2 since as single bulbs, they seemed to work OK, but not with multiple bulbs on the same circuit. For that, I'd give 0-1 stars

One out of 20 didn't work. We contacted retailer, has said he will replace but haven't received yet...will updateas for the other 19, they are perfect. I took the advice of the other feedbacks on this item...to go with the lower count LED'sThe light is a touch brighter than the other bulbs but not enough to not tolerate. Still gives a nice ambient light but bright enough to read by if needed.As long as seller lives up to his agreement to replace the one bulb, we will be happy campers and will buy from them again to replace move bulbs

After 50+ of these for our 2011 coach, we finally finished replacements, much brighter, much, MUCH cooler and energy efficient than the halogens !

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.

Just installed them yesterday and they are perfect. To make them perfectly center we cut the prongs a little but they work without the trim. Looks fe the daylight color. Bright but not glaring. Now we have to buy 25 to 40 more to completely change out our motor home. They stay nice and cool.Just bought 10 more to add to the motor home. Uses less electric and brighter!

I dislike really white (5000K) "daylight" lamps and usually buy 2700K-3000K bulbs. I bought these 2700K LED's which HERO calls -WW27. They are too yellow for me. I have no way to measure color temp, but these look more yellow than competing 2700K products. They work, but wish I had bought the HERO -WW (3000K) version instead.In any case, they arrived quickly and installed easily.

Lights flickered and not turning on consistently.
