Review: Great Little Bulb! - 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!!! Review: Beware it is on the bigger side - 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. ## Features - 5 pcs T3 G4 Base Bi Pin JC LED Halogen Xenon Replacement Bulb - 2.4W Consumption 25W Equivalent 250 Lumens LED G4 Replacement Bulb - For use in Ceiling Lights, Pendant Lights, Desk Lamps, Table Lights, Puck Lights, Under-counter Lights, Closet Lights, Under-cabinet Lights - For use in Accent Lights, Display and Landscape Lighting, and other Applications. - Not dimmable, don't work with dimmer switch.

Thank you for a great product!!! ### ⭐⭐⭐ Beware it is on the bigger side *by R***I on July 18, 2017* 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. ### ⭐⭐⭐⭐ Good replacement for my under-cabinet 20w Halogen puck lights *by M***K on October 14, 2016* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/39941362-sg4-12t-ww27-side-pin-g4-led-disc-halogen-replacement](https://www.desertcart.be/products/39941362-sg4-12t-ww27-side-pin-g4-led-disc-halogen-replacement) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-10*
