I replaced all NON-DIMMABLE lights in my RV after a recent solar install with these and found the price/value to be exceptional considering other options. They work great. Now will look at replacing my dimmable lights with similar LEDs. Not sure if these would work or not and have flicker problems. Only issue I had is some of the fixtures in my coach have a vertical pin pattern where these have horizontal but where I had horizontal pin plugs, I used these with great results. A lot "whiter" color than my previous halogens which I replaced. ### ⭐⭐⭐⭐⭐ These are what puck lights should have always had in the first place. *by B***F on September 2, 2015* These little beauties are awesome! Replaced standard 20W halogen under cabinet puck lights with these. Slotted right in and even left in the reflector. Almost no heat, worked with the existing transformer and gave MUCH better light. Brighter, whiter and just MORE of it. Recommend highly. ### ⭐ probably more like 1000 because I don't change out until both go ... *by M***G on May 4, 2018* I've gone through 4 of the 5 LEDs already. They don't last very long at all. I use them each night for may 2-3 hours per night. So in under 3 years have burned out 4, using 2 at a time. That figures out to be less than 1200 hours of usage, at the most, probably more like 1000 because I don't change out until both go bad. I notice they don't give you an hourly rating on these. I won't be buying more, I'll try another brand. ## Frequently Bought Together - HERO-LED SG4-9T-WW Side Pin G4 LED Disc Halogen Replacement Bulb, 1.8W, 15-20W Equal, Warm White 3000K, 5-Pack(Not Dimmable) - RAYHOO 10pcs G4 LED Bulbs JC Bi-Pin Base Light Bulbs 3W AC/DC 12V 20W-30W T3 Halogen Bulb Replacement Landscape Bulbs(Warm White 3000K) - TAIYALOO G8 LED Bulb Dimmable 3W Equivalent to G8 Halogen Bulb 20W-25W, T4 JCD Type Bi-Pin G8 Base, AC 120V G8 Bulb Warm White 3000K for Under Cabinet Light, Under Counter Kitchen Lighting (10 Pack) --- ## 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.co.uk/products/17290347-sg4-9t-ww-side-pin-g4-led-disc-halogen-replacement](https://www.desertcart.co.uk/products/17290347-sg4-9t-ww-side-pin-g4-led-disc-halogen-replacement) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-01*
