GY G4 1W LED Capsule
One Small Bulb, Three Big Lighting Problems Solved
Constantly replacing tiny G4 bulbs? High energy draw on your 12V system? Flickering light causing eye strain? The GY G4 1W LED capsule is designed to eliminate these frustrations while fitting perfectly in compact fixtures.
20W halogens drain batteries and inflate bills. This 1W LED delivers 173 lumens while consuming 95% less power. For RVs, boats, or home lighting, your 12V system lasts much longer.
Many mini LEDs flicker imperceptibly, causing tired eyes and headaches. GY's flicker‑free driver ensures stable, constant illumination — perfect for kitchens, living rooms, cupboards, campers, and other compact interior lighting.
Halogen capsules burn out around 2,000 hours. This LED lasts 15x longer — roughly 10 years with daily use (8h/day). Install once and forget about ladders, repurchases, and waste.
Halogen G4 gets dangerously hot, risking burns or fire in enclosed fixtures. Our LED stays cool — safer for under‑cabinet lighting, display cases, and furniture.
Where This Bulb Belongs
Compact G4 bi‑pin design fits seamlessly into tight spaces and 12V systems — homes, campervans, hotels, and more.
Under‑Cabinet
173lm evenly lights countertops. High CRI for true food colors.
RVs & Caravans
12V native. Ultra‑low draw preserves battery for longer trips.
Showcases
No UV radiation. Accurate colors for retail and collectibles.
Closets & Shelves
Instant‑on when doors open. Compact body fits anywhere.
Accent Lighting
Warm inviting glow for sconces, chandeliers, and hotel guestrooms.
