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.

Problem 1 / Energy waste
95% less electricity

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.

1W vs 20W Saves €15+ per bulb/year
Instant payback
Problem 2 / Eye strain & flicker
Flicker‑free comfort

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.

IEEE 1789 certified No visible/invisible flicker
Easy on the eyes
Problem 3 / Frequent replacements
30,000 hours lifespan

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.

30.000h vs 2.000h ~10 years (8h/day)
Maintenance‑free
Bonus / Dangerous heat
Low heat, safe to touch

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.

70% lower surface temp No UV/IR radiation
Safer for home & commercial use
