The Moonrays 10-Watt Halogen Bi-Pin Replacement Light Bulbs are compatible and ideal for 12-volt Low-Voltage landscape lighting. This 2-pack of clear 10-Watt, 12-volt halogen bulbs have an average lifespan of 3,000-hours, have G4 base, 1 in overall length (33-millimeters) and have a 125-Lumen rating. These JC Type halogen light bulbs are Low-Voltage halogen capsules with pins on the base. These bulbs will burn longer without sacrificing light output, display crisp white light, provide excellent beam control and offer high-Lumen maintenance. Try to handle halogen bulbs with a cloth rather than bare hands. The oils on your fingers can cause a "hot spot" on the bulb that gets hotter than any other part, causing premature bulb failure. For best results, make sure to replace your bulbs with the same size and style of bulb that came with your original Low-Voltage light. Let Moonrays help make your outdoor settings as beautiful, livable and enjoyable as any room in your home. The Moonrays 10-Watt Halogen Bi-Pin Replacement Light Bulbs come with a 1-year limited warranty provided to the original purchaser, which protects this product from manufacturing defects in material, assembly and workmanship.
