Product Details: – These bulbs known as G4 / Bi-Pin base bulb, and are typically used in low voltage lighting applicatons. – This product has good color rendering performance, long life, small volume, good illumination, and the filament is specially processed and not easy to break. Features: – The bubble is filled with high-purity halide to inhibit the evaporation of the tungsten wire. The bubble does not blacken, the light decays slowly, and the axial filament is kept for a long time, which can produce high central light intensity and good concentrating performance. – With reflective lamps, it can control the illumination angle more effectively; any lighting position is more widely used. – Isolation of ultraviolet light, low pressure less than 2.5PA, enhance the protection of the object being illuminated, the lamp does not need front glass. Specifications: – Voltage: 12V – Wattage: 5,10 or 20W – Pin spacing: 4.0mm – Pin Length: 8.0mm – Total Length: 30.0mm – Bulb Diameter: 8.0mm Package Included: – 2/4/6/8/10 x Bulbs Notes: – The colors may be a little different for the different monitor display. – Please allow minor deviation due to manual measurement
