Features: Base: G4 Bi-Pin Base / 4mm Pin Shape: T3 Tubular JCD Diameter: 1 cm. Length: 30 mm. Power: 20W Dimmable: Yes Beam angel: 360 degrees Voltage: 12V AC/DC Color Rendering Index (CRI): 99+ for vivid, enhanced color Tips: ♦ Make sure the bulb base matches your lamp base. A common confusion is with G8 2 pin bulbs because they look very similar in the photos, but the G4 has a much smaller distance of 4mm rather than 8mm. Please check your pin distance before ordering. ♦ Dimming with LED only dimmers will result in incompatibility, as LED dimmers work very differently. Please check the compatibility of your dimmer switch or lamp before purchasing.
