G4 Base 12 Volt, AC-DC SMD White LED. 288 Lumens. Many RV and under-cabinet lighting fixtures use an 18 or 25 watt halogen bulb with a G4 base. Also, some outside yard lights have this size (G5.3 base bi-pin for example). We think that this LED is a direct replacement only using about 1/10 of the power. This LED module has 18 surface mount LED's that are super bright. For just under the size of a nickel in diameter it produces a massive amount of light. This module can be used in just about any low voltage application because of its small size and brightness. It can be powered by nearly any 12-volt source. Available in the "Daylight" white as shown here (5500K) and, the "Warm" white which looks like incandescent color temp (3000K) elsewhere in my site.
Also, this bulb works for all type of 12V Transformers. It will even fire-up on a 9V battery! Can be hard-wired in or used with some desk lamps as well. cooler running too! Widely used in ships, advertisement boards, outdoor lighting bollards and desk lights. Does not "burn-out", nor gets super HOT. In fact it should last you 10 years or more with nightly use! ** actually is only 20mm in diameter and 30mm tall.
