Its silicon body replicates the size and shape of halogen capsules, and its G4 fitting retrofits to existing light fixtures, making it simple to swap out your old bulbs. The 25,000 hour life of this LED capsule is far in excess of its halogen equivalents, offering a long lasting, reliable source of light that will not need replacing again for years.Please note that this product is not suitable for dimming and is for indoor use only.4000K cool white220 Total lumens2W (Halogen equivalent 10W)25,000 Hour rated lifeClear silicon bodyDimensions: Diameter = 11mm, Height = 39mmPlease note that theis light bulb will operate with most AC and DC 12V transformers.
