We stock all sizes of MR bulbs, from the most common MR16 to the less frequently used MRs like the MR14. Ushio’s MR14 bulbs have G7.9 or GX7.9 2 vented pin bases with 3,350K and 3,400K color temperatures, giving these bulbs a clear white light. The MR14 differs from the MR-16 with regard to the bulb’s diameter. The ‘14’ and ‘16’ correspond to 14/8 of an inch and 16/8 of an inch, meaning that an MR14 is 1.75in in diameter. MR14 bulbs are used in a significant range of applications from medical equipment, projectors, and more, so if you having lighting needs in these fields the MR14 may be for you. If you need this specialty bulb or other specialty MR bulbs we likely have the one you need and at a great prices too!
