This low voltage replacement LED MR16 spot light bulb from Crompton Lamps sports a full glass body and Chip On Board LED technology, allowing it to simultaneously resemble a halogen spotlight while using a fraction of the energy.Where a halogen MR16 might use 35W to produce 350lm, this LED MR16 12v spotlight uses just 5W but emits the same bright, cool white light.It pushes directly into existing GU5.3 bases without any additional rewiring required, making it the perfect retrofit replacement for your halogen MR16 spotlights. Unlike other LED replacement light bulbs of the same class, it also shares the same physical characteristics as its halogen equivalent thanks to a full glass body and COB lens.This ultimately makes the process of replacing your halogen light bulbs as seamless as possible, with shared aesthetics making it virtually impossible to tell the two light bulbs apart and the only noticeable difference being in your substantially reduced lighting bill.This spotlight lamp is fitted with a low voltage 12V GU5.3 2-pin (5.33mm apart) base.This MR16 Spotlight is a newer product from Crompton Lamps and supercedes their old MR16 Spotlight part codes: LMR165CWSMD.Please note that this light bulb will operate with most AC and DC 12V transformers. However, some 12V transformers may have a minimum required load which may not be met when installing low powered LEDs: these drivers may cause flickering or the LEDs not to function correctly. If this issue arises it may be necessary to source a suitable LED driver. Please refer to the manufacturers website for compatibility.
