This replacement low voltage LED MR16 spotlight bulb from Crompton Lamps sports a full glass body, allowing it to resemble a halogen MR16 spotlight while using a fraction of the energy.Where a halogen MR16 might use 35W to produce 400lm, this LED replacement 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 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.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.
