The conventional 50W MR16 halogen spotlight used for indoor display illumination produce a warm orange colour (2700K - 2800K) and consumes alot of electric energy. Their operation temperature easily pass the normal acceptable level and if you are not careful, you can get scorch by it. Today's conversion is on the popular MR16 halogen spotlight. The size of the MR16
spotlight is 51mm (diameter) and it has a quartz-halogen bulb that will usually operates for close to 2000 hrs. It has a special cover glass to minimise the UV rays and also provide protection for consumer against bulb rupture explosion.

We were asked to replace 20 units of 50W MR16 halogen spotlight in the effort to further reduce the
electricity bill of this organisation. These halogen spotlights were used in display cabinet and along one side of the ceiling as track lighting to illuminate a huge wall painting. The replacement LED spotlight is only using 3W, lots of difference in terms of energy savings!
This is the new 3W LED spotlight (above picture), it will replace the old 50W halogen track lighting fixture (below picture)
Both new and old spotlights in actions (picture below), we have chosen 2700K for the LED spotlight to match the original spotlight colour and the brightness of both lighting look similar. We could feel the growing heat of the conventional MR16 halogen spotlight after it was switch on for less than 10 seconds, it is unbearable to stand within the vicinity of the MR16 spotlight beam area. The operating temperature of MR16 halogen spotlight can reach 200 degrees celsius!
Retrofitting of the MR16 spotlight within the display cabinet is quite straight forward and fast. If you plan to DIY, please do it only with trained/ approved electrician present. The MR16 halogen spotlight uses an electronic transformer which converts the 230 volt to the low operating voltage is removed and replace by the new LED driver to support the operation of the 3W LED spotlight.
At the end of the conversion, we were please with the performance of the new LED spotlights. We look forward to facilitate energy conservation with the use of energy efficient luminaires. The total energy use now for display illumination is 60W (20x 3W LED spotlight), it is slightly more than one 50W halogen spotlight. Thank you.
