What this bulb is and who it suits

This Antique Light Bulb Co. MR16 halogen bulb delivers a green-coloured spot beam for accent lighting. It runs on 12 volts and draws 50 watts through a GU5.3 two-pin base. The 12 degree beam angle makes it suitable for track lighting, display cabinets or garden features where a focused coloured wash is wanted. It is not intended for general room illumination or for fixtures that require a wider flood spread.

Heat, noise and power in use

The lamp operates at 50 watts on a 12 volt supply, so the fixture and transformer must be rated for that load. Halogen capsules run hot; the front glass and dichroic reflector direct much of the heat forward, so allow adequate ventilation around the fitting. There are no moving parts, so the bulb adds no audible noise to the installation. Rated life is 3200 hours under normal cycling.

What the included glass and reflector change

The frost glass finish softens the edge of the 12 degree spot without widening the beam. The dichroic reflector passes infrared heat forward while reflecting visible light, which helps protect heat-sensitive objects in the beam path compared with a standard aluminium reflector. The green capsule colour is integral to the glass, so the hue remains consistent throughout the 3200 hour rated life. No separate filters or gels are required.

Questions about this item

How do I install this 12 V MR16 halogen bulb without touching the glass?

Turn off the power, let the fixture cool, then hold the bulb by its ceramic base and push the GU5.3 pins straight into the socket until they seat. Skin oils on the quartz capsule create hot spots that shorten the 3200-hour life, so wear clean gloves or use a cloth.

When will this 50 W green MR16 need replacement?

The rated life is 3200 hours. At typical track-lighting use of four hours per day, expect to replace it after roughly two years. Frequent on-off cycling or voltage above 12 V will reduce that interval.

What limits continuous running of this 12-degree spot bulb?

The dichroic reflector passes heat backward, so the fixture must dissipate the 50 W load. If the housing or transformer overheats, the bulb will cycle off or fail before the 3200-hour rating is reached.
