A suggestion, not a specification. A calculator can get it wrong — have a licensed electrician confirm the driver, the total load and the wiring before you order.
The Domus KEY-MR16-GLASS is a 4.7 W LED globe in the MR16 shape, 12 V DC, with a 60° beam and a glass body, in 3000 K or 5000 K.
✅ It is a direct size replacement for a conventional halogen MR16 — same Ø50 mm face, same 46 mm depth, same two-pin low-voltage base. It drops into the fitting the halogen came out of.
⛔ What it needs is a proper LED driver. It runs on 12 V DC and requires a constant-voltage LED driver, which is not included.
⚠ Your existing halogen transformer is probably not one. An iron-core or electronic halogen transformer is a different device, and driving an LED globe from one is the usual cause of flicker, buzz, or a lamp that will not strike. Tell us what is behind the fitting and we will tell you whether it needs changing — it is the single most common reason a low-voltage LED retrofit disappoints.
4.7 W LED globe, MR16 shape, glass, Ø50 × 46 mm. 12 V DC — requires a constant-voltage LED driver, not included. Output 390 lm at 3000 K or 420 lm at 5000 K. 60° beam, CRI ≥80, SMD, IP20. Fully dimmable with suitable dimmers — the driver must support dimming as well. ⚠ Lifespan 15,000 hrs. Direct size replacement for a conventional halogen MR16. Warranty 3 years.
Supplied and supported by Lights For You.
Yes, physically — it is a direct size replacement for a conventional halogen MR16, with the same Ø50 mm face, 46 mm depth and two-pin low-voltage base. It drops into the fitting the halogen came out of. What may need changing is what is behind the fitting.
Usually not, and this is where most low-voltage LED retrofits go wrong. The globe needs a 12 V DC constant-voltage LED driver. An iron-core or electronic halogen transformer is a different device, and running an LED globe from one typically shows up as flicker, buzz, or a lamp that will not strike. Tell us what is behind the fitting and we will tell you whether it needs replacing.
No — it is sold separately. Tell us how many globes you are running and we will size a driver for the whole circuit rather than per fitting, which is usually cheaper and always tidier.
Wider. This is a 60° flood, where a halogen MR16 typically threw around 36°. That is better for general lighting and for washing a surface evenly, but if you were using a narrow halogen to pick out artwork or a feature, this will spread more than you expect. Ask us if you need a tighter beam.
It dissipates heat better and it does not yellow. Plastic MR16 globes discolour with age, which shifts the light warm and dims it gradually enough that you do not notice until you replace one. Glass also simply looks right in an open or clear fitting, where a plastic lamp reads as a substitute.
3000 K for living areas, bedrooms and display cabinets — warm and the default in a home. 5000 K for garages, workshops and inspection work, and it is the brighter of the two at 420 lumens against 390. Note there is no 4000 K in this globe, so it is a two-way choice rather than the three most of this catalogue offers.
Yes, with suitable dimmers — but on a low-voltage circuit the driver has to support dimming as well as the dimmer and the lamp. All three have to agree, and buying a dimmable globe on its own achieves nothing. Tell us how you want to control it and we will specify the whole chain.
