MR16 LED bulbs that drop straight into your existing 12V and line-voltage fixtures, sold by the case for contractors and facility teams. Votatec stocks GU5.3 bi-pin and 120V MR16 LED bulbs in warm and daylight colour temperatures, dimmable and CCT-adjustable options, for track heads, accent lighting, retail display and low-voltage outdoor systems.
Types of MR16 Bulbs We Carry
Most MR16 LED bulbs run on 12V through a transformer, the same as the halogen lamps they replace. We also stock 120V line-voltage MR16 LED bulbs for fixtures wired direct, so you can match either system. Every bulb uses the standard GU5.3 bi-pin base.
12V GU5.3 MR16 LED
The standard low-voltage spotlight. Drops into existing 12V track, recessed and accent fixtures. Best paired with an LED-rated electronic transformer.
Dimmable MR16 LED
Smooth dimming for retail, hospitality and display work. Match the bulb to a compatible LED dimmer and transformer to avoid flicker.
3-Way CCT Adjustable MR16
One bulb, three colour temperatures (warm to daylight) set at the bulb. Cuts the number of SKUs you carry across a mixed project.
Warm vs Daylight White
2700K-3000K for warm accent and residential-feel spaces, 4000K-5000K for retail and task areas. We supply both across the range.
MR16 LED for Track, Accent and 12V Outdoor Systems
MR16 LED bulbs stay popular for one reason: a tight, controlled beam. That makes them the go-to for track heads, recessed accent cans, retail display and low-voltage outdoor landscape lighting. Beam angle matters here. A narrow 24-degree spot picks out signage or product; a 36-40 degree flood washes a wider area. Tell us the application and we'll match the beam spread, colour temperature and lumen output to the fixture.
Replacing Halogen MR16 with LED
Yes, you can swap a halogen MR16 for an LED MR16 in the same fixture. Same GU5.3 base, same form factor. A 5W to 7W LED replaces a 50W halogen and gives you roughly the same light for about 90% less power.2 One catch on 12V systems: older magnetic transformers don't always drive low-wattage LED loads cleanly, which shows up as flicker or bulbs that won't start. If that happens, switch to an LED-rated electronic transformer. Line-voltage 120V MR16 LED bulbs skip the transformer question entirely.
GU5.3 Bi-Pin vs GU10: Choosing the Right Base
The difference comes down to two pins versus a twist-lock, and the voltage behind them. MR16 LED bulbs use a GU5.3 bi-pin base and usually run at 12V. GU10 bulbs use a twist-lock base at 120V line voltage, no transformer needed. Check the socket before you order: two thin pins means MR16, a twist-and-lock means GU10. If you're comparing reflector sizes, our PAR LED bulbs cover the larger fittings.

MR16 LED vs Halogen: The Numbers
| Factor | MR16 LED (5-7W) | MR16 Halogen (50W) |
|---|---|---|
| Power draw | 5-7W | 50W |
| Energy savings | ~90%2 | baseline |
| Rated life | 25,000-30,000 hrs2 | ~3,000 hrs |
| Heat output | Runs cool | Runs hot |
| Canada status | Meets efficiency rules | Halogen MR16 restricted under federal regulations from 2025-20261 |
The regulation point is the one to plan around. Natural Resources Canada brought MR16-style reflector lamps into its general service lamp efficiency rules, with new requirements effective 2025-10-09 and manufacture limits from 2026-01-01.1 Inefficient halogen MR16 lamps are on the way out. LED MR16 already clears the bar, so retrofitting now avoids a scramble later.
