Halogen MR16 spotlight for low-voltage fixtures
This 150 W, 21 V tungsten-halogen capsule produces 170 lumens at a 3400 K colour temperature with a CRI of 100. It fits GX5.3 bases and is intended for accent or task lighting where precise colour rendering matters.
Sustained output and short rated life
The filament runs at full power continuously, delivering stable light without warm-up delay, yet the rated lifetime is only 40 hours. Frequent replacement should be expected in installations that operate for long periods each day.
Compact reflector capsule with pin base
The MR16 reflector envelope directs light forward in a defined beam, while the two-pin GX5.3 connector plugs directly into compatible low-voltage sockets. No external ballast or driver is required beyond the 21 V supply.

Questions about this item
Does the 150 W halogen draw enough power to create noticeable heat during extended use?
The lamp runs at 150 W and 21 V, so it produces significant heat; ensure the fixture is rated for that wattage and keep flammable materials clear.
What transformer or driver must I already have for the GX5.3 base to operate?
You need a compatible 21 V low-voltage transformer or electronic driver that supplies the correct voltage for the GX5.3 base.
Can I keep my existing MR16 fixtures and dimmers when switching to this 3400 K lamp?
The MR16 form factor fits standard GX5.3 sockets, but verify your dimmer supports halogen loads and the 3400 K colour matches surrounding lights.
