Questions about this item

How bright is the 300 W output in a real fixture?

The 300 W rating delivers a 3400 K colour temperature with a CRI of 100, giving a white, colour-accurate beam suited to projectors, medical and stage lighting.

What does the GX 5.3 base cap in practice?

The GX 5.3 two-pin base limits use to fixtures designed for that pin spacing and the 82 V supply; it cannot be used in standard mains-voltage sockets.

How much space does the MR13 reflector need to mount?

The MR13 multifaceted reflector has a 13 mm diameter, so the fixture must accommodate that narrow profile and the GX 5.3 base depth.
