LED MR11 (G4 backpin) 9xSMD inserts in Cool White
Replaces this glass MR11/G4 backpin bulb in vertical fittings and applications.
Designed to fit into small openings, this G4 backpin/MR11 insert has a very low heat footprint due to its lack of a reflector cup.
For LED bulbs the reflector cup isn't required and tends to seal in the heat once we get into the larger quantity of LED.
We do stock a reflector version in the 9XSMD if you need the bulb to be a conventional size....

What is the difference between Warm White and Cool White?
Warm White has a pleasant incandescent tone to the light whereas Cool White is a plain paper White.
The human eye naturally doesn't see Warm White quite as bright as Cool White.
In real terms of Warm White bulb has about 90% of the lumens efficiency of a Cool White unit.
The bad news ends there for Warm White bulbs.
Over the years we've seen a slow transition towards Warm White mainly due to the fact that Cool White got itself a black eye from the early LEDs going blue tinged.
In short - ladies far prefer Warm White to Cool White.
The men prefer Cool White as it is a slightly brighter work light.
