Can I use these dimmable LED bulbs with my old existing dimmer switch at home?
Dimmers originally designed for halogen or incandescent bulbs typically require a minimum load of 40–60W; a single low-wattage LED bulb often fails to meet this threshold, which may result in flickering, humming or unstable brightness.
What base types do you supply, will they fit standard UK lamp holders?
We offer dimmable bulbs with a variety of base types, such as GU10, B22, E27 and E14. For further details, please visit the GY flagship store.
Compared to standard dimmable LED bulbs, how much energy do Grade B dimmable bulbs save?
The GY GU10 LED bulb is rated at energy efficiency class B, which is far superior to conventional E/F-rated energy-saving bulbs, and can reduce lighting costs by up to 93.8%.
What is the lifespan of this bulb? I don’t want to have to replace it too often.
Rated lifespan: Up to 30000 hours (far longer than halogen’s ~1,000 hours), minimal heat output so less wear on lamp shades and fittings
