Homie LED down-lights are available in a MR16, which is the standard replacement bulb for 12V down-lighters; and the GU10, which is made for use on 220V currents. Generally, modern houses use the 220V instead of plugging the 12V into a transformer in the ceiling (as many older houses do). The only difference between the two is the connection.
Most customers order the warm white color option which is perfect for indoor home lighting and mood or decorative lighting. Cool white is refreshing and vibrant for patios or offices. This light bulb is very durable, with a stainless steel light reflector, making it weather resistant, and LED lights (1 per Watt) for a life that lasts up to 50 000 hours!
This range of down-lights is split into dimmable and non-dimmable products. If you already have a dimming system in your house/room, you may need to make sure that the LED light is suited to your system to ensure no disappointment.
