Frequently Asked Questions
How bright is it?
The listing states 400 lumens.
Is it dimmable?
Yes, the listing says it is dimmable. Check your dimmer.
What fixtures does it fit?
It is a GU10 reflector bulb with an GU10 base. Check that the base and size match your fixture, and the fixture’s maximum wattage.
Can I use it outdoors?
The listing does not mention wet, damp, or outdoor use in the text we saw. Do not use it outdoors unless the maker says it is allowed.
Note: switch the power off and let a bulb cool before you change it. Stay within the fixture’s maximum wattage, using the bulb’s actual LED wattage and not the “equivalent” figure. Reflector bulbs sit in recessed cans and track heads where heat can build up, so check the fixture label, and check whether a bulb is dimmable and whether it is rated for enclosed, damp, or wet locations before you use it there. Low voltage MR16 bulbs need a matching transformer or driver. Look for a UL or ETL mark, and follow the maker’s instructions. Listings differ; we describe what each maker lists.
