This Feit 500-lumen replacement bulb is the same bulb that’s supplied with the 500 Lumen Moffatt LED swivel base work lamp. The built-in 40-degree enhanced reflector provides broad, even coverage without hot spots common to other brands of work lamps. True to life, this bulb helps you see the natural color of the wood as it really is while being easy on your eyes. MR16 style base.
