Review on Industrial Dimmable GU10 LED Bulbs: Delivering Equivalent Electrical Performance by Nikki Huang

These bulbs are much brighter than the cheap (Ikea) LED bulbs they have replaced in my kitchen lights. The pleasant warm white (3000K) color of the lamps themselves is spot on and the resulting color rendering of objects in the room is excellent. Using a Lutron dimmer designed for LED and CFL lamps provides a smooth, linear dimming range from zero to full brightness. (Old fashioned dimmers that only work with incandescent bulbs may or may not work). Unlike my old Ikea lightbulbs, they don't flicker or buzz no matter how high the dimming level is. These lamps are great - I would buy more anytime.
