These things work perfect. Works as advertised. Work like a champ!

Nice & bright w/o harsh glare. Only thing i don't like 100% is the bulb itself is white color instead of transparent. Makes it cute with the design and ease.

The 4000k i ordered, lean much closer to 5000 k branded (philips) bulbs. Incandescent last a lot longer. However, the color temperature is way off in my opinion and by my rudimentary measurements.
