Light works great on high, but can not control it. Brightness is definitely a concern for this product, is a bit low for a normal size room. Frustration at it's max.
Installation is very very easy. Very lightweight and easy to install. Lightweight and don't require heavy mounting screws to hold them to the ceiling.
Only problem is that the silver ends tend to droop down a bit and not hug the fixture. The workspace is fantastic.
These lights give off lots of light without the glare of florescent. They are much more bright, come on instantly and even look better when they're off. The quality of the spectrum is fabulous.
The silver-glitter plastic doesn't hug the light, and thus looks warped and as if it's pulling away from the light. These are one shot units. When they burn out, you have to replace the whole unit. Can't replace the bulbs.
