4.0 Quick, easy and bright. Good not great. A step backward. Pricey.

If you have keyless fixtures and want a very quick and easy way to increase light output these are hard to beat. The light source is essentially a point, so combined with the brightness you will get significant shadowing. You can get better results for less with 4' shop lights if quick and easy aren't a priority. Hopefully competition will drive down the price. Margins have to be strong. The new design is a step backward in my opinion, particularly the smaller shroud, likely a cost cutting change - less material & smaller box = more per pallet from China. Old box was a pyramid which worked well. New rectangular box is just barely big enough to fit the reflector, so protection seems marginal. One of mine came with a dented shroud and scratches on the white plastic cover. It was actually packaged in a larger box with more protection, so I'm betting it was shipped from Keystone damaged (maybe a return?). Not worth the trouble to exchange. I have both old & new design in my garage. New design is more reddish tint. Original more yellow. Original reflector has slightly better horizontal coverage, shines a little higher on the wall if that's a concern. They are very bright. I hope this review helps someone.
