Your eyes have a remarkable ability to adapt to low light, to a point where your shop might not feel dark but it actually is. At least for woodworking purposes… I had two LED bulbs illuminating my space and they just weren’t enough. Chopping mortises was particularly difficult as I’d just revert to blindly stabbing the mortise floor hoping errant pieces of wood were lurking in the shadows. Enough. Enter hyperikon led lights. Simple to install and enough lumens to give me a nice tan.
