I just got a job needing solar LED lighting, and I searched everywhere... the caveat is that it couldn't be mounted on the ground...
I came across this,
www.earthtechproducts.com/solar-wall-washer-light-400-lumens.html
And I just got it in. It seems well built, and I can't wait to try it. I did have to build a mount, so I used rectangular tube, and will have it powder coated...
