I have two sets of the dual halogen work lights and a couple of florescent and incandescent work lights. The problem is being able to move around under the lift with the lights. I wind up either knocking them over or having them shinning in my eyes or the light being concentrated in the wrong direction. These daisy chained lights just seem to be right for the four post lifts. They attach with magnets so I could string them up on the decks and the light can be directed exactly where I want without being in the way or shinning in my eyes. Pricey yes, but I find most things worth having do cost a little more. I think my wife’s giving them to me for father’s day. After I get them I’ll let everyone know how they work out.
