I've been thinking about buying a SL20X for a long time and going with a SL35 lamp to get more light out of it. I decided that I might not use the light much since I'll primarily will be using a Stinger so I decided to go with something cheaper for a bright light for those occasions when I need it. I bought a Home Depot Husky 1 million candlepower aluminum spotlight, made by Vector. I thought I'd be happy with it but I don't care for it. The beam quality is poor and having to click through light settings each time to get to the brightest one is a pain. It also doesn't have as much throw as I wanted. Also on bright the light only has about a 15 minute runtime I've also got a 2.25 million cp Home Depot light and it gives me all the light I need and a good beam but it too big and awkward for my intended use now. After my bad experience with the vector I'm reconsidering the SL20X / 35. The question I have is how does the throw / beam quality of the SL35X compare to Vector that I bought (Husky 331-623)? I need something I can use one handed while driving if need be so I think some of the larger spotlights are out of the question. Also the opening for the sliding side window on the motorhome I'll be traveling in for a few months is too small for a large spotlight to fit out of it easily. John
