I like the OTT lite for convenience and portability but it's not the brightest light out there. It folds up and fits in my travel bag though, and is plenty of light to make a hotel table work wonders. Natural color lighting looks more like daylight so they say, seems to hold true. I got it cheap at Costco.
At home I either use my halogen high intensity lamp and the naked eye or an incandescent manifier lens lamp (under $25 at any big office store nowadays) for trout flies and mixed wing salmon flies,etc.
My favorite place to tie is on the tailgate of my truck at Chatham light parking lot.
