Ott Lights can be found at your Office Depot in their lights. They have various models but most all are the 13 Watt tubes. The light is supposed to give you 'true color'.
But the best value is if you can find the desk models with or without the magnifying lens hood. Michaels crafts store has these in some locations. Watch for their weekly Sunday ads that give you 40% off any item in the store. Then take this and pick up their Ott-Lites of your choice. This is the best price in town until they wise up.
I use one for fly tying and this is the same light offered in the fly tying catalogs for $100+.
Hope this helps the bargin hunters!
