Got it Friday. Mine DOES NOT have mode memory as stated on at least one online retailer's product page. "Intelligent memory circuit. Automatically enters the previously used brightness level when turned on." I researched the thing on one site, but bought it on another because the grey was in stock. Should have waited for a review. I will not be able to use it as I intended. Nothing in the manual states that it is supposed to have memory. My mistake. Haven't used it enough to comment further...
