Just like another reviewer, I used this for 2 or 3 years with no problems, then recently I went to use it and it didn't work. Thinking somehow both bulbs had expired, I bought replacements bulbs, and it still didn't work. I took it apart and with a voltmeter determined the electronics inside failed somehow, unfixable by me. I think a work light should last much longer than 2 or 3 years, but that's the trouble with electronics everywhere, the gizmotronics fail long before the lamps or the rest of the product.
