Very pleased with the purchase of these two Daylight Mag Lamps. The price reduction was greatly appreciated as I purchased (2) Lamps as a very small business owner. My field of vision is significantly larger using the 3 Diopter lens and has made the performance of my job much easier. However, the purchase of the additional (2) 5 Diopter lens ($46 each) was disappointing as my field of vision was reduced greatly making my job less effective. Over all I am very satisfied with my purchased!
