The new Daylight Omega 7 Pro Magnifier is a modern, ergonomically designed magnifying lamp. It has a large 17.5cm (7”) diameter, 3 diopter (1.75X), lightweight acrylic lens and high power LEDs with 4 brightness levels for clear viewing. The internal spring arm allows accurate positioning. An optional 12.7cm (5”) diameter, 5 diopter (2.25X) lens and a 12 diopter (4.0X) swing arm lens are available separately. In our opinion this is quite simply the best Magnifier lamp lamp on the market today. It is ideal for hobby or professional use.
