Stable and sharp magnifying lamp with lots of light

After various experiences with magnifiers lamps of "mouth" and "Tool Craft" I am now at the manufacturer "Lumeno" landed. The "mouth" lamps were bulky adjustable, due to its dual energy saving lighting (2x9 Watt) had to wait until halfway had light and heat has been given or made. Positives: The magnifying glass itself was of high quality. The "Tool Craft" lamp was with her 22-watt ESL appreciably more light, unfortunately, the lens was not as sharp mapping and adjustment was a disaster: All arms were heavy adjustable while remained the heavy lamp head but not where one wanted him. The ballast at the bottom warmed considerably.

I chose the model with 8 diopters, the last digit in the model name indicates the diopter number. From five centimeters are under the magnifying lamp:
3 diopters = 1.75 = 8.75 cm fold magnification
5 diopters = 2.25 x magnification = 11.25 cm
8 diopters = 2.75 x magnification = 13.75 cm

The "Lumeno 7218GR" does everything right: The arms are fully enclosed and are equipped with very strong springs. This allows the light bulb head adjust kompfortabel, actually extends the little finger. Here, the lamp head stays exactly where you positioned it. The magnifying glass itself is at least as sharp as mapping the "mouth" -Lupenleuchte. The 80 LED provide without delay a legal kaltes-, daylight corresponding light, I guess 4000 Kelvin color temperature:
Distance 50 cm = illuminance 80 lux
Distance 25 cm = 225 lux illuminance
Distance 10 cm = 670 lux illuminance

Conclusion: High-quality and steadfast light with sharp motion and plenty Lichtleistung- full five stars!
