The LFM LED is Luxo's most cost-effective LED magnifying clamp on style lamp. With a 5" diameter, 5D (2.25X) lens and a 7W dimmable LED, it offers a great choice in illuminated magnification. The flexible, spring-balanced 45'" long arm ensures the magnifier can be placed in any position.

I am very pleased with the quality of this lamp for office work at my computer desk; additionally, I have benefitted from the magnifying glass several times. The adjustment mechanism is performs well and seems sturdy. A month or so after purchasing the initial lamp, I bought another for a different work area.
