Ultra-Efficient 90 LED Magnifier Lamp - Adjustable Arm - 5" Lens
Ultra-Efficient 90 LED Magnifier Lamp - Adjustable Arm - 5" Lens Reviews
The description of this item has changed a few times, and some of the reviews appear to be for different lamps. I ordered and received a 90 LED lamp from ProMagnify and it's better than I expected at this price. The lens is indeed glass and the optical distortion at the correct working distance (about 5-8 inches) is minimal even towards the edges. If you try to view something from too far away, then there's more distortion, but that's normal. The box indicates this lamp comes in both a 3 diopter (1.75X) and 5 diopter (2.25X) version. Mine is the 5 diopter. The 3 diopter version would let you view things from farther away (10-13 inches) while a 5 diopter lamp is best for really fine work with small objects. The 90 LEDs are not as bright as similar fluorescent lamps but they're plenty bright for close viewing at the correct distance. And unlike flourescent lamps, they run cool, there's no flicker, buzzing, etc. If you intend to use this as a general desk lamp with it high above your desk, however, don't expect 60 watts worth of incandescent light like you'd get from even a 13 watt flourescent. I'd say it's closer to half that. The color of the light is "cool" but not overly blue like some LED lights can be. It's similar to a 3500K - 4000K flourescent (i.e. "cool white"). Working with the magnifier it's about the perfect amount of light and uniform with no shadows. There's a power supply for the LEDs built into the "ring" around the lens near the on/off switch and that area runs a bit warm after its been on a while but far from being hot. The LED's, however, will likely far outlast the switching power supply. My only real complaints are the lens is a bit loose and moves around (but it's in no danger of falling out), you have to really tighten the clamp at the head to keep it from "drooping" down under its own weight, and I'm a bit concerned the "ball socket" at the head that lets you pivot the lamp/lens might loosen up someday and not hold its setting. But those are, so far, minor complaints. It's mostly well designed and made. Overall, it works well. And considering it costs *less* than a lot of fluorescent magnifier lamps of this size with decent lenses, it's a relative bargain.. this is my Ultra-Efficient 90 LED Magnifier Lamp - Adjustable Arm - 5" Lens reviews
Ultra-Efficient 90 LED Magnifier Lamp - Adjustable Arm - 5" Lens Specs
- As we age, our eyes naturally lose some of their ability to focus close-in. A teenager can focus on objects as close as 3" but by age 50 that distance can increase to 18" - VERY frustrating when it limits your work or hobby. This premium-grade lamp is a simple and effective solution for seeing almost anything bigger, better and brighter. 36" triple-joint arm has unique internal cantilever system that lets you adjust without loosening/tightening knobs - perfectly balanced to hold position (can be locked in position if necessary). Heavy-duty die-cast aluminum clamp with no-mark pad, nickel-plated steel screw fits surfaces to 2-1/2"-thick; easy to move remove and takes up just 2" of desk space. Large 5"-diameter glass lens with 5-diopter (2.25X) magnification lets you see fine detail clearly but still has a practical focal range (distance of text or object from lens) of up to 9". 90 individual super-bright LED illuminate with pure white light without the heat build-up of incandescent or halogen and without the flicker of fluorescent. Consumes less than 6-watts power with estimated life of 100,000 hours. Conveniently placed power switch on lamp head, flip-up dust cover protects lens & keeps it clean. Overall length 48", weight 7 lbs 72" 18AWG UL-listed power cord.
