Description
The LightView PRO Colors Edition Magnifier Table Lamp comes strongly recommended for anyone facing challenges due to macular degeneration. The 3-diopter magnifying lens brings an entire page into focus - there's no need to move a book or newspaper around as you read. Ideal for use as a craft lamp, LightView PRO lets aging eyes see intricate embroidery close-up once more!
Best of all, it's dimmable and it's adjustable for direction as well as color intensity. The flexible neck pivots to reach up, down, and side-to-side at angles that best suit your height comfort, as a bi-touch dimmer lets you select your desired lighting level. The most innovative feature, however, may well be a color adjuster on the lamp head. If the full brightness of cool white color feels too harsh on your eyes, LightView PRO Colors Edition gives you a choice that lesser lamps don't provide. Now, you can have it both ways. When you need daylight bright lighting to see every detail, opt for the color temperature of 6,000 Kelvin. For those times when you prefer softer lighting, select the more soothing warm white of 3,000 Kelvin. You can also adjust the color level anywhere in-between 3,000K - 6,00K. Dimmability feature also allows you to adjust the brightness level.
We make our Magnifier lens of genuine diopter glass; cheaper units only paste plastic magnifying sheets onto ordinary glass. Brightech's high-quality 3-inch diameter lens magnifies 2.25 times - eliminating eyestrain for elderly readers. There are less expensive magnifier lamps out there, but none of them has the quality or workmanship of a Brightech lamp. None of them has the vivid daylight hues of power-bill-saving LED. The 90 LED lights embedded here use only 9 watts altogether - a model of efficiency!
