My husband loves this lamp! It's his "go to" for reading everything. From bills, to books, to newspapers, to mail: you name it, he uses it. I'm soooo glad he has this lamp and can now read on his own again. It's PERFECT!

Mom appreciates the lighting, size, and flexibility of this lamp…exactly what she needed for crossword puzzles, reading, and crocheting!

Tungsten halogen lamps should be operated between 95% and 105% of their rated current. Within this operating envelope, the relationships between the operating parameters are approximately exponential. Modifying the current to a value different from the rated current changes the other parameters according to the exponents shown in the table below:

Blue diode lasers are particularly suitable for processing copper, gold and other non-ferrous metals. The high absorption of blue light greatly simplifies the ...

I use the magnifying screen when I make my Christmas stockings. I also just used it for sewing ( I had to rip a black seam out).It was a necessary tool. I love it!

Tungsten filament incandescent lamps, particularly tungsten halogen lamps, are often used in illumination systems. Paired with stable, current-controlled power supplies, they provide extremely stable sources. If the current is altered, the filament temperature changes, with a resulting change in filament resistance. Therefore, the voltage change is not linearly related to the current change. Similar nonlinear relationships hold for other characteristics of the lamp, such as power consumed, luminous flux output, efficacy (lumens/watt), color temperature, and lifetime.

It encompasses radiation with wavelengths ranging from 15 μm (micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz.

This is the perfect height and level of magnification. The light is exactly what I need. I can skip wearing glasses when I use this. It's helped me read not only books but also my phone. So far it's got no negatives- I'll update if anything changes.
