The Softech DL-90 Multi-Function LED Desk Lamp
This lamp was just released this year by Softech, and it has a lot going for it. The lamp incorporates 27 high-power daylight LEDs. The Color Rendering Index of the LEDs is rated at 90+ (excellent).
The lamp has four distinct lighting modes and 40 brightness levels in total. The first two modes are for desk work: a reading mode with mid-range colors (4300K-5300K) that are easy on the eyes, and a study mode which has a high range color temperature (6000K-7000K). The lamp can also be switched to a relaxation mode and a sleep mode — these have softer, warm color temperatures.
This lamp uses 10 watts or less of power to provide light equivalent to a 100 watt incandescent bulb. It is said to last about 40,000 hours or 20 years of normal use.
A handy feature of this lamp is the “auto off timer”. The timer will turn the lamp off after one hour, saving your power if you forget to turn it off. It has a USB charging port.
The Softech DL-90 lamp is available from Amazon for about $90.
