Highly energy-efficient, LED lighting consumes only 1/8th of the power of an incandescent lamp and less than half of the power of a fluorescent lamp. LED lighting also renders color accurately, reduces eye fatigue, and stays cool. This new design desk lamp is based on our standard High Illumination Light Fixture no. 300-381, and provides even more illumination. This lamp is also dimmable, unlike most task lighting fixtures. Its modern design looks good on your desk or in your workshop. All aluminum construction resists corrosion. The 24 1/2" shade has an integral light-diffusing shield that spreads light evenly to reduce eyestrain. Fully articulating and easily adjustable arm has a 33" reach. Can be attached to your work surface with 4 wood screws or you can use the C-style clamp (provided) for bench tops up to 1 3/4" thick. Dual voltage (110V/220V). Furnished with 110 volt plug. Made in Taiwan.
