Humanscale DT2E Double Arm with Shade Diffrient Task Light




Sustainability and sleek aesthetics reach new heights with the elegantly engineered Diffrient Task Light II

An effortlessly adjustable task light that supports the latest ballast-in-bulb technology, the Diffrient Task Light II maximizes the efficiency of compact fluorescent bulbs to provide long-lasting pure white illumination while maintaining the slim design aesthetic made popular by the original Diffrient Task Light. The improved design eliminates the in-line ballast brick to minimize component failure rates and eradicate leakage currents.


Boasting sleek good looks and the longest reach on the market, the Diffrient Light is precision-designed and engineered with a perfect internal counterbalance. One-touch positioning—without the friction knobs or rigid joints found on other task lights - enables users to easily move and angle the light exactly where they need it most.


Available with a single or double arm, the Diffrient Task Light II is made primarily of recycled aluminum and features a slim, parabolic shade to improve illumination and prevent glare.

Diffrient Light and the Environment:

The Right Material: All Humanscale task lights are constructed primarily of 100% recycled aluminum. In addition to a high scrap value that increases the likelihood of recycling, the energy required to recycle aluminum is just 5% of that used to produce virgin aluminum.


The Right Bulb: Not only do compact fluorescent bulbs (CFLs) save money, they save energy too. Using just 25% of the energy of comparable incandescent bulbs,

CFLs give off 75% less heat, and last up to ten times longer. They’re also 50 to 100% more energy efficient than LEDs.


Earn LEED Credits: The Diffrient Light contains 77% LEED recycled content, and can help a project achieve LEED credits in a number of categories:

  • ID Credit 1.1 – 1.4, Innovation in Design: Ergonomics Strategy

  • MR Credit 4.1, Recycled Content, 10%

  • MR Credit 4.2, Recycled Content, 20%

  • EA Credit 1.1, Optimize Energy Performance, Lighting Power

  • EQ Credit 6.1, Controllability of Systems, Lighting




Benefits of Energy Efficient Task Lighting:

Improve Comfort: Different tasks and different users can require significantly different levels of light, and therefore can’t be accommodated by single-source overhead lighting schemes.


Task lighting, then, is essential for ergonomic comfort by supplying the right amount of adjustable illumination for each user and task while reducing eyestrain, headaches, monitor glare, and other symptoms caused by poor office lighting.


Energy Efficient Task Lighting improves comfort



Save Energy: When task lights are implemented at each workstation in an office, ambient lighting levels can be reduced. And when lower levels of overhead lighting are combined with energy-efficient task lights, the cost-savings can be significant.


What’s more, lights designed for use with compact fluorescent bulbs (CFLs) offer superior energy efficiency compared to those utilizing incandescent bulbs or LEDs.
