Energy Efficient Technology – The Hidden Benefits That Are Right Before Your Eyes
By David Leighton

For decades now, concerns regarding energy efficiency have been a part of a conversation that reaches from the individual through business and local government, all the way to international levels. When it comes to energy efficient technology in the industrial and broadcast video industry, most manufacturers have primarily been focused on portable devices toward the singular goal of extending battery life. Rarely do you hear mention of efficiency in AC powered video headend equipment or that energy efficiency was even considered during the various stages of product design. As a result, many video headend components operate day in and day out with little or no regard for energy consumption, the associated thermal load placed on environmental systems, or the stresses heat places on electronic components in general. Today’s ever increasing energy costs coupled with power hungry technology brings focus to a figure that was typically buried in a profit and loss statement. The energy efficiency of a product and its associated cost savings has reached an amount today that could represent a significant impact on the financial health of a business.

LEIGHTRONIX is proud to introduce a new generation of products in which energy efficiency was built in from product inception, through design, and into manufacturing. Our new UltraNEXUS-HD™, UltraNEXUS-HD Blade™, and IncodeX Blade™ products are the first in a line of high-performance headend video devices that require just a fraction of the energy of legacy systems and most present day offerings.

As an example, our new UltraNEXUS-HD Blade system packs 12 high-definition video servers, with independent graphics per channel, into a compact four rack unit chassis, and draws an astonishing 220 watts of AC power total, even when configured with redundant power supplies. Contemporary server systems with similar specifications draw upwards of 50 to 75 watts of AC power per channel, and therefore would draw 600-900 watts in order to provide the 12 channels of the UltraNEXUS-HD Blade system. With the UltraNEXUS-HD Blade, however, a station or other type of channel provider can operate on less than 25 percent of the AC power when compared to other systems, with less dissipated heat, and in a significantly smaller amount of physical space.

As mentioned earlier, significant energy savings translates directly into cost savings. The table below compares a 12 channel operation using the UltraNEXUS-HD Blade to an operation using other standard servers on the market. Instead of composing a blog post with more written descriptions and comparisons, I’m simply going to let the numbers do all the talking. I think you’ll find they say a lot.


The hidden dollars associated with the energy efficiency of any product rarely show up on a price list, but they are both valuable and recurring. We’re excited about what this new line of energy efficient technology will mean for our customers and the impact it will have on the broadcast industry as a whole.
