| RT5 Volumetric Recessed Lighting by Lithonia Lighting T5 fluorescent lighting system provides an even distribution of soft, aesthetically pleasing light throughout a workspace, eliminating the glare and hot spots associated with parabolics, according to the manufacturer. It is also said to provide energy savings up to 33% over standard 18-cell, three-lamp T8 parabolics. A two-lamp configuration at 8-ft. x 10-ft. spacing in an office environment can achieve an average illuminance of 53 footcandles, an efficiency of 89.9% at 2,730 lumens per lamp and an input wattage of 58. The depth of 3-1/8 in. results in fewer plenum obstructions, simplifying design and installation. Additionally, a side-access removable ballast tray allows for easier ballast access and maintenance. www.lithonia.com/rt5 |

AddressPro by Universal Lighting Technologies Digital dimming ballasts and controls enable either single or multiple light sources (fluorescent, halogen, incandescent) to function on the same dimming control circuit. The system also allows users to independently control multiple lighting zones and is available for compact fluorescent, T5, T8 and T5HO lamps. It can control as many as 250 ballasts, which can be separated into as many as 12 zones with 12 unique scenes, and provides dimming levels down to 1% for T5 and T5HO lamps and 3% for compact fluorescent and T8 lamps. Control options include wall stations, handheld remotes, ceiling module controls and wall-mounted rotary switches. www.universalballast.com |
| Demand Response for Simplicity Series Dimming Systems by Hunt Dimming Demand response capability for the manufacturer’s dimming systems offers a variable load-shedding strategy for interior building lighting. The feature addresses the need of large energy users to avoid peak-time-of-day rates, allowing them to participate in utility-sponsored rate-reduction programs offered in exchange for load-shedding practices that lower electricity costs and conserve energy. Proprietary software incorporated into the digital dimming panels allows for system designs where load-shedding control is directly administered by the utility, maintained on-site by the facility owner, remotely initiated by a centralized office with local override options or integrated into an ancillary building automation system, in order to provide the desired load shedding for lighting while being incorporated with additional load-shedding strategies for other building systems. www.huntdimming.com |
