New generation office lighting combines state-of-the-art ActiveLED, electronic and mechanical design, CCT Color Temperature choices 2700K, 3000K, 3500K, 4000K and 5000K

The ActiveLED^® OL4 Series Troffer / Recessed Panel Light consumes at least 50-85 percent less energy than conventional lighting and additional energy savings can be achieved with optional light management.

With its patented design and superior LED elements, the ActiveLED OL4 Light is a reliable light source with a 90,000-hour lumen life, making it a maintenance-free solution for applications where changing bulbs and ballasts can be costly and hazardous.

Significant savings from not having to maintain and renew ballasts and fluorescent tubes in light fixtures, reduced heat generation and energy use justify the initial outlay.

ActiveLED^® Technology

Ringdale uses the latest in energy efficient LEDs and LED Modules producing equal or greater light output than fluorescent light fixtures. Our state-of-the-art electronics monitor current and temperature of the substrate to assure maximum performance under the prevailing environmental conditions and a Lumen Lifetime of 90,000 hours (90% Luminous Flux).

ActiveLED^® Diffuser Technology

We use state-of-the-art diffuser technology with a minimal amount of light loss in the fixture providing for maximum lighting efficiency.

ActiveLED^® Architectural Features

Ringdale ActiveLED^® Recessed Panel / Troffer fixtures act as a heat transfer barrier between office (air conditioned) space and ceiling (non-air conditioned) space.
Ringdale Panel Lights are half the height of a conventional fluorescent light fixture and half the weight putting less stress on the straps and strips holding the ceiling.

Optionally, any ActiveLED OL4 troffer can be configured as an Emergency Battery Back-Up fixture with the inclusion of an integrated battery and push-to-test (PTT) button.

ActiveLED^® Warranties

We provide mechanically robust indoor lighting systems; our warranties are 10 years on LED elements, fixtures and drivers / power supplies.

Ringdale is an ISO 9001:2000 company, registered under BSI certificate FM-1880. Ringdale provides products of the highest quality designed and manufactured in Texas, USA and in the United Kingdom.
