OL4 Series of LED Recessed Ceiling Lights for 2' x 4' and 600mm x 1200mm Ceiling Grids, choice of wattages, 3500K and 5500K

Developers, Architects and Municipalities are faced with ever increasing energy cost. Ringdale LED Indoor Panel lighting systems offer an opportunity to convert to environmentally safe LED Indoor Panel Lighting.

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.

Warranties

We provide mechanically robust indoor lighting systems; our warranties are 10 years on LED elements, 5 years on other materials and workmanship and 3½ years on batteries and super-capacitors.

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.

LED Technology

Ringdale uses the latest in energy efficient LEDs and LED Modules producing equal or greater light output than state-of-the-art fluorescent light emitters. Our electronics monitor current and temperature of the substrate to assure maximum performance under the prevailing environmental conditions.

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.

Architectural Features

Ringdale light 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.
