Continuous Lighting without Shadows

Philadelphia and Danvers, Mass. (May 17, 2011) – Lighting designers leveraging fluorescent lamp technology have been challenged by infamous “dark spots” - the unlit space between lamps in continuous cove and similar installations. These dark spots, which affect overall aesthetic, have required luminaire manufacturers to make cumbersome changes, such as staggering lamps to avoid these eyesores. This comes at a cost of enlarging the luminaire cross section, which is unsuitable for narrow coves, slots and niches. To meet the needs of lighting designers and manufacturers, North American lighting leader OSRAM SYLVANIA is pleased to announce the PENTRON® HE and HO SEAMLESS T5 Lamps, offering continuous, smooth lines of light without the dark spots or shadows normally associated with traditional fluorescent lighting solutions.

Aside from eliminating the shadows associated with traditional fluorescent installations, the unique base configuration of OSRAM SYLVANIA’s new PENTRON SEAMLESS T5 lamps eliminates the need to stagger fixtures or lamps in installations. The SEAMLESS T5’s novel base design allows manufacturers to construct more compact luminaires, granting greater flexibility in designing fluorescent lamp installations.

With light output and dimming functionality similar to OSRAM SYLVANIA’s existing PENTRON and PENTRON HO lamps, the HE and HO SEAMLESS T5 lamps may be specified in conjunction with their linear counterparts. These lamps are available in 3000K and 4000K correlated color temperatures and provide excellent color rendering with a color rendering index (CRI) of 85, making them optimal for a variety of indoor installations including retail, hospitality, offices, healthcare and more. The PENTRON HE and HO SEAMLESS lamps are electrically similar to their corresponding linear wattage types and may be operated on QUICKTRONIC® PROStart® T5 and T5HO systems.
