The Dorfam Series stands out as our most flexible office lighting solution. Unlike standard series that are only recessed, Dorfam offers both Recessed (OF4x) and Surface-Mounted (OF5x) versions, allowing you to maintain a consistent design language across buildings with mixed ceiling types (concrete and grid).
One of the unique features of the Dorfam series is the inclusion of ultra-high-power models (OF48 & OF58). With 90 Watts and 9500 Lumens, these fixtures act as “Office High Bays,” capable of illuminating spaces with ceiling heights exceeding 4 meters, such as large lobbies, atrium entrances, and conference halls.
Question: What is the difference between Recessed and Surface Dorfam models?
Answer: Recessed models (codes starting with OF4) are designed to drop into T-Bar ceiling grids. Surface models (codes starting with OF5) have a specialized housing that allows them to be screwed directly onto solid ceilings like concrete or drywall without needing a cut-out.
Question: Why would I need a 90W panel (OF48/OF58)?
Answer: Standard 40-50W panels are designed for normal ceiling heights (2.8m). If your office or showroom has a high ceiling (4m+), standard panels won’t provide enough light on the floor. The 90W Dorfam model delivers 9500 lumens, ensuring bright illumination even from a distance.
Question: Which 50W model should I choose, OF44 or OF41?
Answer: While both are 50W, the OF41 is a “High Efficiency” model producing 6000 lumens (120 lm/W), whereas the OF44 produces 5200 lumens. If energy saving and maximum brightness are your top priorities, the OF41 is the superior choice.
