    Rated 3 out of 5 by from Futuristic look Fixture has clean modern look. We retrofitted a few samples into an office that was being renovated. No one liked the glaring light in their face as compared to the old parabolics that they were used to. I even used the 3500K for a softer look. I really like the design and install qualities of this fixture, but the light should be available with some kind of a lens accessory that would direct the light down onto the desktops instead of a wide glaring pattern in the room.

    1. Is there a 2 x 2 similar fixture? 2. Which is better --- 4000K or 3500K for color rendition in a traditional office setting? 3. How many watts do these fixtures consume when on?

    Asked by: PH123
    This is a 39w fixture. 4000k is traditionally better for office settings but it really is a personal preference. The 2x2 fixture of these is located here: http://www.e-conolight.com/e-tbb03a-22r35n.html - 3500k http://www.e-conolight.com/e-tbb03a-22r40n.html - 4000k

    Can these be dimmed, and if so do you sell the dimmer or is it a standard dimmer?

    Asked by: Ron E
    These fixtures are dimmable. The driver on this fixture is dimmable. While we do not sell a dimmer at this time, most Lutron dimmers with 0-10V dimming capability will work with the E-TBB Series.
