How Will It Help?

Key Features

Gemini Table Light

  • Adjustable Beam Pattern

    This revolutionary new light allows you to change the beam pattern to suit your needs. The adjustable LED beam-width and intensity technology means you can switch beam patterns at will according to the area you need to light up.

    Adjust the beam-width between a very bright, narrow, concentrated spot and a wider, less intense flood beam. Precise, variable high quality beam control means you can concentrate for longer and read in more comfort.

  • Daylight Wavelength TechnologyTM

    There is nothing quite like daylight - we've all experienced the urge to move closer to the window to see better. Serious Lights replicate aspects of natural daylight for which our tired eyes yearn.

    Since inventing our first light over 35 year ago, Serious Founder Alex Pratt OBE has been leading pioneering research into shedding natural light indoors to radically improve our sight.

  • Up to 8x more light on your page

    Unlike multi-directional lamps, the Serious design focuses all of its colour corrected light on your page, making it many times brighter than traditional lights.

    By comparison with a traditional 60W filament bulb, the Varifocus Light throws between 4-8x more light onto your page depending on the spread of light you choose.

    This helps to correct the typical loss of light reaching the retina of two thirds by the time we reach 60 years old.

Why Choose Serious?

A focused beam for reading and a broader beam when required. Fantastic.

Option 1

Base Type

Heavyweight Models

  • Weight13lbs (5.7kg)
  • Height29" (75cm)
  • Base Diameter9.5" (24cm)

The deliberately heavyweight base ensures your light is planted firmly on the table or desk. Built to robust industrial standards. It plants itself firmly for single-hand operation.

Option 2


  • Black

    The brass base metal is double sprayed and double-baked to produce a durable matte black coating for the fully flexible stay-put arm.

  • Nickel

    A 15-20 micron brushed nickel coating on the brass base metal gives a sharp hi-tech brushed finish.

  • Brass

    The 20-30 micron of zapon-treated brass on brass provides a long-lasting classic look when paired with the real wood mahogany effect handle.
