Mesopic Technologies specializes in the manufacturing and distribution of the latest technologies arising from the rapidly expanding light emitting diode (LED) market.

Advacements in lighting design and the inherent Mesopic output of LED’s create several reasons to choose this technology over conventional incandescent, induction or HID fixtures.

• Uses 60% to 90% less energy than conventional lighting.
• Extreme longevity… 50-75,000 hours at >80% efficiency compared to a metal halide lamplife of 15,000 hours at 60%.
• Meets RoHS no mercury or other hazerdous materials
• Mesopic Multichip™ generates 120 lumens per watt
• Instant firing even in extreme cold
• No maintenance
• Durable waterproof design
• Assembled, tested, and certified in Canada

What is Mesopic and how is it possible for a 50W floodlight to replace a 250W sodium fixture? The answer is in the definition of Mesopic vision and visual effective lumens (what your eyes see and respond to).

Scotopic vision is the scientific term for human visual perception in low light (night) detected by rod cells in your eyes.

Photopic vision is the scientific term for visual perception under normal daylight conditions detected by cone cells in your eyes.

Mesopic vision is the function of the eye that is used in the intermediate level of illumination where both the rod and cone photo receptors are acting in processing light input simultaneously.
