Techniquip's Proline 40 LED Ringlight is a durable, reliable, and powerful ringlight for industrial microscopy. The Proline 40 high utilizes 40 high quality LEDs which are precision aligned to provide an even, shadow-free and bright illumination cone over the full working distance range.

Features

• High intensity operation over full lifetime,
• Precision aligned, heatsink mounted LEDs for uniform illumination over target area

• Daylight color output,
• Precision machined and hard anodized aluminum alloy LED ring fits up to 66mm objective lenses,
• Remote on/off, segment and dimming controls,
  
• Made in the USA.

Specifications

• Rated lifetime of over 50000 hours,
• Constant current LED driver to minimize intensity decline over the life of product,
• Dimming of 15% to 100% without color shift effects,
• Enable buttons for 4 segments (Each is 90 degrees section, 10 LEDs.)
• Working distances of 2.5" to 5.0" without center shadow, with ~3.5" ideal working distance for excellent uniformity and high intensity, with short working distance version for working distance under 2.5"
