MONOCHAIN-9 series LED modules are designed for backlighting surfaces uniformly at MEDIUM distance (14-20cm) between the LED and surface. We use the highest quality NICHIA LEDs from Japan and select only the narrowest bin available – 1/16th or 1 STEP MacAdam. Available in a choice of 5 standard colour temperatures (2700-5000K) having color rendering index (CRI) Ra85. Also available in high CRI version >Ra90. The modules are designed for long term professional lighting applications and perfectly suit for lightboxes, channel letters or curved lighting applications such as cove details. Due to the 155° wide beam angle optic lens, light is distributed more evenly inside channel letters and lightboxes. Consequently, this enables up to 2 ~ 4 times fewer LED modules for the same lighting installation compared to regular LEDs. Aluminum housing operates as radiator for better heat dissipation out of the LED die, which ensures extremely long lifetime and lower light degradation throughout the operating lifetime.
