Mightex’s PLS- series precision LED spotlights are a general-purpose light source that can be used where uniform and high-intensity illumination is required. State-of-the-art high-power LED emitter and a proprietary high-NA multi-element aspherical optical system combine to produce a high-power, uniform illumination spot with a highly-delineated edge. Close range version for working distance of 10 cm or further.

Mightex’s precision LED spotlight consists of a state-of-the-art high-power LED emitter and a proprietary high-NA multi-element aspherical optical system. The result is a high-power, uniform illumination spot with a highly-delineated edge.

Mightex’s PLS- series precision LED spotlights are a general-purpose light source that can be used where uniform and high-intensity illumination is required. The projection lens at the front of the spotlight can be slid and locked to focus the illumination pattern at different working distances. With the standard projection lens, the spot diameter is linearly proportional to working distance.

The LED emitters are mounted directly on the metal base of the light source which also features an integrated heatsink. This configuration minimizes thermal resistance between the LED emitter and the heatsink, resulting in better heat dissipation.

Multi-chip LED emitters (i.e. Type-B) have been added to the product portfolio. Some of these 7 W to 15 W LEDs have total optical power exceeding 500 mW, doubling the power of a single-chip LED. Such Type-B models with higher powers (7 W and higher) feature a cooling fan, and have a different form factor compared to Type-A models. Please examine the installation drawings carefully. Power supply for the cooling fan is included in the price of the Type-B precision LED spotlights.

The precision LED spotlight includes a 2-meter cable with two bare-wire terminals at the end. The light sources can be driven by Mightex LED controllers or other LED controllers and current sources.

IMPORTANT : (1) LED’s can ONLY be driven by a constant-current source, and NOT a voltage source (e.g. a battery, or a AC/DC power supply etc.); (2) Please always verify LED’s current rating first before applying current to the LED, and please always make sure NOT to apply current that is above the LED’s current rating.

Precision LED Spotlights with Uniform Illumination

Abdelfattah AS et al., Bright and Photostable Chemigenetic Indicators for Extended In Vivo Voltage Imaging – Science (2019)
Abdelfattah et al., developed novel chemigenetic indicators for in vivo voltage imaging in neurons. To illuminate their indicators, the group used Mightex’s Microscope LEDs.

Crandall SR, et al.,  Infrabarrels Are Layer 6 Circuit Modules in the Barrel Cortex that Link Long-Range Inputs and Outputs – Cell Reports (2017)
In this work, Crandall et al., used Mightex’s Microscope LEDs to optically stimulating different neuronal pathways connecting to pyramidal neurons found in L6 of the whisker somatosensory cortex of mice.

Higgs MH, Measurement of Phase Resetting Curves Using Optogenetic Barrage Stimuli – Journal of Neuroscience Methods (2017)
To study phase resetting curves in vivo, Higgs and Wilson used Mightex’s Microscope LEDs to establish whether their novel method of optogenetic barrage stimulation would work during extracellular spike recordings (a recording method often used in in vivo experiments).
