Unit emits more flashlight than the standard 50/50 light cube or half mirror, with around 80% efficiency. The system is not based on the Köhler principle as it is impossible to design a universal system to satisfy the various optical systems found in numerous microscopes. Instead, it utilizes general illumination. For light-hungry applications, higher ISO settings are necessary when employing flash for moving objects.An adjustable-speed fan is available as a separate item. Please use the drop-down menu.Universal dimmable LED/flash illuminator for the microscope.  Microscope modification is not required (except small reversible change in the Labophot 2, instructions - https://drive.google.com/file/d/1_aga06QOh5XWMaQomJmgkdC3oYJoT98e/view?usp=sharing ) . Non PWM dimmable 60w power supply  has a voltage indicator, US plug (EU plug depending on the stock) and inline switch, which allows you to disconnect LED at the any power level . Maximal flash head thickness of the updated model is 54.5mm comparing to the older version 46.5mm . All models have a fly-eye type collimating/diffusing lens, and the LED has a power output of 24W (110-120 Lm/W) and a high CRI of 97-98. The continuous duty mode is up to 20W (voltage to watts chart is included), but if you need higher output wattage for a longer period of time (e.g. for light-hungry applications, up to 24w), please check the heatsink's temperature!

It is highly advisable to use the fan, especially when planning to run the unit at high power settings for an extended period. The adjustable-speed feature allows you to customize the airflow, enhancing the overall efficiency and performance of the unit while helping to maintain optimal operating conditions over prolonged usage.
