Hello fellow cultivators,
I am always building tools to assist me in comparing light designs and their needs/cost.
I have an excel sheet that allows you to input your total estimated CoB watts(CoB Voltage Multiplied by Amps), and returns an estimate of your expected heat watts(@45% CoB efficiency), and the amount of surface area necessary to manage the estimated heat watts.

**Unfortunately I am not allowed to share links due to the infancy of my account. If someone sends me a DM/PM I will provide it to them, and hopefully they will share it here in the thread below**
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
If you already have a favorite heat-sink material and source, you just need to identify the amount of surface area that material provides and make sure it matches the excel sheets estimated surface area necessary to manage your estimated heat watts.
For beginners or people who haven't decided what type of material and source or material they would like to use, the excel sheet also estimates the amount of 5.886" aluminum heat-sink necessary and the cost of that heat-sink material. These numbers are pulled from heatsinkusa and may vary in the future.
You can always check the heatsinkusa website and update the excel sheet according. You can also tweak the CoB efficiency as necessary, but it is recommended to always estimate efficiency at at least 10% below the actual estimated performance.
Note: The active cost estimate does not include the fan and power supply unit that would need to accompany the heatsink material.

P.S. Please be critical and provide feedback and data if available. I will continually update and improve the calculator, I'd like to see all of the communities favorite heat-sink materials and sources included.
Cheers,
