&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;=Basics=&lt;br /&gt;
*A Modular LED Unit Utilising [[COB LED]]s and some sort of cooling method (most likely water cooling, but air may be possible as well&lt;br /&gt;
*Can be paired with various Lens Modules for various effects\&lt;br /&gt;
*Main use case is for high level lights such as stagelights, light poles/ [[Light Cart]]s, and stadium lights&lt;br /&gt;
*High Speed Photography also requires very bright lighting so this may be of use for that&lt;br /&gt;
*This will also be more efficient than alternatives such as HID lights and other Gas Discharge Lamps (Outside of [[Sulphur Lamp]]s Perhaps (These are underdeveloped so their efficiency peak MAY be much higher than the current 15% efficiency (Which is slightly lower than LED&amp;#039;s 20-25% see [[Luminous Efficacy]]&lt;br /&gt;
&lt;br /&gt;
=Existing Open Source Designs=&lt;br /&gt;
*[https://www.youtube.com/watch?v=UJmbqwxXwGs A 10 LED Module made by the youtube channel &amp;quot;tesla500&amp;quot; ] (Did use a custom waterblock, but many alternatives are available online as pc watercooling blocks for cpu&amp;#039;s or graphics cards&lt;br /&gt;
*[https://www.youtube.com/watch?v=-vgNh3fLxJc A Similar Device made by the youtube channel &amp;quot;Sam Shepard&amp;quot; using more off the shelf componets]&lt;br /&gt;
&lt;br /&gt;
=Industry Standards=&lt;br /&gt;
*Truck Light Bars&lt;br /&gt;
*Led Light Carts, and Stage Lights&lt;br /&gt;
*Led Stadium Lights&lt;br /&gt;
*Although the modular approach is quite unique&lt;br /&gt;
&lt;br /&gt;
=Minimum Viable Product=&lt;br /&gt;
*Square Shape for ease of lens use etc&lt;br /&gt;
*modules of 1, 5, and 25 cells depending on scale needed&lt;br /&gt;
*Custom Milled/Etched PCB for soldering chips to, and water cooling block&lt;br /&gt;
*Connects to the [[Modular LED Light Core Module]] for power, control, and cooling&lt;br /&gt;
*Balanced Power Supply to the chips (Most likely via parallel if possible)&lt;br /&gt;
&lt;br /&gt;
=Basic Design=&lt;br /&gt;
==Frame==&lt;br /&gt;
*[[Modular Light Frame]]&lt;br /&gt;
&lt;br /&gt;
==Chips==&lt;br /&gt;
*Find the [[Highest Lumen Density COB LED]] chip you can afford, reasonably aquire, and use&lt;br /&gt;
*[https://store.waveformlighting.com/products/100w-cob-led-95-cri-full-spectrum-d65-6500k?variant=15865812484198 100w Chip, provides 10,000 lumens of 95 CRI] ~75 USD&lt;br /&gt;
*The above chip is also available in a &amp;quot;warmer&amp;quot; color if desired [[Modular LED Light Core Module]]&lt;br /&gt;
&lt;br /&gt;
==Water Block==&lt;br /&gt;
*Either an off the shelf [[Water Block]] (Most likely from a PC CPU/Graphics Card Part) or a custom machined part preferabbly copper or stainless steel&lt;br /&gt;
*Use either barb connectors or some sort of quick disconect fitting that lead to the [[Modular LED Light Core Module]]&lt;br /&gt;
&lt;br /&gt;
==PCB==&lt;br /&gt;
*Either Milled or Etched&lt;br /&gt;
*The Chips are Soldered Directly to this (Need to check if this will mess with the thermal preformamce&lt;br /&gt;
*Also contains the power in port that connects to the [[Modular LED Light Core Module]]&lt;br /&gt;
&lt;br /&gt;
=CAD=&lt;br /&gt;
*&lt;br /&gt;
&lt;br /&gt;
=BOM=&lt;br /&gt;
*&lt;br /&gt;
&lt;br /&gt;
=See Also=&lt;br /&gt;
*&lt;br /&gt;
