100 W Led Light

mounted in a power supply box, equipped with a fan controlled by a heat sensor controller

magnifying glass was polished with sandpaper on the back for better focus

making it easily removable screws on the edge to be able to change / charge batteries

the future I will mount a power socket

2. CPU cooler from scrap desktop

3. fan from scrap power supply

5. 150W DC-DC Boost Converter 10-32V to 12-35V Step Up - 3$ from eBay

6. PCB thermostat with relay - 4$ from eBay

7. 100W led from eBay - 3 $

end sensor is mounted radiator, set me to start fan at 50 degrees

how heat detector works

We added the right holes in the radiator because it is not cool quickly enough

Besides I added a battery charge socket and plug the power supply from another source

I used a handle for furniture, stiff enough to support all consolidated overview
