Key Insights
What does a 1.5 kW LED mean in terms of brightness compared to typical flashlights?
A 1.5 kW (1500 watts) LED produces extraordinarily high power, far exceeding typical flashlights which range from 50-700 lumens (roughly 1-20 watts effective output); this creates extreme brightness akin to a 'small artificial sun,' while standard high-output flashlights emit 500+ lumens.

Why is a cooling system necessary for a 1.5 kW LED?
High-power LEDs like 1.5 kW generate immense heat that can damage the diode or reduce efficiency without active cooling; the YouTuber's design addresses this to enable sustained operation at such intensities, unlike low-power LEDs in standard flashlights.
