Thank you @rmm31 brother, your comment is really inspiring. LED light components are often thrown away as unnecessary, but with the right knowledge and skills, they can be reused. I tried to prove this by making an effective and long-lasting light. The LED chip I used here costs 10 tk in the market. And the heatsink I used to modify it costs 40 in Bengali tk. The price may be more or less depending on the location.

Thank you for your valuable feedback. If the video is easy to understand and understandable, then that is my success. I hope to be able to share more such projects with you in the future.
