Using Aluminum Strip Heatsink for Hi-watt LEDs instead of PCB

Last Updated on June 1, 2026 by Swagatam 16 Comments

20131225 050828 2

Whenever we come across using 1 watt LEDs or other higher watt LEDs, we are always advised to use high grade aluminum based heatsinks for safeguarding the LEDs from heat, and for acquiring optimal performance from them. Double Side PCB can be Costly However as we all know such PCBs are highly costly and could […]
