Capacitor Based LED Tubelight Using 1 Watt LEDs
In this post I have explained the construction of a homemade 100 watt capacitive tubelight circuit using 1 watt LEDs. The idea was requested, constructed, tested and verified by one the avid readers of this blog Mr. Tamam. Let’s go through the entire discussion. Discussing the Proposed The Design I regularly visit your blog, and […]
How to Illuminate 1 Watt LEDs with Cell Phone Charger
Nowadays probably all of us have a spare cell phone charger lying idle in our cupboards or table drawers……so wouldn’t it be a great idea if we could employ it like a super bright 1 watt LED driver and illuminate our room with white cool moon light. Circuit Concept As we all know that a 1 watt […]
How to Make Powerful Car Headlights Using LEDs
In this post we see how to build an enhanced and efficient car headlight lamp using Pirhana LEDs. A car LED headlight is a powerful lamp built using high efficiency LED arrays, which creates extremely powerful headlight lamp for the car, along with a very high efficiency in terms power consumption. Using 4-pin Pirhana LEDs […]
