How to make USB powered 7watt led Bulb at home .Reuse damaged LED bulb.
About This Video :-
In this video I made a USB powered led bulb at home by using old non working led bulb. no need to buy additional material from market. just one damaged led bulb is sufficient for this project. this bulb can run on multiple devices like : power banks, charging adapters, OTG power output from smartphones etc.
This Led bulb gives very bright light .I performed some tests to show the bulb's performance in the video ENJOY THE VIDEO.

VERY GOOD IDEA BRO...

[@Shahbazkhan-vu7by]

Heat will eventually make it less durable,, as leds are far off from heat sink it will be unusable for long time

[@TechnicalVampire]

Absolutely and it happened

Wah bete
I never used iron for ditache SMD Leds.

It will depend on power source

I have done the same process but all smd leds are being fused.

[@shreesdbn]

I was trying to do the same , and wanted to test the led with a 5 volt phone charger. The LED did not glow but also the charger doesnt work any more ! is it possible the charger gets short circuited due to a bad LED. ?

[@TechnicalVampire]

No, charger comes with short circuit protection . If the charger is very cheap price then it may become damaged

[@victorunbea8451]

The LEDs need a current limiting resistor to protect both them and the USB port. The value of the resistor depends on how many leds.

[@Eminem67345]

How much of time this bulb will glow by using powerbank ?

[@TechnicalVampire]

It will Depend on powerbank .
Suppose you have 10,000mAh powerbank so it will glow 5 to 6 hrs on that power bank

[@MovieNite27]

I tried making it but wont start , am i missing any part , checked +ve and -ve of led , all correct , usb line is also correct red and black tested uswd with lap top (5.4v)

[@TechnicalVampire]

Bro laptop does not provide the desired amount of power for this. it gives near 5 watts only or 5V and 0.5 amp. And if you connect higher load to the laptop usb port then laptop automatically turn off the supply for that port. Try it with power bank or with Power adapter. Also make sure that led's are fine.

[@anshurajput9588]

can i use new 9 watt led bulb instead of repairing old led bulb

[@TechnicalVampire]

Yes

[@salamshaktisingh3365]

[@ahinvention5734]

[@TechnicalVampire]

Poroblem find kro

[@gardeningsetup436]

how it will run with out heat sink

[@AJ-or9pn]

Bro I apply your ideas it's work. But I got one problem.
I connect 6 led with 3.7volt mobile battery but I don't know why led are so heating and remove thos solderin wire, when I connect a resistor with led, the led are not heating but 2 led are not glow when I connect a resistor.
Please give me a idea
Sorry for the my bad English

[@TechnicalVampire]

It OK bro. Your English is nice.
You shoud use thick copper wire and don't use resistance
Thick copper wire will transfer the heat

[@AJ-or9pn]
