Bahut badhiya reply de rahe ho Dhanyawad
Sir mere paas 6 watt 60 led he round wali 4 volt ki, wo heat bohot hoti he , usko konsa resistor lagau , please reply sir
6.8 ohm 2W ke 3 Resistor parallel karke LED ke series main lagaye
Ya fir 2.2 Ohm 5W Resistor serise main lagaye
@@hpdiyprojects sir dono mese long time aur accha battery backup kon dega
Nice information.. 👍
Bahut badiya bro
Gjb bro...
bhai 4 volt, 3 led ko series mein lagane se 12 volt se chala sakte hain?
Yes just use current limiting Resistor in serise
Great information thanks
1. Sir 12v cob led 12.6v pe chalane ke liye konsa register use kare?
Aur
2. Sir 4v cob led 12.6v pe chalane ke liye konsa register use kare?
12.6V pe 2.2 ohm ya 4.7ohm 1W or 2W use karo 12V cob ke liye
Or
12.6v par 4v cob 47 ohm 5W or 10W lagela lekin issme loss jyada hain
1.5 to 2w LED ke liye Resistor se 7-8W loss hoga 10w loss 2w ke led ke liye
But you can use LM2596 buck converter and set at 3.8V then you get Awsome result....or use lm7805 Regulator has cost 10₹ only

Can you tell me for 4v Bar COB Led, if need to run on 5v, as per your video end screen, you have mentioned 4.7 ohm, is it 47ohm, 470ohm , 4k7ohm, 47k ohm, please tell me in the format which i have told, it causes confusion with what you have mentioned in the last screen.
Bar led ke liye 6.8 ohm to 10 ohm use karo
nice ☺️
Sir ye 2.2 ohm 1 w ki resistance lagale se bhi heat ho rhi h or wire bhi heat heat ho rha h please reply sir
Lithium Battery 4.2v to 4.4v hota hain to aap 4.7ohm 2W ka Resistor use karo ya
2.2ohm ke 2 Resistor series bhi kar sakte ho
Heatsink or thoda thick wire use karo copper ho to behatar
Bhaiya woh cob led 4 volt ka lamba wala patla uska dimensions bataye thora....bohot meherbani hogi apki thora dimensions bataye
Very useful video
Thank you
Bhai mujhe cob light ko 10000mah ke battery Se connect Karna hai toh konsa ohm/watt ka resistor lagega please batayi
2.2Ohm 2W Resistor for 4.2V battery
Agar battery bank usb se jalana hain to video ke end main chart diya hain
3.7 volt मोबाईल बॅटरी के लिये TP4056 का इस्तेमाल नही किया तो चलेगा क्या
3.7V battery ke liye 4.2V full charge hain
TP4056 max 4.2V deta hain battery ko
Agar aap 5V mobile charger se charge karoge to overcharged hoega or battery फूल jayega
Agar apko tp4056 nahi lagana hain to direct charger se charging ke liye aap 1N4007 diode serise main lagao or jyada der charging mat karo(ye unsafe tarika hain li ion battery ke liye agar battery main inbuilt overcharge protection nahi hain)
भाई मुझे तो नही समज मे आरहा है की मोबाईल के बॅटरी मे ओव्हर चार्ज प्रोटेक्शन है या नही.
अगर मोबाईल बॅटरी मे ओव्हर चार्ज प्रोटेक्श है या नही है दोनो कंडिशन मे हम TP4056 लगा सकते है क्या
Ji. I have an LED cob that is rated 3.7v to 4v....Can I use 3.7v 18650 battery directly without resistor? I do t understand resistor that's why asking.
Yes we can connect 3.7V battery 🔋 for COB Resistor but cob produces high amount of heat so life of cob will be very low... Resistor is component that ressist current flow in cob.. led works on constant volt and constant current....
@@hpdiyprojects thank you. What resistor to use for 4v Cob + 3.7v battery?
Use 2-5ohm
3.7v ke battery se 4v ka led strip jalane pe bahot heat ho raha hai. Iske liye resistor lagane se kuch kaam hoga? Agar lagane se accha hoga toh konsa lagau please boliye sir.
2.2 ohm 2w Resistor or 4.7ohm 2w
Kaha se khride hai bro
Bhai smd. Light. 4v sea calani sea..
Bohot hit hote sea... Kiya karu bulo..??
Direct Li-ion Battery se chala rahe ho to 2.2ohm ka Resistor 1W serise main lagao

hei brother..
im in trouble 🥺
TL 1073-2 Doesn't Glowing With 1 Ohm / Any Resistor..
But Without Resistor its Working.
1+ = 4 V Supply Positive
-= Negative.
Is There Any Solution?
Use 3 resistors in parallel of 1ohm/2W
Led glow 80% of his highest brightness
At 4V supply or battery
Led works best on 3.3 to 3.6v but at 350mAmp current so led driver is required...constant current and voltage
@@hpdiyprojects Thanks Brother.
Brother Which resistor Will be perfect for 4 Volt, 13 Waat Cob LED?
I Want better Glowing With better lifetime 🥰
भाई 12v battery se कैसे चलाए

12 v ke liye kitne ka resistor lagaye bar cob led mai
COB LED 3.8V 550mA ki hain 2W
12v Keliye 5w se 10w ka 33ohm ya 47ohm ka lagega 10₹ se 20₹
Isase acha aap LM7805 Regulator 5V lagao 10₹ main milega or serise main 2 ohm 1W ka resistor 1₹ lagao isase battery jyada drain nahi hogi
Nahi to aap buck converter use kar sakte ho min 60₹ cost aayega (12v to 3.8v directly)
Konsa Resistor kaha lagaye ye dekhneke liye video ka end dekho
Bhaiya main 4 led strips 4v ke use karne ka try kar raha hoon, switch on karne ke saath hi jal ke bandh ho ja rha hai aaur wire garam ho rha hai. Main kya kar sakta hu isse thik karne ke liye?
हिंदी के लिए नीचे देखो...
use Resistor in serise 2.2 Ohm or 4.7 ohm 1W or 2W for Current limiting ... if you use BMS Then this problem happen...BMS cutoff the LED supply... Don't use old mobile battery BMS board.. For 5 strap at least use 3A to 5A BMS... may be TP4056 work fine if same problem then remove 1 strip...
304 / 5,000
हिंदी
करंट लिमिटिंग के लिए अनिवार्य उपयोग रेसिस्टर 2.2 ओम या 4.7 ओम 1W या 2W ... यदि आप बीएमएस का उपयोग करते हैं तो यह समस्या होती है ... बीएमएस एलईडी आपूर्ति को काट देता है ... पुरानी मोबाइल बैटरी बीएमएस बोर्ड का उपयोग न करें .. के लिए 5 स्ट्रिप कम से कम 3A से 5A BMS का उपयोग करें ... TP4056 काम ठीक हो सकता है यदि वही समस्या है तो 1 स्ट्रिप हटा दें ...
@@hpdiyprojects bhaiya thank you reply ke liye. Main tp4056 hi use kar raha hoon, mujhe lagta hai mera soldering thik nahi hai, jab wire haat se lagata hoon tab thoda blink karta hai lekin switch mein lagakar on karne ke baad jal nhi raha. Maine multimeter se check kiya aur mera switch ekdam theek thak hai.
Tp4056 par motor chalanese uska mosfet Short hota hain plz use diode in serise with motor...
I already have such a problem on my Tp4056
Kabhi kabhi overvolt hone se bhi blink karta hain
@@hpdiyprojects haa bhaiya iska koi solution hai kya high power led chalane ke liye??
गोल वाला cob light कितने में और कहा से लिया अपने online ya offline
Online available hain lekin cost jyada hain local market main apko 15 se 35Rs tak mil sakta hain
3W 3.7V 1000mA 300lm Led COB Light
Mobile charger k se on karo
What is name or size of wire
Selection of Wire thickness depending on amount of current flowing through it without heating itself...
1 S.Q.M.M. wire sustain 9 to 11A current maximum copper...but costly and thick...
For 1 to 2amp you can use speaker wire( 2 core ribbon wire) copper preferred...
Use Current wise core thickness chart on Google so you can easily select perfect wire...
@@hpdiyprojects max 3 ampere
I would like to know wire used in video
Any online purchase link
@@hpdiyprojects nice information thank you

Sir Mai 4v round wali cob led 3.7v 6000mah battery pe chala raha hu lekin ye 1 hour k pehle hi full down ho rahi hai kya karu....kuch upay bataye
Resistor Lagao 2.2 ohm ya 4.7 ohm ka
Ya fir
1. Transistor Dimmable circuit ka use karo
Main jald hi video upload karunga
2. Round cob 3.0V par chalao
3. CC module use karo. 5A par set karo
6A *4 =24W
Or round COB 2w ka hain
Theoretically 12Hr chala chahiye
Cob heat ke vajaha se Wattage west kar raha hain apka
Which battery is that 6000 mah???
@@hari_sn5331 yes
Those stars are Mc pcb. Not heatsink.
Konsi Site se liya hai sab ?
Hit sing kaise lgaye
Purine bulb ka lagaye ya fir local market se kharido.. heat sink pest lagakar super glue se chipkaye.
@@hpdiyprojects hit sing lgakar v fayfa nahi hai LED bulb ka brightness km ho jata hai 1 do din chla ke
Hamarey liye mange light
Mujhe order dena h😊
Price Kay hai
Apke local market main check Karo
15 se 25 rs max
Mujhe bhi a chahie parjesh karna hai aapse
Rate bhi batao Na bhai

Very very very very very very very very good good good good good good good good good
battery backup bhi to batadiya hota 😢😢
Round wali led bekar he wo bahut jyada heat Hoti he wo plastic Ko hi jla deti he
Round me bhi duplicate aa rahi hain...plz check while buying...
Plz use proper heat sink and Resistor...
I Used it 24x7 in last 3-4 months.... thoda heavy heat sink use karo ya fir 3.2V pe chalao
don't used it at 5V without Resistor....
Sir heat sink to use kre par heat sink ki heat batterys Ko bahut jyada garm kar deti he unke fatne ka khatra bna rahta he
Use 2.2 ohm ka Resistor use karo Or battery se duri bana ke rakho
buy kaha se krna h bro
