Do You Need a Resistor for Led Bulb for Tail Lights?

change the led lighting fixtures fixtures from side to side see in the event that they artwork,if no longer positioned previous 1157 bulbs back in in the event that they do artwork with previous bulb you are transforming into gotten the incorrect bulb.they might desire to be the right relacment eqivelent.turn alerts many of the time are a double fillament bulb. I certainly have been wrenching maximum of my existence and electric is mysterious somtimes. solid success!

1. Do i need as much wattage led bulb as normal halogen ?

No, you use 1/6 to 1/10 the watts. LED's are hard to compare, different manufacturers drive the LED's harder than others. (CFL were a little easier, but manufacturers were a little deceptive to claim higher savings.) Really look at the lumens you are looking for, if you have a 60w Edison bulb it probably produced 600 to 800 lumens (a long life bulb will have lower light output). Do watch the color temperature, a halogen bulb will typically have a color temperature of around 3000 degrees Kelvin (3000k), a traditional Edison bulb is around 2700k, if you buy something that says Bright Daylight 5000k or really anything above 3500k it will have a lot of blue output and you might really be unhappy with the result.

2. Video shows 9-year-old boy lighting LED bulb with his bare hands

A shy 9-year-old from Kerala, India, is suddenly in the spotlight after his family discovered he can light up a LED bulb just by touching it. Abu Thahir claims he discovered the bizarre skill when his father, who is an electrician, brought home a bulb from work. The boy is causing a buzz on social media ever since his aunt posted a video showing the amazing deed. His family claims his skill is genuine, and experts said his body might be acting as an electrical conductor due to a high salt content in his sweat. "People who sweat more usually have a high salt content in their body. If the level is unusually high, their bodies could conduct electricity," said expert Joshy K. Kuriakose to The Week. "If you connect the two leads of the rechargeable bulb with a wire, it will light up. Thahir's body is conducting electricity like a wire," Kuriakose explained. According to The Mirror, the father considers it as a gift given by God to his son and has accepted it without any complaints.

3. Is it safe to use a 28W LED bulb in a MAX 15W lamp fixture?

It really would be helpful if you would provide more information, especially the specifics on the light bulb.But - assuming the bulb draws 28 watts (and it is not the equivalent to a 28 watt incandescent light) then no, this would not be safe

4. Considerations for converting a LED Bulb from AC to DC power

Your calculation is incorrect. When you connect LEDs in series, the voltage required increases, but the current through the string is the same as for 1 LED. (The same electrons are flowing through all LEDs).So if 1 led requires 8mA at 8V, then 5 LEDs will require 8mA at 40V. Two of these strings in parallel would require 16mA at 40V (if your math for 1 led is correct).An easy check you could have done is to calculate the wattage. 450mA at 40V would be 18W, where it should be around 5. Your initial assumption of 8V and 8mA for 1 led would give a wattage per led of 64mW. So for all 10 leds we are looking at 0.64W, which is not correct. Again it should be around 5W.You should hook up the driver again, and adjust it until 1 led is drawing 0.5W. Then redo the subsequent calculations with the current and voltage you measure.

5. Have you purchased a 5 watt e-autoworks LED bulb for tail light?

Here in the uk it is illegal for tail lights to be as bright as brake lights. Regards. h

6. How many watts led bulb could replace a tubelight?

12w to 18w bulb can replace standard 40w Tubelight. But light spread for tube and bulb is different

7. Do I need to remove the ballast to use an LED bulb?

It depends on the lamp.Some require a working ballast to operate.Some operate on line voltage.It is important to know. The information will be on the lamp or packaging
