Do you guys think this information is accurate. I'm planning on adding a few to my car. How should I go about connecting them so i can control them with a switch??
Hope you guys can help.
Thanks in advance.
GENERAL LED HANDLING PRECAUTIONS
CAUTION: The light output from Super Bright Leds is intense enough to injure human eyes at close range. You should never look directly at the LED source for more than a few seconds.
CAUTION: LEDS are static sensitive devices. Observe static sensitivity handling precautions, such as wearing a grounded wrist strap when handling.
When forming leads, the leads should be bent at a point at least 3 mm from the base of the led.
Avoid damage to LEDS by soldering for no longer than 3 seconds with 700° iron.
LED life expectancy is based on current and temperature. You can expect our LEDS to last approximately 100,000 hours at 20 ma with ambient temperature of 20° C.
LED BRIGHTNESS versus VIEWING ANGLE
LEDS in CARS and BOATS
To use leds for 12 Volt applications you must simply connect a resistor in series with the led or leds. The led will drop some of the 12 volts and limit the current. See the Forward Voltage spec on the spec sheets for typical and maximum forward voltage, they're not all the same. Use a 1/8th watt or larger resistor soldered to the anode of the led and connect the +12 to the resistor. The chart below shows you the forward current for each color led with a single led in series with a 470 ohm resistor connected to 12 VDC. The current (and led brightness) will be slightly higher when the vehicle's engine is running because the battery charging system keeps the voltage up at around 13~14 volts. You can connect up to 4 red, orange, or yellow leds in series with each other and one resistor to power with 12 volts. The value of the current resistor must be lowered, depending on how many leds are in series. A maximum of 3 of the other colors can be in series across 12 volts, because of their higher forward voltage requirement. More 12 volt led replacements for some common car bulbs will soon be available on this site.
