All Customer Questions
Question
I would like to run 10-25 LEDs of 12v power supply and be able to control light intensity with a controler or pot. Any Ideas? - by Tim (Pasadena, TX)
Answer
You'll need to use PWM (pulse width modulation).
Question
Are these High Power 1 watt LEDs more brighter than the LED Flood lights
Answer
They use the same LED, just a different lens to disperse the beam.
Question
What type of wire and gauge should I use with High Power 1 watt LEDs - by Bob
Answer
I think 18 gauge would work just fine.
Question
Can you explain why you want more flow by using all for post? is 3.3 the most you can put to them? - by Bob
Answer
You don't have to use all four posts, but if you do, the amperage draw is spread out more evenly.
Sorry, I don't know what you mean by "3.3"

Question
how hot do they get with all series will say 13.8 to 14 volts
at 350 ma do you need a heat sink to keep them cool - by Chauncey (Baker, Louisiana)

Answer
This products has a built in heat sink. You will not experience much heat with this product, however mounting them to metal will aid the heat dissipation.
Question
A catalog that I order from at work sells these same things in 3 & 5 watt versions. Since I have no use for 100 of them(min order), do you plan on selling these? Thanks! - by Eric (Fort Wayne, IN)
Answer
not yet.
Question
How big of a resistor do these require or how many must be wired in series for 12v to be directly applied? - by Brian
Answer
One LED on 14 volts would need about a 33 ohm / 6 watt resistor. No one makes a 6 watt resistor, so you'd have to use a bunch of smaller resistors to do this.
It is really not practical to use a resistor for a high powered LED.
You could wire 4 in series on 14 volts... 14 / 3.5 = 4

Question
how do i get these to work on a 12-14volt auto electrical system? - by addiction2bass (indiana)
Answer
Either a really big resistor, wire them in series, or use a voltage regulator. Or just use the ones that are 12 volt ready and already have a voltage regulator.
Question
are these water proof? - by Jason (Spokane, WA)
Answer
No these are not waterproof. They are just the raw LED module.
Check out our High Power 1 watt Waterproof LEDs which are nearly indestructible and ready to work on a 12-volt system.

Question
Do you have detailed spec sheet on these LEDs?
What is its brightness in lumens? - by gamas (scottsdale)

Question
Do all four posts have to be wired up, or just two? I'm looking to replace six square LED's in my motorcycle blinkers.
Answer
Just two is ok. But the reason there is four is to allow more current flow.
