LED Driver Help! Answered

So I have four 10 W LED's and I want to run them all together off of a led driver but I'm not sure what type of driver I need to get.

My led's specs are.

Color: cool white
Luminous flux: 750LM
Forward voltage: 9-12V DC
Color temperature: 6000K-7000K
Forward current: 1000mA
Power: 10W
Lighting angle: 160°

So if someone could help me with wiring it would be greatly appreciated. I've worked with little throw away led's and risistors but I wanted to use some sort of led driver, or constant current device on what I'm doing, but I don't know how they work.

I'm just trying to get something that will run all the led's and be cheap

You are better of using 4x 10w led driver like this:http://www.ebay.co.uk/itm/High-Power-10W-LED-Lamp-Driver-AC-85V-265V-DC-9V-12V-/160698478560?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item256a602fe0

You just split the main supply to them, they will regulate the power to the LED and they are relatively cheap. Instead of using 40w unregulated supplies.

You know 4x 10w LED is a lot of light.

Yeah this is what I ended up doing it was a lot cheaper than getting a 40 W driver. Yes, this is a lot of light it is incredible how much light comes out of such a small piece. I want to buy a 100 W for a flood light for bowfishing but I don't really wanna pay the hefty price for one.

You know 100w is what people use to light up big areas? It will be far too much light for your fish, lol

Have you ever been bowfishing? There is no such thing as too much light when it comes to bowfishing. You light up the water to see the fish at night the more light the better.

No I don't fish at all but you may have problem powering the 100w led if you no access to main power. You can bring a spare car battery or something but I don't think it will last that long.

You use a generator. Right now I use a 2500 W generator with 500 Watt halogen flood lights but if I got a couple 100 W leds plus the usual halogen lights I could have a lot more light while using only a little more power. But I heard the leds don't cut through the water as well as other lights.

you need a 40W led driver. You'll have a hard time driving that off batteries for long (you can, but it will die quick)https://www.instructables.com/tag/type-question/?sort=RECENT

they have battery capable and househole line voltage converters.

There's no way you would run a 40 watt led with a resistor easily, safely, or cheaply.

If on battery I'd run them each on a individual 10w driver boards.

Okay does it have to be 1000 ma constant current? Since that is the forward voltage.

The CURRENT is 1000mA, it will need to have 4x12V drive capability.

So I need a 40 W 48 V 1000 ma driver?

current = power drawn. think of the inside of an led as a special semiconductor resistor of variable value. In order to ensure it gets the right current all the time, you need to actively drive it with a regulator rather than just setting a fixed voltage, because it will change slightly.
