Choosing driver for diy leds

[benpoole28]

Having a hard time figuring out what driver to get for this project. Any help appreciated. I'm wanting to power 80-100 leds with the following specs.

I use the ldd-h 1000mA drivers at 14 chips a driver for what I do.

Do you use 3w or 5w leds? Seems like the 1000ma current are for 5w. I could be wrong through.

Those are not what I'm familiar with but seem like a much better option. The ones I was looking at are driver/DC adapters I guess. I wasn't aware you buy them separately. I'm assuming I would need a 300w power supply? 100ea 3 watt leds.

I use the 3w chips
The total load is dependant on the voltage applied to the chips.
I am running 55 chips on a 3.3a supply running 48 volts

This is a simple way to control led chips

Very nice. What is the piece in bottom right corner?

That is my diy inverter for power to my storm controller
