Thanks Paul, 

But surely the output voltage needs to be higher?

Why can't you buy the "recommended" driver from the supplier of the lamps?

Because a driver came with each led and it only has enough power to do 2,not 4. I need one driver to be able to do all 4

why cant you use 2?

Because I am restricted with space above the leds

Beware of heat....

But you haven't told us what voltage your LEDs are :C

Manufacturers: Tridonic, Osram, Philips to name a few. You need a minimum of 22W, preferably 24W 350mA - just google the manufacturers, then decide whether they will fit in the space you have.

Not in a constant current driver - the voltage varies to keep the current constant.
