Go for the ones with a single led rather than the ones with multiple LEDs.

Additional info

There is one gotcha with the cheap LED floodlights

They come pre-wired with around 1 foot of 3 core mains cable

The mains wire is relatively thin (outside diameter 5 to 6mm - it only
has to supply 30W) and therefore the bush into the back of the unit only
accepts cable of this diameter if you wish to replace the short length
of supplied cable.

The units can be easily dismantled and they have waterproof caskets
between mating halfs.

The back box on these lamps is relatively full of the mains to DC
converter and the mains cable is crimped to the input wires of the
converter. There may not be enough room to use a chock block if you want
to remake this connection. Soldering with heat shrink or re-crimping may
be necessary.

Alternatively you may need a waterproof connector or box of some kind
to join your exiting wiring to the pre-wired floodlight.
