This floodlight is different from the earlier ones in that it is based on a single flatter housing with both the LED and the ballast mounted in the same space. This particular light came supplied with a 20W green LED and matching ballast which is simply heatshrink sleeved and glued in the light.
The LED module is the common 10×10 array which is used in the 20/30/50 and 100W LEDs with a differing number of LED chips in the array. In this 20W version there are 20 1W chips mounted as two series lines of 10 chips. These strings of chips appear to be wired in parallel giving a probable voltage of about 30V at 700mA.
When I purchased this light I chose the one with green LED chips as I think it would look quite nice as a tree uplighter.
As with all Chinese lights like this it’s a good idea to check the integrity of the earthing to the casing. Once again the unit has been supplied with a very short flex just 7″ (170mm) long. (Which is actually quite annoying!)

I rig up a 400 watt, 48V solar panel to charge a 1970′s electric car. This is direct charging, no use of an inverter, AC power, wall power, or other battery charger.
The sun shines on the panel and creates current that goes through a solar charge controller straight to the batteries.
Panel is sized to recharge the batteries in 5 hours of sun from a typical 50% battery discharge.
