Hi,

Yes, the WH7 can drive 4 lamps. The first and simplest way to connect 4 VHO lamps to one WH7 is to connect 1 bulb per set of wires. The WH7 has 4 sets of wires - each set is composed of one red wire and one yellow wire. Yupe..it will light, but it will not be very bright.

The other method is to connect the lamps in series-parallel combination. Basically, we will connect two lamps together in series so that it looks like one long 8 foot VHO bulb. Then, connect the two 8 foot long VHO bulbs to the WH7 -- each 8 footer is connected to two red wires and two yellow wires.

The third option is to use the WH8. Basically, a WH8 is two WH7 in the same package.
