to get the correct light output from VHOs I must run these in series, assumingly like this:
however there are 4 wires on a wh7, a vho requires 3 red and 1 yellow..so in series 2 vhos should get 3 red one yellow, and 1 remaining red must be capped.
I'm assuming having all 4 wires running the bulbs causes extreme heat and melts the endcaps..is that what happened to you steve?
