I want to add a 5" Unity spotlight to my 39 Ford. It will be bumper mounted on the right side. I want to install the brightest flood light type bulb as I need it to light the road. Anyone have any experience with 5" floodlight bulbs? Like to know what you used. 50 watt seems to be normal size, but what does the beam look like. I saw specs in degrees up and down describing the beam coverage. I want to run just one light for now to see how it works. The 12v halogen bulbs with the stock reflector are not adequate. The stock bugeye original headlight lens distorts the light and does not send it down the road. Beam looks very round, high and wide. Lights up trees above very nicely.
