Here is a comparison for lumens that should help you, the Sunspot 64 is meant to replace the PAR64 bulbs on large (i.e. 737, DC-3, etc.) aircraft and are a bit large for an RV. The Sunspot 46 and 36 lights are equivalent to PAR46 and PAR36 bulbs found on light singles:
PAR36 Size Sunspot 36HX 100W Incandescent 30W HID
1500 lumens 1200 lumens 1800 lumens
PAR46 Size Sunspot 46 250W Incandescent 50W HID
6700 lumens 4600 lumens 4500 lumens
Note that the lumens given are only what ends up directly in the beam, there is light that goes off at other angles that is not included in the above numbers.
