I have been using 10 watt lamp or LED equivalents for years. The most difficult part for a good designer is to get the budget necessary to use more softer and diffused light sources rather than fewer brighter ones. My go to is a 20 watt BAB or it's equivalent, and frosted or linear lenses.
I had a chance to play with the cast, FX, and other adjustable fixtures recently at the International Landscape Lighting Institute, Jan Moyer's Intense Course in Troy, NY. We were all very impressed the flexibility these fixtures bring to the design pallet. Talk about fine tuning a job, this is a whole new animal now.
