I noticed some of my downlighting falls just slightly short of a solid strike when illuminating sago palms. The sago is dark green, non-translucent, and not reflective. Low and wide, downlighting them is by far better than uplighting. If anyone can recommend a fixture that might give me more punch I would appreciate it. I hesitate to try 50 watt mr-16's, but maybe if I find a good fixture to house them and use filters to spread and diffuse them a little. I use Lunars mostly and the cast tree-lights, but I have to check if they are rated for 50 watts. Just curious if anyone has experience with bigger guns for downlighting.
