Here are a few bulbs I have tried. Very subtle difference with shadow and how much the bulb fills the punched out hole. What do you think. Before you say it I know the case and glasses are dirty. Just got the case and haven't had time to clean it yet 1. 50 watt LED 2.5 flood 75 watt LED bulb 75 watt 3.5 Flood 100 watt 5000k CFL. Looks worse then it is. Camera caught the glare. It sticks out about 2.5 inches like some do.
