My solution is not very romantic, so debated even sharing. I have one 500 watt halogen spot light on either side of my deck directed at the deck. It is almost like it is daytime when both are on. My RT also has the built in light, which does not put out huge amounts, it does illuminate some of the corners of the grates where shadows from the lighting is created. If I am at my mom's house cooking for her, it is not the same. No lighting at all. I usually use a flashlight or my smartphone flashlight. I had one of those minor head light type devices, but seemed to have lost it.
