The cool tube is by far the best for moving air across the bulb. I made my own batwings using an old hood but I can say the area has never been as cool. LOL just as the name implies. I looked into the batwing reflectors you can buy with the cool tubs but they weren't up to my standard (not wide enough). Much better results with the DIY batwings. Here is a place that has some Grow Light Reflectors, Radiant, Sunspot, Vertizontal
