Looking for info on making a vertical cooltube suitable for a 1000w bulb. Ideally an 8"dia tube that can withstand the heat. Will be using 500 cfm duct fans to cool, duct fans are 8" dia... can i reduct that to 4 in and use still use the 8" fan? can the bake a round sustain the heat a 1kw will produce? i have read both statements, wondering if anyone has done it.
