So, it is starting to get rather cool around here, especially at night. My fermentation chamber has been hitting the mid-50s in the evening. I have a digital Johnson A419 but have it on the cooling portion and wanted to figure out a heating source to keep it in range.
Anyways, I recently purchased a cone lamp fixture and a 60 watt blue incandescent bulb from a local pet store. I have left it on for a day and the bulb really heats up the freezer rather well, but.... I am a little worried about the light that it puts off. It is a soft blue light but I know its still putting off UV and UVA rays (as indicated by the box). Any suggestions on another alternative or ideas on having a blue bulb rather than a typical white bulb? Should I not be too worried with the blue bulb?
This bulb will get the freezer working a little more than usual but better than stalled fermentations.
