Ive got a 358L (~95 gallon) chest freezer which I am wanting to use as my fermentation chamber. Ive read about using a light bulb to buffer the chilling of the freezer as my temp controller doesn't have increments short enough (less than one minute) to allow it to maintain an even temperature around where I want it to be. What wattage would I be best to start with do you think? I'm thinking I will just have the bulb kick in at the same time as the freezer on the same circuit to simply buffer the effect of the freezers cooling/freezing cycle. Does that sound the easiest way to go? The insulation is good so I don't expect it to cycle on and off very regularly, its holding 5C as a fridge at the minute and clicks on for at most 5mins every 60 to 90mins.
