Roman, The hot box consists of two 25 watt globes fitted to a large foam container. The globes are wired to a dimmer switch which allows me to control the temperature. I don't need prescise regulation, more over temp protection. For example the heating turned off at about 40 deg. C (104F) and back on again at 20 deg. C (68F). I would love to hear about your incubator.
