What wattage range is typically recommended for bulbs in a darkroom?

The recommended wattage range for bulbs in a darkroom generally falls between 7.5 to 15 watts because this level of illumination minimizes the risk of exposing sensitive photographic materials while still providing enough light for safe movement and tasks. Keeping wattage low helps to maintain a controlled lighting environment essential for tasks like film development or print processing, where unwanted exposure can ruin the images.

Using bulbs within this wattage range helps to create a working environment that is dim enough to protect light-sensitive materials, but bright enough to allow for necessary visibility. The specifics of 7.5 to 15 watts strike an important balance—providing adequate low-level lighting for safety without jeopardizing the integrity of the photographic process.
