What happens if you use non dimmable bulb in a dimmer?
If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.
What happens if you use non-dimmable bulb in a dimmer?
Can any light bulb be dimmable?
The answer is yes, all incandescents are dimmable. They have the largest controllable dimming range from 100% full light, all the way down to 0%. Incandescents produce light by allowing an electric current to flow through a metal filament surrounded by inactive nitrogen and argon gas.
Can any red light be used in a darkroom?
Can I Use A Red Light To Develop Film? The only film you can use a red light when developing it is orthochromatic black & white film which is not sensitive to red light (red appears black in the images). However, most black & white film produced now is panchromatic and sensitive to red light, including a red safelight.
