What is the ohm on this?

Photoresistors are special resistors made of semiconductor materials such as cadmium sulfide or cadmium selenide, and their working principle is based on the internal photoelectric effect. The stronger the light, the lower the resistance value. As the light intensity increases, the resistance value decreases rapidly. Bright resistance: 5-10Ω, dark resistance: 0.5MΩ. Thanks.

Will these go below 200 ohms with a bright enough light source?

Dear customer, so sorry that they won't.

I need the very low 'on' state resistance that this provides, but need higher dark resistance than 1/2Meg, 5Meg or higher. Anyone have a part number?
