The best UV light bulbs are made by Sylvania and Philips. The downside of the story is that UV light bulbs of those brands are among the most expensive on the market.
The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.
The dark black incandescent type UV bulbs will work as they actually get hotter than the equivalent standard incandescent bulb of the same wattage, but the compact fluorescent type UV bulbs run too cool.
red bulb for the night time and white bulb pluse uv tube for the day.
UV lamp, also called Black-light Lamp, device for producing electromagnetic radiations in the wavelengths between those of visible light and X-rays. The Sun's rays are rich in such radiation, sometimes referred to as black light because it is not visible to the unaided eye.
Yes, some light bulbs, such as fluorescent and LED bulbs, can emit small amounts of ultraviolet (UV) radiation. UV radiation is not visible to the human eye but can have potential health risks if exposure is prolonged.
Non-UV light bulbs have the benefit of being safer for human health and the environment compared to traditional UV light bulbs. They do not emit harmful ultraviolet radiation, which can cause skin damage and eye irritation. Additionally, non-UV light bulbs are more energy-efficient and have a longer lifespan, making them a more cost-effective and sustainable lighting option.

Yes, artificial UV lights can be created using specialized bulbs that emit UV radiation. These bulbs are often used in tanning beds, sterilization processes, and scientific research. However, it is essential to follow safety guidelines as UV radiation can be harmful to human skin and eyes.

Bugs are attracted to the heat produced when standard bulbs produce and emit UV rays. LED bulbs are cooler and emit fewer UV rays, thus bugs are less attracted.
UV light is produced by various sources including the sun, black lights, tanning beds, and UV lamps. Specialized materials can also convert visible light into UV light, such as fluorescent materials in fluorescent bulbs.
UV bulbs are usually fluorescent tubes with the normal white phoshor powders removed. Heaters at each end of the tube excite electrons to 'boil' off the wires. A high voltage is applied via an inductor or choke across the tube ends which sets up a flow of electrons through the tube called a plasma. This is the 'electric blue' of a miniature lightning bolt and emits UV light.
The dark black incandescent type UV bulbs will work as they actually get hotter than the equivalent standard incandescent bulb of the same wattage, but the compact fluorescent type UV bulbs run too cool.
