are cfl bulbs good for plants?

CFL bulbs provide the light wavelengths that plant need for growth and produce much less heat than conventional fluorescent or incandescent bulbs. Compared to sunlight, CFL bulbs produce far less light intensity, so multiple bulbs may be needed to provide enough light for healthy plant growth.

CFLs are highly versatile and can be used in any setting where you would normally use incandescent bulbs. They come in enough shapes and sizes that you can use them for recessed fixtures, table lamps, track lighting or ceiling lighting.

All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast. ... Incandescent and halogen lamps do not require a ballast.

CFLs are fluorescent lamps that emit light from a mix of phosphors inside the bulb, and were designed to replace incandescent lamps (a lamp that produces light as a result of being heated). ... A light-emitting diode, or LED for short, is a lamp that emits light in a very narrow band of wavelengths.

Compact fluorescent light bulbs (CFLs) contain small amounts of mercury. A small percentage of this mercury can be released into the air if the bulbs are broken. Careful clean-up of broken bulbs can minimize the risk of mercury exposure.

CFLs: Compact Fluorescent Lights CFLs use about 70% less energy than incandescent bulbs. They also last years longer than traditional bulbs, and only cost about a dollar more per bulb. ... Plus, modern CFLs contain a small amount of mercury, which is very harmful to both your health and the environment.

The energy efficiency of CFLs may be significant, but unlike traditional light bulbs, there is a hidden danger sealed inside each little bulb that requires special handling and disposal. Mercury – a potent, developmental neurotoxin that can damage the brain, liver, kidneys and central nervous system.

Efficient. CFLs are four times more efficient and last up to 10 times longer than incandescents. A 22 watt CFL has about the same light output as a 100 watt incandescent. CFLs use 50 – 80% less energy than incandescents.

Just aim for about 150W of CFLs in Total Per Plant to Start, and stick to relatively smaller size bulbs if you can! If you want them to screw into regular light bulb sockets, use ones with a “medium base”.

In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. ... CFLs need a little more energy when they are first turned on, but once the electricity starts moving, CFLs use about 70% less energy than incandescent bulbs.

CFL types. Most of the CFLs sold are not full spectrum. Mostly they are in two color types: warm and daylight colors. And instead of indicating the color of bulbs when lighted, people use Kelvin to measure the light color (or also light temperature).

An incandescent bulb doesn't contain mercury, but it still has a higher overall mercury footprint than a CFL, thanks to the coiled tube's energy efficiency. ... 1 source of mercury pollution, and energy-intensive incandescents make those plants burn more coal than CFLs do.

Now CFLs, or compact fluorescent lamps, are slowly disappearing from stores. Home retailer IKEA stopped selling them in all its locations last year, and now manufacturer GE has penned a cheeky Dear John letter to the technology, saying it will stop making the bulbs in the United States.

Seedlings grow best when provided with light that provides both red and blue light wavelengths. Fluorescent full-spectrum lights work best because they provide the necessary wavelength and don't heat up, but an incandescent light bulb can work in a pinch. Incandescent lights primarily supply the red spectrum.

In reality, the bulb is burning out because it's overheating and they're lucky the bulb burnt out and didn't start a fire. CFLs could “puff” smoke or could “explode and cause a fire” if used in a fixture that doesn't allow for air circulation around the base, Smale said.

CFLs have a coiled tube instead of the round bulb you see in old-style light bulbs (incandescent bulbs). ... CFLs use about 75 percent less energy than incandescent bulbs. Saving energy helps the environment. Using less energy means less greenhouse gases will get into the air.

Since CFLs are designed to provide general illumination, the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.
