Are high pressure sodium lights dangerous? High-pressure sodium lights often are used for street and highway lighting. When these lights are turned on, they can produce potentially harmful levels of ultraviolet radiation. However, cracked bulbs or covers can expose workers to harmful UV radiation, often without an individual even being aware.
Are high pressure sodium lights bad for your eyes? High pressure sodium lights have made indoor growth of crops possible, but without the proper safety precautions these lights can do serious damage to the human eye. The damage done is often times irreversible so it is imperative that people working in grow rooms take the proper steps to protect their eyes.
Are high pressure sodium lights a fire hazard? Different Kinds of Grow Light Bulbs and Fire Safety
Thankfully, there are now LED grow lights available, which are not only are less of a contact fire hazard but consume less energy too. High-pressure sodium (HPS) lights: Fluorescent grow lights. Metal halide lights.
Can you touch high pressure sodium bulbs? While LEDs are fine to touch with bare hands there are plenty of bulbs that you should not have any skin contact with at all. These bulbs are mainly, but not limited to: Incandescent bulb. High-Pressure Sodium (HPS) bulb.
Are high pressure sodium lights dangerous? – Related Questions
Do high pressure sodium lamps explode?
The Sodium in these lamps is a highly volatile substance. When exposed to air the sodium may explode.
Can you replace high pressure sodium bulb with LED?
While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.
How long does a high pressure sodium bulb last?
High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours).
Do high pressure sodium lights emit UV?
Unfortunately, the strength of UV light can be detrimental when used in the wrong way. High intensity discharge bulbs like metal halide and high pressure sodium lamps emit UV radiation.
What happens if I leave my grow light on 24 hours?
The answer to the question is no, it is not recommended to leave your grow light 24 hours a day, because this will force plants to grow quickly. It is ideal to keep a grow light on for about 12 to 18 hours. Too much light in various growth phases can interrupt a weed plant’s natural process of growth and dormancy.
Do LED lights get hot enough to start a fire?
Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.
How do I dispose of high pressure sodium bulbs?
High-intensity discharge bulbs contain hazardous mercury and must be recycled at a free drop-off mercury lamp recycling site. HID lamps come in a variety of shapes and sizes.
How do you troubleshoot a high pressure sodium light?
The most common problem with a high pressure sodium light is the bulb. The first course of action is to simply change the bulb. Observe the interior gas tube for any signs of discoloration. If the tube is black, the bulb is definitely burned out.
Do high pressure sodium bulbs need a ballast?
HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. HPS lamps do not contain starting electrodes. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.
Where are high pressure sodium lamps used?
High pressure sodium lamps are used in outdoor lighting of streets and parking lots and in indoor settings where color rendering is not critical. These indoor settings include warehouse and shipping areas and some manufacturing areas.
Which lighting scheme is best suited for room with high ceiling?
Suspended Lights. Lights which hang down for more than a few inches are called suspended lights. These lights are ideal for rooms with high ceilings.
Why is HPS better than LED?
The heat per watt is far greater with an HPS fixture compared to LED. This technology is far more efficient in transferring energy in to light, as it produces less heat and has a higher wattage equivalency to HPS (600w vs 1000w).
Why does my high pressure sodium light go on and off?
A high pressure sodium lamp cycling on and off usually indicates the lamp has reached the end of its normal life.
Which is better HPS or LED?
LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light. The reflector hood also decreases the stated efficiency of an HPS fixture.
What are high pressure sodium bulbs used for?
High-pressure sodium (HPS) lamps are part of the family of high intensity light bulbs that put out large amounts of light generally needed for street lighting and security lighting. The combination of metals and gasses within inside the glass tube produces an orange-white light commonly found in street lights.
How many lumens is a 70 watt high pressure sodium bulb?
70-watt HPS bulbs provide between 6300 and 7000 lumens of light in frosted and clear options.
Are LED lights safer than HPS?
Switching from antiquated HPS to modern LED lighting can dramatically reduce the risk of accidents, provide a safer working environment and lower the long-term liability costs of exposing workers and consumers to hazardous materials.
Can you leave grow lights on 24 hours a day for tomatoes?
Tomato plants don’t seem to suffer any adverse affects from the 24 hours per day treatment. Keep in mind that 24 hour light will significantly speed up growth which could make a seedling get too large for the pot its in and/or be ready to plant outside well before the weather is agreeable.
How many hours a day do you leave grow lights on seedlings?
In general, seedlings should receive roughly 14 to 16 hours of light a day when situated in a south-facing window. This can be very difficult to achieve, and most growers opt to use artificial lights for their seedlings. These fluorescent lights should be left on for 12 to 16 hours a day.
Will LED headlights melt the housing?
#3: The brightest LED bulbs are proven to create the most heat. #4: Even on the LED bulbs that create the most heat, they are still not hot enough to damage anything in/on/around the headlight housing.
Do high pressure sodium bulbs contain mercury?
All commonly available fluorescent tubes and high-intensity discharge (HID) lamps contain mercury. The most common HID lamps are mercury vapor, metal halide, and high-pressure sodium lamps. Lamps manufactured after 1994 contain less mercury—an average of a little less than 23 milligrams of mercury per 4-foot-long lamp.
