The risk depends on what type of bulb you are dealing with. Compact fluorescent lights contain a small amount of mercury, which can be toxic if it enters your body (see References 1). LED lights have been found to contain arsenic and lead, also at very low but potentially toxic levels (see References 2).

Never look directly into LEDs and wear sunglasses. The bottom line is that LED grow lights are no more dangerous than any other type of grow light. HPS is much more dangerous than LEDs – high heat and risk of burns, risk of broken bulbs and fires, high environmental damage due to mercury content, high carbon footprint.

The study found that exposure to light-emitting diode (LED) lights can cause irreparable harm to the retina of the human eye. Once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow, Think-Spain.com reported.

LEDs have a characteristic delay when turning them on which may be more than you're used to from a lifetime of incandescent bulbs. Swap the LEDs from one position to another, and the problem should move with the bulb. Replace the LED with the equivalent incandescent (temporarily) and it should go away entirely.

Incandescent light bulbs, compact fluorescent light bulbs and LED light bulbs, all produce blue light. But blue light only exists as a small fraction in the wide colour spectrum that natural light gives. Under normal circumstances, the blue light that LED bulbs give off does not cause much harm to our eyes.

Because these lights operate at a very low voltage, they are less inherently dangerous when taken on their own. Some believe the 120 volts generated by an incandescent light can introduce a fatal charge, whereas the power from low-voltage lights, generally 12 volts, can injure but not kill.

The shell is fragile, and if it breaks, it produces thin shards of glass that easily penetrate skin and eye tissues and can even be inhaled. Incandescent bulbs pose a hazard when carelessly thrown in the trash, creating shards that can cut unsuspecting waste facility workers.
