Preventing PKC (Photokeratitis) in Reptiles
Photokeratitis (PKC) is a serious eye condition in reptiles, often caused by improperly positioned or low-quality lighting. Lights positioned too close can cause glare, irritating the eyes and potentially leading to infection or burns. Always maintain a safe distance, ideally 12 inches or more.

Poor quality, unregulated lamps, especially inexpensive ones from online marketplaces, are a major culprit. These can emit harmful UVC wavelengths, directly damaging the reptile's eyes. Invest in high-quality, reputable lighting to safeguard your pet's vision.

Visual Lighting: LEDs for Day/Night Cycle
LEDs are popular for illuminating reptile enclosures, helping establish a natural day-night cycle crucial for reptile health and plant growth. Look for full-spectrum LEDs (4500-6500 Kelvin) that are terrestrially visible.

Avoid LEDs with blue and red chips, as these older technologies aren't as effective for plant growth and can give the enclosure an unnatural purple hue. Brands like XO Tara, Arcadia Jungle Dawn are good choices, with the latter specifically beneficial for live plants in the terrarium.

Heat Sources: Ceramic Heaters and Heat Projectors
Ceramic heaters have long been used in reptile keeping. While effective at heating the air, they primarily emit infrared (IR) radiation, not directly usable energy for reptiles. Heat mats only heat one wall, often inefficient.

The Arcadia Heat Projector is a newer option that emits both IRA and IRB, delivering bioavailable energy for the reptile. IRB penetrates deeper into the dermis, providing usable energy. It also produces minimal light (<4 Lux), suitable for 24/7 use.

Visual Light and Heat Sources: Red Lights and Daytime Basking Lamps
Infrared (IR) red lights are often used, but they aren't just heat; they also produce visible red light. While some reptiles might not see the color red, they perceive the light. Red lights are frequently misused, disrupting day/night cycles and potentially irritating eyes.

Daylight basking lamps combine heat and light, but often have shorter lifespans and are less energy-efficient than halogens. Halogen lamps offer a balanced and robust heat and light output.

UVB Lighting: Tubes and Compact Lamps
UVB lighting is crucial for reptile health, aiding in calcium absorption. T5 and T8 tube lights are common, with T5 offering more light per watt. Match the UVB percentage to the species' needs and the distance from the lamp.

Compact lamps can be effective if properly designed and reflected, but spiral or curly designs are inefficient and less desirable. For leopard geckos, a 2-5% UVB tube light is generally suitable in shallow enclosures.

Conclusion and Recommendations
UVB tube lights are effective for leopard geckos, LEDs excel for plant growth and day/night cycles, and ceramic heaters work well with a thermostat to control temperature. The Arcadia Heat Projector is a promising new technology.

Consider the specific needs of your reptile species when selecting lighting. Always prioritize high-quality, safe products to ensure your reptile's health and well-being.
