Case of 12 T-8 Bulbs.
New for Zoo Med these now contain the highest amounts of both UVB and UVA wavelengths provided by a fluorescent bulb, according to an independent laboratory analysis.
Different than the 5.0 in that the wavelength penetrates a full farther 20-22" from the bulb's surface. Reptisun uses pure quartz glass sleeves. The bulb's UVA/UVB wavelength remains effective for 1 to 1-1/2 years.
Important Shipping Note: Fluorescents and Mercury Vapor bulbs have to ship UPS or other carrier, due to USPS restrictions.
