Ideal for professional growers seeking advanced supplemental lighting that drives superior plant quality and vigor. ## Description AgroMax Pure UV is the industry's most advanced supplemental ultraviolet grow lamp, with 15x more power than other types of UV lamps. Supplemental UV-B light can have desirable effects in the phenolic compounds, flavonoid pigments, resins, oils, etc. of many plants. Using advanced phosphors and highly-specialized UV transmitting glass, Pure UV lamps emit a 3:1 ratio of UV-B to UV-A with a slight amount of visible light to produce such sought after effects through a plants own natural processes and without the use of chemicals.Please note: reaction to supplemental UV can vary among plant strains. Applied UV levels will be affected by; 1) number of lamps, 2) distance, and 3) efficiency of the fixture power supply & reflector.WARNING: Overexposure to UV light can be harmful to humans and plants. Proper protective eye-wear and long-sleeve clothing is necessary when working with Pure UV lamps. When supplementing gardens with Pure UV lamps, begin with the lamp placed further away from the plants and run it for shorter periods. Read instructions carefully before use.SIZE & COMPATIBILITY INFORMATION:AgroMax 4' F54T5HO bulbs are compatible with 4' T5HO fixtures only. Please confirm your fixture's compatibility before ordering as fluorescent lights come in numerous sizes, each requiring a specific bulb wattage and size. AgroMax T5HO bulbs follow the industry-standard size coding format (FxxTy), in which F stands for fluorescent – the first number (xx) indicates wattage – T indicates the tubular shape – the second number (y) indicates the tube diameter in eighths of an inch (T5 = 5/8" diameter) – and HO stands for high-output: (F54T5HO). Because T5HO bulbs are a specific size/type, they cannot be used in lights requiring different size/types such as T12, T10, or T8 fixtures. Review: Used in homemade vitamin D lamp - Used in a homemade UV lamp for vitamin D. These are powerful, so be careful with exposure time, and eye protection. It has helped me a lot. Review: Best 75% UVB, 25% UVA lamp available! Don't be fooled by UV lamps w/built-in reflector! Read why! - I just received my AgroMax 4ft Pure UV lamp, as well as a single bulb T5 fixture with an ALUMINUM REFLECTOR. Aluminum reflectors are a "must have" for any UV light. Even the Mylar covered reflectors are useless with UV! Another Very Popular UV lamp, same 75% to 25% ratio, but advertise that they're UV lamps have a built-in reflector, ARE NOT BEING TOTALLY TRUTHFUL! The lamps may have a reflector, but Apogee Meter w/UV/IR showed no difference between other UV lamps with No Reflector vs the built-in reflector brand. That's deceiving! This lamp with an Aluminum reflector should put out over 2X the output over the "built-in reflector brand" that's very misleading! THIS IS THE ONE! ## Features - Fixture Compatibility: For use with all T5HO fixtures requiring 54-watt linear tubes - Size Specifications: Bulb length = 45.75", bulb diameter = .625" (T5) ; Base size = mini bi-pin (G5) ; See below for additional size information - NOTE: AgroMax Pure UV Spectrum - advanced horticultural UV lamp is intended for supplemental lighting use only.
