Mega Ray 100w mercury vapour E27 – PAR38

This lamp is Mega-Ray’s top-of-the-range 100 watt SB Par-38 Narrow Flood Lamp which has been shown in tests to produce similar amounts of UVB to natural sunlight! – along with adequate heat to create a basking spot at the recommended distances, in many circumstances. Mega-Ray¨ SB 100-watt narrow-flood is a 100-watt SB Par-38 True Frosted Flood Lamp. A true flood lamp, it will disperse usable UVB in a 30″ circumference at a 20″ distance. MINIMUM distance setting of 12″ will produce approximately 150-200 microwatts per square centimeter (uW/cm2) of UVB and 900-1200uW/cm2 of UVA. MAXIMUM distance setting of 20″ will produce 50-75 microwatts per square centimeter (uW/cm2) of UVB. (Distance is measured from lamp face to basking spot or reptile for optimum UVB and heat.) Most people with UVB meters are getting 18+ months use out of our SB bulbs.
