This lamp is our 275 watt SB Par-38 Narrow Flood Lamp which produces more UVB and UVA than a standard Mega-Ray® 100 & 160 watt lamp, along with more heat, and can therefore be used at greater recommended distances.
This Mega Ray Pet Care Lighting™ original design provides the necessary UVB, UVA and heat for your UVB-dependent basking reptiles.
More UVB - But Safer
Our Mega-Ray® SB 275-watt Narrow-Flood Lamp produces more UVB than other true Mercury Vapor Floods, yet is safer for owners! Our design directs the majority of the UVB from the face of the bulb, rather than diffuse it across a 180° angle.
Longer Useful Life
Using cutting edge technology coupled with five years of dedicated research and testing, we have conquered and significantly reduced the huge decay rates so common in other Mercury Vapor lamps. While other bulbs decay as much as 80%, our newly designed SB bulbs decay less than 30% over the life of the bulb. This is unseen in the industry.
Most people with UVB meters are getting 18+ months use out of our SB bulbs.
Mega-Ray® SB 275-watt narrow-flood is a 275-watt Self Ballasted Par-38 True Frosted Flood Lamp. A true flood lamp, it will disperse usable UVB in a 30" circumference at a 34" distance.
MINIMUM distance setting of 34" will produce approximately 150-200 microwatts per square centimeter (uW/cm2) of UVB and 900-1200uW/cm2 of UVA.
MAXIMUM distance setting of 46" will produce approximately 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.)
This 275-watt self-ballasted bulb also produces heat. It is very important that you monitor the heat at the basking area and adjust the fixture-to-basking area distance accordingly to maintain a proper heat gradient. ALWAYS triple check the temperature at the basking spot - never risk burning your reptile.
This bulb is warranted to produce at least 50 microwatts (uW/cm2) as measured with a Solarmeter™ 6.2 at the minimum recommended distances at the end of its warranty period and our testing shows, on the average, much higher readings. Only ReptileUV Mega-Ray® UV products can make this claim!
