Mega-Ray EURO ZOO SB 160 watt 220volt Self-Ballasted Flood UVB Lamp

Product Code #160HVZ

Mega-Ray® EURO ZOO SB 160 watt Self-Ballasted Flood UVB Lamp - 160 watt 220volt Currently on Back Order
Simply Incredible
for Zoos Across the World!

This is our 220 volt (European line voltage) product. Need a 120 volt (USA line voltage) lamp? Choose our 120 volt Mega-Ray® SB Zoo lamp instead.

This lamp is our top-of-the-range 160 watt Self-ballasted Par-38 Narrow Flood 220-volt (European Higher Line Voltage) ZOO Lamp which has been shown in tests to produce similar amounts of UVB to natural sunlight at the recommended distances.

This Mac Industries/Westron Lighting original design provides the necessary UVB for your UVB-dependent basking reptiles at much greater distances than other brands of reptile lighting, making it ideal for use in very large enclosures in zoos and private collections. This Mac Industries/Westron Lighting original design is found nowhere else in the world!

There is no warranty on European wattage bulbs except to Canada.

This lamp is a quality, very high output UVB source. It will only be sold to zoos, qualified herpetologists or individual hobbyists who own a UVB meter. Most Hobbyists should use our regular Mega-Ray® Flood Lamp range (EB or SB)

The Mega-Ray® European Zoo SB is a 160 watt self- ballasted par38 clear faced 220 volt mercury vapor bulb that will produce useable UVB in a 2 foot circumference at the recommended distances although the highest reading is centered.

MINIMUM distance setting of 3 feet (approx 1 meter) will produce approximately 250-300 microwatts per square centimeter (uW/cm2) of UVB and 2,000uW/cm2 of UVA.

WARNING! Do not set this lamp closer than 3 feet. Reptiles should not be exposed to more UVB than they would be in their natural habitat (350 - 400 uW/cm2 maximum).

MAXIUM distance setting of about 8 feet will produce approximately 20 to 30 W/cm2 of UVB. We recommend two lamps be used if this distance is needed. (Our MegaRay EB kits run more efficiently than the self ballasted bulbs, and therefore different readings may be obtained between the two.)

Please keep in mind that the spectral iridescence of the Zoologist bulb has almost twice the vitamin D3 IU capacity as the natural sun, and therefore will produce great circulating D3 at lower UVB readings. Please read the report at under the heading "Vitamin D3 and LUX meter readings" to get a greater understanding of the subject.

Warning: Very Little Heat

This bulb produces very little heat at a distance of 3 feet. Be sure your reptile is heated properly and if necessary, increase the heat at the basking spot using a good heat source like our Mega-Ray® Heat Projector. ALWAYS triple check the temperature at the basking spot - never risk burning your reptile.

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 EB bulbs.


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!

The product will be replaced with the remaining 6 month purchase time covered. Example: after 3 months use, the product fails. You will receive an item with a remaining 3 months on the warranty.

Not sure if this is the right bulb for you?

Please read our FAQ page. If still confused, email or phone us and let us know:
  1. Your enclosure size & type
  2. Distance from lamp to reptile (or basking area)
  3. Type of reptile
  4. Ambient air temperature in your house.
Phone consultations are the best form.

How Much is Too Much?

Some other new mercury vapor products currently on the market can be deemed dangerous to reptiles, emitting up to 3 times more than the sun does, yet many others emit very little UVB. Basically it comes down to this:

50-250 uW/cm2 mimics the natural environment enough to keep your UV-dependent BASKING reptiles healthy, depending on the species, according to the latest research. At Mac Industries, we choose to be responsible in our approach to high-output UVB-emitting Mercury Vapor lamps. Your reptile's health is just as important to us as the customer service we provide.

So we aim to produce products which provide UVB within these safe limits when our lamps are used properly according to our instructions.
