Frequently Asked Questions

1. Does the Glass included with my reflector block UV and/or Heat?

Yes and Yes. All glass has naturally occurring UV inhibitors but we are not adding additional filtration as some amount of UV is known to be beneficial, the primary function of the glass lens is to aid in heat retention and evacuation (air cooled).

2.How much light am I losing by having the glass lens in this fixture?

Clear glass does result in slightly reduced light due to the lambertian refraction effect. The amount depends on the lamp type, glass thickness, shape of reflector and reflective materials.

3.Do I have to air cool my reflector?

No, all ETL listed reflectors are tested without air flow being present. However the primary function of an air cooled is to induce air flow and evacuate the heated ambient air.

4.What is the maximum length I can have between the ballast and reflector?

This primarily depends upon the ballast type (magnetic vs electronic) and also the lamp type (HPS vs Probe Start MH). Some magnetic ballasts can use “long range ignitors” for up to 50’, and most Electronic ballasts reliably fire lamp at lengths above 50’.

5.How many BTU’s Does my system and reflectors create?

1 watt = 3.41 btu per hour.

1000watt = 3,412 btu per hour

6.What is the advantage of running my ballast on 240V?

Higher voltage operation reduced the amperage consumption. However we all pay for electricity by the Watt. There is no effective power savings in operating 240v vs 120v.
