This is the best air-cooled DE reflector available - period. Other air-cooled DE reflectors allow the air to pass over the lamp or through the lamp compartment. While this does remove more heat, it also has a negative impact on the quality and spectrum of light produced by the lamp. This is due to the fact that DE lamps use quartz instead of borosilicate glass, which offers less insulation to the inner arc tube. DE lamps are designed to operate at a very high temperature. While other air-cooled reflectors cool the lamp and take away from the light, the AC/DE positions the lamp deep into the top of the hood, keeping the lamp at the temperature the lamp was designed to run at.
Reflectors like the ones used in the Gavita and ePapillon are designed for greenhouse use, where they are used to only supplement natural sunlight by increasing the number of hours of light the plants receive. Reflectors like the AC/DE are designed for indoor use, where they are used as the only source of light. Systems like the Gavita utilize very small reflectors which produce a very narrow cone of light. The reason for this is that they are mounted very high above the canopy (usually 8' or more); at this height, the narrow cone is at it's widest so it is able to cover a large area. The other reason for the tiny reflector is that since these lights are only on for a very small number of hours each year, they don't want a big grow room-style reflector blocking all the natural sunlight during long periods of time the lights are turned off.
These greenhouse fixtures also have the ballast attached to the reflector. The reason for this has to do with installation. When you're installing thousands of fixtures in large greenhouse structures you want a compact system that you simply have to hook onto the supporting structure and plug into an outlet box. Having to deal with a remote ballast and lamp cord would add significant time and labor costs and would serve no purpose since it's impossible to locate the ballasts outside these massive structures (there is a limit to how far the ballast can be from the reflector without misfiring the lamp). In a grow room we want the exact opposite. We want the ballast (if possible) to be located outside the grow room because it produces a significant amount of heat that would increase the amount of HVAC equipment necessary to cool the room, as well as increasing the monthly electric bill. This is why most experienced growers choose DE lighting systems that utilize remote ballasts, and reflectors that are designed for the purpose they are actually using them for.
A word of caution, however. The AC/DE produces so much plant usable light that they must be mounted at least 3-5 feet from the top of the canopy, so they should only be used in rooms that have high ceilings. We do not recommend using them in rooms with 8' ceilings, even if the plants will be placed on the floor, unless the plants are not going to get above 2' in height. But if you are in a warehouse with 10' or higher ceilings, then this is the reflector for you. When mounted high above the canopy these reflectors will cover an area approximately 4' wide by at least 5' or more long. Forget all the hype and marketing regarding greenhouse-style lighting systems. If you are a serious or commercial grower, get the equipment that is going to get the job done in the most efficient manner possible.
Made specifically for double ended 1000 watt HPS horticulture lamps (not included). Unique double ended construction allows for maximum optical efficiency and uniformity. Full spectrum DE lamps used in this fixture focus on the red component for increased photosynthetic response. They offer improved PAR values and increased PAR/lumen maintenance (up to 90% PAR at 10,000 hours of operation). The AC/DE’s patent pending design allows removal of heat generated by the lamp without cooling the lamp below proper operating temperature. 95% reflective textured German aluminum interior with 98% reflective "Silver" corner inserts offer excellent uniformity, output and diffusion. Galvanized steel housing with durable powder coated finish. Manufactured with exacting standards and double neoprene gaskets for an air tight seal. Hinged glass makes changing lamp and cleaning glass easy. Detachable 15’ lamp cord at the reflector and at ballast. 5 year warranty.
