Lumatek Digital Ballast Technical Bulletin

All new Lumatek ballasts feature super lamp compatibility and should work perfectly with any lamp manufactured according to American specifications.

These ballasts are voltage specific and must be operated on correct input voltage 120 or 240 volts Some of the competitors ballasts operate on either 120 or 240 volts however these types of ballasts are unable to offer the efficiency and consistent output of a dedicated voltage ballast.

Lumatek ballasts are now internally RF shielded and can be used with a standard Hydrofarm All-Systems Cord set or lamp cord. Our ballasts produce the least amount of EMI (electro- magnetic interference) of any electronic ballast

The new Lumatek ballast is protected from voltage surges by an external fuse system. This fuse is located under the input cord receptacle. Check this fuse first if the ballast does not function. Replacement fuses are included with the ballast.

DO NOT USE A NEUTRAL- 240V ballast wiring - VERY IMPORTANT! It has come to our attention that customers are using a NEUTRAL wire in their 240V electrical system. All digital ballasts will malfunction if the 240V circuit has a NEUTRAL. The input for the ballast is 2 HOT WIRES and I GROUND WIRE. Some electricians insist on wiring a neutral with their 240V installations. This should not be done when using electronic ballasts. If you are using a light controller ONLY bring a ground wire and two hot leads from your electrical panel. Please call our technical support department at 1-866-369-8943 with any questions regarding this.

Hot Restrike- It is very important that the lamp is given adequate time to cool down before it is reignited (10 min). Hot restrikes cause premature lamp failure and lumen output degradation. Additionally the lamp should never be turned off before the lamp reaches full intensity.

HPS/MH- Lumatek ballasts operate both metal halide and high pressure sodium lamps. They will not light MV mercury vapor lamps which are commonly sold in hardware and some hydroponic stores.

*Please note the 750 watt ballast is HPS only.

Mounting Location- Do not install ballasts in areas of high heat such as an attic or a closed closet. Do not mount the ballast to the reflector or blow exhaust air over them. Do not stack ballast on top of each other. Do not allow contact with water. Mount units at least six inches apart. If a unit has any leaking resin please relocate to a cooler area or place a fan near the ballasts.

Lamp Replacement- Be sure to disconnect the power source before changing lamps. Always use the specified wattage of lamp. (A 400 watt halide lamp should not be used in a 600 watt ballast). Lumatek recommends lamp replacement every 6-12 months.
