Read Answers for Lumatek 600W Digital Ballast HPS/MH 120V/240V Dimmable & Multi-Watt

Waht is the difference between a "common" & "hydrofarm" plug type. -Tom Hamilton

The Common Plug and Hydrofarm Plug are two different plug styles for connecting your ballast to your hood/reflector. We have a compatibility chart here so that you can match up ballasts with hoods/reflectors and vice versa: -Greners Staff

Does the Lumatek 600W include internal sheilding to prevent the ballast(s) from causing prolems with my and my neighbors TVs, Radio, etc? Thanks. -Richard Myers

The Lumatek ballast comes with an attached 15ft. RF shielded output cord. Digital ballasts which do not employ shielded cords can seriously disrupt radio and satellite TV signals for up to 50 yards, as well as pH equipment. The Lumatek ballast, if properly connected, will have minimal RF interference at less than 5 ft. and will not interfere with pH equipment. In order to ensure maximum RF shielding, the output cord must be wired directly to the socket. If the ballast is connected to an existing unshielded wire, it will cause radio and satellite television interference. Both ground wires should be grounded to the socket set for maximum RF interference suppression. If it is necessary to extend the output cord further than the 15ft. supplied, the customer should purchase RF shielded wire to lengthen the output cord. -Greners Staff

Can I use a 600 HPS bulb and run it at the 400 Watt dimmable setting or would I need to use a 400 Watt HPS bulb? -Archie Cruz

You can run a 600w bulb on a 400w setting, but it is recommended that you turn off your ballast and let it sit for at least 5 minutes before you turn your ballast back on in the lower setting. There have been claims that running a bulb on lower wattage decreases the life of your bulb, but we have not seen any data to support this, though we also don't doubt that this may be the case. -Greners Staff

What is the difference in the dimmablility feature between the lumatek and the phantom? -matthew.w

The Lumatek 600w dims down to 400w or 300w, while the Phantom dims down to 75% (450w) or 60% (360w). -Greners Staff

Since they dont make 600w metal halide bulbs, can I use a 400 watt metal halide bulb on the 400w setting? if not what would be the best HPS bulb for veg. -Hank

They do make 600w bulbs in the veg spectrum, they are known as conversion bulbs. Using a 400w bulb would work just fine as well if wanted to use a bulb with an enhanced blue spectrum. You veg your plants under any HPS light, but they will not grow as healthy or bushy. EYE Hortilux Super HPS does have a relatively high spectral energy in the blue spectrum. -Greners Staff

Will the 8ft, 120V power cord work with this ballast? It says it is notched, does that matter? -Tyler Williams

Yes, all standard 120v and 240v cords will work with this ballast. -Greners Staff

I had a question pertaining to this particular Lumatek 600w ballast, exactly how many watts is used to power up this ballast? If 600w's then I assume a 250Watt Phantom Ballast runs at 250Watts also? Sorry I'm just trying to be energy efficient and figure out the total costs. -Kats

As a general rule, most digital ballasts run at 5-8% over their wattage ratings due to regular inefficiencies in the system. A 600w ballast will typically draw 620-640w while a 250w ballast will draw 260-275 watts. This can vary based on different variations in set up, length of wire runs, types of bulbs used, etc. -Greners Staff

How many amps does this model consume? -JC

The Lumatek 600w digital ballast draws 5.47 amps at 120v and 2.74 amps at 240v. -Greners Staff

Does the 600 watt Lumatek ballast use 600watts when it has a 400 watt bulb in it with it switched on 400 watt output setting?? In other words does it draw the same amount of power either way? or does it actually adjust amount of power draw for each setting??...also do you carry the latest models of Lumatek ballasts? -Jordan

While we have not tested this with the 600w dimmable lumatek,we did the test with a 1000w dimmable lumatek ballast and found that at 1000w, the lumatek drew 1050w after 15 minutes on a super HPS lamp, and drew 670w at the 600w setting with a super HPS lamp. Assuming a 10% loss at 400w, I would expect it to draw 440w when dimmed and between 620-660 w at 600w. -Greners Staff

where can I see the compatibility chart referred to in the answer to the difference between a common and hydrofarm plug type. -Linda -Greners Staff

Right now I have one 1000 watt set up now. Im looking to but 4 of the Lumatek 600 watt digital ballasts that are Dimmable. Can I run my 1000 watt bulbs that I have now with this ballasts If you can run a 1000 watt one and turn it down to 600 watt I would thank it would be OK ?? And if it is OK I would think some of the older 1000 watt bulbs you use for 2 grows or so and then you don't want to use anymore as they lose some of the lumens that they would still be ok to run in the 600 watt ?? what do you think there is a lot of used 1000 watt bulbs out there Tom -Tom

Hey Tom, yes it is possible to use a 1000w bulb on a 600w ballast (if it's and HPS bulb) an MH bulb however will not work the light will flicker on and off for roughly a minute and then its lights out. on the other spectrum of things it is extremely unsafe to use a lower wattage bulb ( a 600w in a 1000w ballast) this can cause extreme over heating, and or envelope failure, resulting in damage and possible injury -Greners Staff

Lumatek 600W Digital Ballast HPS/MH 120V/240V Dimmable & Multi-Watt


Product Information

The market's most popular and best digital ballast. The Lumatek eballast is a performance leader.

  • Dimmable. Allows light brightness to be turned down, or turned up to the Super Lumens setting.
  • Multi-Wattage (read instructions before use). Ballast powers a 600 watt, 400 watt, or 360 watt bulbs.
  • Operate both metal halide (MH) and high pressure sodium (HPS) lamps. No changes are required.
  • Up to 20% MORE LUMENS; faster growth, bigger harvests.
  • Unique graduated fin design for more efficient cooling. No cooling fan necessary means fewer moving parts.
  • 3 years full + 2 years no hassle warranty.
  • Internal resin coating protects components for a long life.
  • External breaker system protects against power surges.

More Lumen Output - Up to 20% more lumens output than some old style magnetic ballasts ...More light equals more yield. We urge you to test this yourself with a good quality light meter. Be sure to also check how much power the ballast is using with an ammeter as many so called 600w magnetic ballasts now draw up to 750w as standard to try to keep up with Lumatek’s lumen output.

Stable Light Output - Excellent for Pharmaceutical-agriculture, laboratories and other uses where precise regularized output is essential.

Fast Start-up - It reaches full brightness in under one minute; magnetic ballasts typically take about twenty minutes.

Completely Silent - No noise or vibration of any kind

Produce Less Heat - Less heat generated by the ballasts allows cooler running of the environment. Less heat is less wasted electricity.

Longer Bulb Life - Lumen output loss over time, with the correct lamp, is dramatically less than with magnetic ballasts.

Usage Notes

Mounting Location - Do not install ballasts in areas of very 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. 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.

Hot Re-strike - It is VERY important that the lamp is given adequate time to cool down before it is reignited. You should allow a hot lamp to cool for 20-30 minutes before you try to re-strike it. Hot re-strikes cause premature lamp failure and lumen output degradation. Additionally, the lamp should never be turned off before the lamp reaches full intensity.
