anyone have a digital ballast? i'm thinking about buying one on an ebay store, its a 400w switchable MH/HPS for like $200 bucks. supposedly they work cooler and more efficiently.

later. :smokin:
 
I saw the same thing on ebay. I don't know what it is. Could just be something to make it sound better. I'm gonna stick to actual stores.
 
Digital? Please explain. What does it have digital tempeture gauges and controls?
 
Also may wanna deeply research that before purchasing... There are quite a few accounts of "digital ballasts" for sale that arent truly digital in control and operation.
 
Is it a digital timer built in? What do you mean by "digital"?
 
here is the description i found for one on ebay for $200

Brightest Ballast on the Market

The Lumatek Ballast is the brightest 400 and 600-watt ballast in the industry. Light meter readings indicate the Lumatek ballast is up to 27% brighter than common core and coil magnetic ballasts on the market. The Lumatek is 10% to 15% brighter than the other electronic ballasts out there.

Over time core and coil ballasts degrade, become louder, use more electricity and produce more heat while the lumen output declines. Digital ballasts do not degrade and maintain lumen output and efficiency over the life of the Lumatek ballast. Magnetic ballasts output can fluctuate by up to 10% during a 12-hour cycle. Lumatek ballasts will give you a constant output without any fluctuation.

Magnetic ballasts can use up to 75 watts (hence 675 input watts) converting the electricity while the Lumatek is sending the FULL 600 watts to the bulb lighting it to its fullest potential. Lumatek ballast achieve superior light meter readings in comparison to other digital ballasts on the market by using microprocessors to detect the precise type of lamp being run and supply the correct power necessary. The microprocessors are "chips" inside each Lumatek ballast. Some lamps are able to use slightly more than 600 watts. The Lumatek ballast will detect this and increase output accordingly.

Electronic Ballast vs. E-Ballast

The Lumatek ballast is an E-ballast unlike brand other electronic ballasts. What is the difference? E-ballasts use a micro processor similar to a personal computer which runs a software program. This microprocessor allows the E-ballast to run both halide or sodium lamps, switch between 50 and 60 hertz, make adjustments for the type of bulb it is running and, will even compensate for degrading lamps by increasing output. The other Electronic ballasts on the market have a constant output and cannot make adjustments or changes. They will light a MH lamp but quickly degrade it.

Lumatek ballasts are programmed to allow for a soft-start and do not require an initial power surge to light the ballast. This increases the lamp life and allows end users to start multiple ballasts simultaneously without a (breaker tripping) power surge. Lumatek ballast will also detect a short in the wiring or a defective lamp; it simply shuts itself off letting the user know something is wrong with the wiring or the bulb is defective. This should be kept in mind if you have a ballast that keeps shutting off. In most cases there is a problem with the output wiring (from the ballast to the lamp).


Can Lumatek Ballasts run both 400 and 600-watt lamps?

Lumatek ballast is lamp specific and only operates corresponding lamp wattage, of either 400 or 600 watts.


Why are there separate ballasts for 120v or 240v?

Lumatek ballasts are voltage specific and cannot be modified to change the input voltage. The 240v digital ballast is more efficient producing light while generating less heat than the 120v counterpart. Other electronic ballasts or dual input voltage digital ballasts are never able to achieve the same efficiency as a Lumatek dedicated 240v e-ballast.

Surface Temperatures

The Lumatek 600w 240v unit can be expected to reach temperatures of up to 107 degrees while the 600w 120v version can reach temperatures of up to 120 degrees within 8 hours of operation. Do not be fooled by inferior units that use fans. Fans do not make the ballast run cooler; they simply remove the heat and increase the temperature of growing area, if the ballast is in the growing area.

RF Shielded Output Cord

The Lumatek ballast comes with an attached 15 ft. RF shielded output cord. Other brands of digital ballasts are not using shielded cords and will disrupt radio and satellite signals for up to 50 yards (including the neighbors). They will totally knock out reception. The same interference was also experienced with pH equipment, and actually changed calibration to incorrect readings. The Lumatek ballast when properly grounded will have minimal Radio Frequency interference (RFI) (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 into the socket. If the ballast is connected to an existing non-shielded wire it will cause radio and satellite television interference. Both of the ground wires (green) should be grounded to the socket for maximum RFI suppression. If it is necessary to extend the output cord further than the 15ft supplied the customer should purchase RFI shielded wire to lengthen the output cord.

Warranty Information

Lumatek offers the best warranty in the industry: 3-year replacement and 2 year prorated, for a total of five years. Lumatek will replace any defective units with brand new units for 3 years from the date of purchase. These units should not be modified or physically damaged. During the 4th and 5th year Lumatek will supply the customer a pro-rated replacement ballast, at $95 for year 4 and $135 for year 5. All warranty issues will be handled directly through the Hydroponic Gardening store where you purchased your Lumatek.

Warranty Information

Do not attempt to open a Lumatek ballast. This will void the warranty. If you were to open up the ballast you would find that all components are encased in epoxy, so there is nothing you can change without special electronic equipment. The return rate is less than 1% and service done by Lumatek's distributor would include checking the microprocessors and re-programming if necessary.

Digital Ballast Market Confusion

There are several look-a-likes to the Lumatek in the market. Please do not assume that these have the same quantity and perform as well as the Lumatek Digital E-ballast. They typically use inferior components and technology and are not true E- ballasts.
 
Yah Digital ballasts are everywhere basically that they sell lights...I think they use circuits instead of a magnet to produce the power or something?? They also supposed to be more efficient and cooler reliable blah blah blah, but more money. I also think all of them, or most, are switchable between MH/HPS - but a switchable MH/HPS old fashion style is cheaper.
 
they call them digital but its really just circuitry rather than the capacitors and coil. i got this from a reputable ebay grow store. they have a couple locations in a nearby town, if i'm up there i'll see whats up with them.

i like the part about the 20,000hz! :cheesygrinsmiley:

Project X Digital Ballasts represent the greatest technological advancement in the indoor-gardening world to date. For over 30 years, maintaining and replacing “core and coil” ballasts, igniters, and capacitors has been the accepted norm. A solution has finally arrived that will make continual ballast repair history.

Outdated “core and coil” ballasts are heavy, hot, and inefficient. Project X electronic ballasts operate at much higher frequencies which eliminate light flutters and constant changes in brightness and color. This higher frequency (20,000hz vs. 60hz) makes exciting internal gasses in the bulb much more efficient and consistent, resulting in longer life bulbs and higher emission levels.

Gone are the days of spiking inherent to traditional ballasts which cause lumen degradation and shorter bulb lives. Laboratory test results have shown that 600 Watt Project X electronic ballasts perform to levels only 5% less than traditional 1000 watt "core and coil" ballasts!!

The stamped reflector creates a highly efficient, uniformly diffused light pattern. Light intensity will decrease with an increase in distance from the light source. It is because of this law of physics that a smaller reflector will reflect more light than a larger one (less distance between the light source and reflective surface). Project X Reflector Systems are the best and most cost efficient available to the hobby grower while still maintaining the utmost quality.
  • Project X digital ballasts run both Metal Halide (MH) and High Pressure Sodium (HPS) bulbs at maximum efficiency and light output.
  • Project X digital ballasts feature a 8 foot power cord and 15 foot RF shielded "detachable" lamp cord which can be extended up to 30 feet.
  • Project X digital ballasts maintain their efficiency throughout their lifespan. Alternatively, "core and coil" ballasts become louder, emit less light, and give off more heat as they age.
  • Project X digital ballasts are factory tested for several hours prior to ship-out. The failure rate of Project X is about 3 in 1000!
  • Project X digital ballasts do not require an internal fan due to the epoxy filled ballast chamber. This epoxy acts as a heat sink and allows for gentle dispersion of heat. Fans are always the weakest link in our competitor’s ballasts.
  • Project X digital ballasts can withstand environments up to 140 degrees.
  • Project X digital ballasts boast the industry’s best warranty of 5 years. First three years is no hassle exchange and two years pro-rated afterwards.
  • Project X digital ballasts are almost 10% brighter than currently offered electronic & digital ballasts.
  • Project X digital ballasts are indestructible. The Project X digital ballasts are completely sealed from the environment (most high output fluorescents are) and can withstand absolute torture.
