All electrical ballasts can fire MH bulbs yet only Switchable or HPS ballasts can fire HPS bulbs--unless you get a conversion bulb. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.

Im wondering if using a MH bulb on a HPS ballast would have the same effect.
Can i use metal halide bulb in hps ballast. A HPS bulb will NOT fire in a MH ballast-HPS bulbs use an igniter to light whereas MH bulbs dont. HPS bulbs wont fire in an MH ballast because it has no ignoter. You can run metal halide bulbs in hps but not hps in metal halide.
With a MH ballast. How do you ignite a 400w electronic metal. Well if you have tested the high voltage of your ballast and it is functioning correctly then you should examine the low voltages of your ballasts.
HPS has more red spectrum which flowering plants thrive on. They have to be same wattage. Moreover they are also much cheaper to run and more versatile too.
HPS ballasts are built with the igniter MH ballasts are not. Work with HPS ballasts. As long as the ballast is operable the 400 watt lamp is almost perfectly sized for the 490 watt max of the ballast.
If both still appears to function properly you should check the wire. Metal halide MH ballasts are required to start the lamp regulate the lamp starting and lamp operating currents and provide appropriate sustaining supply voltage. Does Anyone out there know if you can use a Metal Halide bulb in a High Pressure Sodium fixture.
The MH has more light in the blue spectrumwhich vegging plants like. All electrical ballasts can fire MH bulbs yet only Switchable or HPS ballasts can fire HPS bulbs--unless you get a conversion bulb. Since they do not have a filament to resist.
This is known as color shift a natural effect of Metal Halide over long periods of operation. Signs that a Metal Halide light bulb or ballast needs replaced. While you are removing the bulb you should know the bulb is extremely fragile so place them where they wouldnt get broken.
And just to make things more confusingcheck out CMH ceramic metal halide bulbs. Next remove the bulb from the tombstones that hold it at each end. Let me clarify you can run a MH bulb in an HPS ballast same wattage of course But not the other way around.
In MH lamps ballasts provide the starting voltage and ignition pulses pulse-start lamps necessary to ignite the lamp. All of these require lighting ballasts. Efficient at a real MH lamp working.
A word about conversion bulbsThese are only used to run an HPS tube on a Mercury type ballast. Most would agree that HPS grow lights are better than MH lights in more or less every way imaginable. I have a few unused horticulture pendants that run a 150w HPS bulb.
I have talked to people that have modified their hps ballast by adding a switch to turn onoff the ignitor circuit used by hps bulbs but i. A little spendybut people rave about them. All you need to do is change the bulb Sent from my iPhone using Grasscity Forum.
All those types of ballasts can be used with high intensity discharge HID bulbs which include metal halide MH and high pressure sodium hps. A HPS bulb will NOT fire in a MH ballast-HPS bulbs use an igniter to light whereas MH bulbs dont. I know that most HPS bulbs can be fired on a metal halide ballast it just hums and is bad for bulb life.
-Metal Halide MH High Pressure Sodium HPS Lamps-2 power cords included-Soft Start Technology-Powers 1000w 600w 400w lamps-Constant Power Factor 999 - 892 AMPS 120v 446 AMPS 240 So it is safe to say that both Lumatek and Solis-Tek dimmable ballasts can run different wattage lamps. Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. Usually the lamps will gain a pinkish.
Probe-start MH ballasts however can. Sodium conversion bulbs are designed to be used. Ie- 250 halide in 250 watt hps ballast.
Other than the cost conversion bulbs perform well. Remember the rating on the ballast is the MAX wattage and I have never seen a 490 watt rated lamp. The lamp appears to be a different color or are turning pink.
See What are warm-up and restrike times for metal halide lamps Starting the lamp. A magnetic ballast in series with an AC current voltage source supplies the lamp with a near-constant stream of currentSodium ballast lamps are widely used in streetlights and security lighting as well as applications requiring high color rendering. If you are getting a digital ballastjust ensure it can handle both types of bulbs.
My old church was. HPS bulbs wont fire in an MH ballast because it has no ignoter. HPS Ballast with Metal Halide Bulb.
High pressure sodium ballast output voltage use high pressures of sodium in an excited state to generate light. Like a metal halide conversion that can be used with an HPS ballast. HPS ballasts are built with the igniter MH ballasts are not.
These bulbs cannot be interchanged without changing their ballast the regulating element in all light bulbs. Ive been useing only hps. Unless you have convertable ballast you cant put metal halide in hps ballast.
Yes you can use metal halide lights if you want but generally speaking high pressure sodium grow lights are way better for the flowering stage and produce much bigger yields. A Conversion bulb offers you the opportunity to switch the bulb in your Halide or Sodium fixture without changing ballasts. What is a metal halide conversion bulb.
Let me clarify you can run a MH bulb in an HPS ballast same wattage of course But not the other way around. Take a 400W Halide for instancethe conversion bulb for this ballast is 360W Sodium HPSThere is no such thing as a conversion bulb even though they love to label these things as such for an MH that is to run on an HPS ballastIt is simply that the MH tube has been designed to run on HPS. Usually pretty expensive and are not as.
If you have hps bulb just use it you will get great results. There are some specific MH lamps made to. Do high pressure sodium bulbs need a ballast.
This leaves us with gas discharge lamps including fluorescent metal halide high pressure sodium low pressure sodium and mercury vapor lamps.
