new lights

Discussion in 'Growing Marijuana Indoors' started by Just Smoke It, Apr 1, 2013.

  1. Hey everyone Im about to buy a couple sets of lights off a friend for 50$ a piece they are 400 watt ballast and have been owned for 2 years. Im not sure if this is a good deal or not because I dont know much about lights. Anyways each setup comes with a 400 watt hps ballast, a wing reflector, the cords ( which seem to be wired to each other), and a bulb.

  2. Good deal It works right

  3. well, it is a commercial ballast (used in building or parking lot lighting)

    It's all about how much light is left on the bulb

    AND keep in mind a $120 digital light will do MH and a HPS bulbs
    (with one ballast, you just change bulbs)

    (You should use an HPS to do the budding)

    Do you have a plan for that?

    Hope This helps
     
  4. Cool, but yea I plan on vegging with my metal halide or cfl, Ive read that you can use mh bulbs in an hps but not vice versa. However if that doesn't work I dont mind investing in mh conversion bulbs. Btw I have already had one grow but I didnt have my own HID lights so I used a friends room for flowering and vegged with cfls.
     
  5. The bulbs should get replaced every 6 months to year. Over time the bulbs light decreases and yields will suffer.
     
  6. Alright Ill ask how long hes been using the bulbs, would 1000 watt bulbs work in it because I have a couple. Or do they need to be 400 watt bulbs.
     
  7. Yes you can just not the other way around 400 in a 1000

  8. Sounds like a good plan

    This is SO TRUE !! the thing is it will still use the same amount of electric
    You can get a light meter to tell if the bulb is still putting out enough light

    Skimping or your bulb will drastically reduce your yield ....

    Come on man, you MUST use the bulb size the ballast is rated at......
    If not, you WILL smoke the ballast, you could have a fire, or burn out the bulb

    Later :wave::wave::wave:
     
  9. A 400 watt ballist is only going to put out 400 watts it has no idea that the bulb in it is rated at 1000

    I agree get the right size but it can be done

    Im definetly gonna get new bulbs if needed, I was just curious if it was possible.

    When I set up these lights I was thinking about hanging them vertically one on each side of my room instead of hanging them above my plants. I Think it will help the plants bottom halfs in producing like the top half.
     
  11. What is the size of the room and how many plants are you going to grow ?

    4'(d)x4'(w)x8'-10-(h) my ceiling is slanted and I plan on growing 5-6 plants.

    I just picked up the setups today, they work and are in good condition. However hes been using his bulbs for about 2 years so I definitely am going to get some new bulbs. I need to start off by getting some metal halide conversion bulbs though so I can veg, Im not really sure on how the conversion stuff works all I know is that hps need ignitors and mh don't but I've been looking at this bulb http://www.ebay.com/itm/Plantmax-MH...256?pt=LH_DefaultDomain_0&hash=item2ec4d6f870 , is there a way to know for sure if these will work in my fixture?
     
  13. Well, I thought it was a MH ballast?

    If it is a MH ballast, you just need a regular MH bulb

    Anyone want to weigh in on this with me??

  14. Nope its an HPS ballast and I have 2 HPS bulbs but they're two years old. I got all my old equipment out of my room today and set up the lights. Now all I need is my new bulbs and I'll be ready to go. I've read multiple threads that say that you can use a MH bulb in an HPS but not vice versa but then I read ones that say otherwise. So I have decided to just play it safe and get a Metal Halide Conversion Bulb and I did'nt know if I needed a certain type of MH Conversion Bulb or if they are "one size fits all".
     
  15. Sounds like a good plan, any 400 watt MH Conversion Bulb should work

    Don't use a 2 year old HPS bulb to do your buddin....!!!
    (that may be part of why the guy is selling, so he can upgrade)

    I would go with a GOOD name brand bulb like Ushio or HiLux
    (for $40 Ushio has a VERY Good Rep)

    This company has done very well for me and is always cheaper, they are in Ohio if you are midwest or east coast
    (if you look at my build in my sig you will see the money I have spent with them)

    Ushio 400W 5200K Universal Metal Halide Conversion Bulb - Plantlighting Hydroponics

    OR if you have the money

    HiLux 400W Enhanced Spectrum Metal Halide Grow Bulb - Plantlighting Hydroponics

    Keep us posted !! Good Luck !!!

  16. Yea he said he was upgrading to a single 1000 watt fixture. I took a look at the Ushio bulbs and I was gonna purchase but it says my fixture must have a glass lens, how would I know if it does or not? Also when he showed them too me they both worked fine but when I did one ballast wasnt lighting the bulb then I switched bulbs and both fixtures worked does that mean theres something wrong with my ballast?
     
  17. Are you saying he has two lights wired to one ballast ?
     
  18. Nope, I have two complete 400 watt setups. However when I plugged them both in one lit up one didnt. So I switched the bulbs to see if the bulbs were the problem. When I switched the bulbs both started working and I was just curious if that means one of my ballast could be malfunctioning.

    My other question was about the ushio bulbs you linked, Im interested in them but they say the bulb requires my fixture to have a glass lens and I dont know how to check if mine does or not.
     
  19. In the bottom of the bulb socket (the part you screw the bulb into) there is a metal contact that matches up to the metal "dot" on the bottom of the bulb

    Sometimes the metal contact gets pushed to the bottom of the socket too far (like flattened out too much) with the unit unplugged use something plastic to lift it up just a very small bit (like 1/8 an inch max)

    CAUTION: even with the unit unplugged there may be a capacitor in the ballast that still has a charge stored THAT CAN SHOCK YOU


    Use caution because if you bend it up a lot, abruptly I have seen them just break off

    Then the next time you screw a bulb in don't over tighten it.... Make it tight but try not to "crush" the contact

    About the "glass lens" They mean a glass lens on your hood, you don't have one and many people don't, I believe they are just warning you about the danger of getting liquid MIST on the bulb WHEN IT IS ON..... (it will pop if you do) or if you touch the bulb, or fire risk by contacting the bulb

    NEVER MIST (Spray liquid) with the HID on....

    If you look at my build in my sig you will see I got the plate glass sealed hoods for the unheard of price of $99, all of those reasons are why
    (and better heat control)

    You better understand what you are getting into, there is always safety & fire risk

    Here is the manufacturers website

    HiLux Gro - Grow Light - Horticulture - USHIO

    Download the PDF and read it and Click on the 3rd blue tab "Super MH"

    "WARNING: This lamp can cause serious skin burn and eye inflammation from shortwave ultraviolet radiation if outer envelope of the lamp is broken or punctured.

    Hope this helps....
