400W HPS Mogul Base Bulb / Lamps ED18

can this light be screwed into a regular light fixture such as a standard lamp? if not what is the cheapest fixture i can get for it? thanks.

long and short...no you CAN NOT just screw this into a regular light fixturee and woolllaaa' I wish it were that easy, what you reall can not tell from this picture is that the "screw" part of these types of bulbs are over twice the size of a normal incandestant light bulb. This type of light will require a ballast to transform your household current to the current that this type of bulb needs.

HPS Ballast 400 Watts, CWA, Quad Tap

thats what you need. for this light to work, but you also need the fixture, so when it comes fdown to it, your better off buying from a place that can sell it all to you as one package, the light/fixture/ballast. You can probably pick one up for 200 bucks. well atleast you can around here.

Hope this doesnt confuse you anymore

Purchasing

From store:
· Pay in cash, nothing with your name on it (no paper trail)
· Act calm and confident. If you act shady, they might report your license to the authorities.

· Know what you are going to buy before you get there, so you can just walk up and ask for it.

Online:
· Make sure that company sends the packaging in discrete packaging. Nothing with Hydro, Horticultural, or any other growing references. This will help ensure that your package will not be watched. This is also good if you are getting it shipped where people will not know of your operation.
· Always make sure you check out the return policy on damaged and non-operational equipment.


For my example, we will put together a 400w HPS lighting system: (example prices)

· ballast (400w includes igniter and capacitor) $69.29
· porcelain mogul socket $13.20
· bulb (There are many different bulbs, each with different spectrums. This is a cheap bulb) $16.15
· 20' extension cord (length will vary) $8.00
· wire nuts and electrical tape (estimate) $4.00)
TOTAL: $110.44

Accessories. Reflectors are not necessary, but even a cheap batwing style reflector will benefit you by directing the light where you want it. Ballast boxes are also not necessary, but having one reduces the risk of electric shock, burning, and fire.

Optional parts
· reflector(batwing) $30.37
· batwing reflector $21.67
TOTAL: $52.04

Grand total: $162.48 + shipping

The items listed above will give you a fully functional HPS system that is much like one that you can buy.

If that price is too high, the reflector and ballast box are expendable. You can make your own reflector and you can mount the ballast on just about anything that can take screws. Doing so, introduces the risk of you touching the ballast components and getting burned or shocked. As long as caution is exercised, you have nothing to worry about.

Additional Options

Air-cooling is another option that people would like to look into more often. Having separate ventilation for your lights will ultimately benefit you as you will have more head room for your plants to grow and the temperature will be greatly reduced.

There are 2 method of obtaining an air-cooled reflector/hood:

1) You can build your own using:
· This FAQ on how to build an air-cooled hood, with integrated carbon scrubber, and light trap (for the true DIYer)
· This FAQ on how to build a cool tube *recently updated
Note: If you are going to make the cool tube from above, you can hang the cool tube assembly underneath a stationary reflector, which can either be homemade or manufactured.

2) You can buy a complete air cooled hood online, or at hydro stores


Assembly

Now that we have all the parts that we need, we need to wire up the ballast and assemble the light together. I will point you to this FAQ that taught me how to wire my first ballast. http://www.overgrow.com/growfaq/966

Connector plugs

A good way to connect the socket to the ballast is to install a set of connector plugs between the ballast and the socket. This will enable you to disconnect and move the light without having to disturb your wiring. Also, you can locate the ballast in another area as to keep heat down in you grow area.

Take a 10' - 15’ extension cord and cut it into 2 lengths. The shorter one should be the male end (the one with the prongs) and the longer one should be the female (the one with the holes). You will probably want to have the shorter one be around one foot long. It is the piece that is going to be connected to the socket/bulb assembly. The longer piece will need to be long enough that it can reach the other piece of cord from wherever you are going to place the ballast.

Note: We attach the ballast to the female side in order to reduce danger of electric shock. In a rush to pull apart the set up, a person might leave the ballast on and accidentally touch the prongs on the wire. Trust me; you don't want to get shocked by a ballast of any wattage.

Connect the white wire from the male end of the extension cord to the white wire of the socket. Connect the black wire of the extension cord to the black wire of the socket. Connect the green wire, if you bought a socket that has a grounding terminal.

You will want to connect the female plug to the ballast. Connect the white or COM wire that is coming out of the igniter to the white wire of the extension cord. Connect the black wire from the extension cord to the RED or X2 wire coming from the igniter. You can also connect the green (ground) wire to the same place that you grounded your ballast.

Additional Information

LIGHT SAFETY

· Remember not to spray water on or near an exposed HPS light bulb, especially when its on (foliar feeding may cause the bulb to explode if water touches the bulb)!
· Do not look directly into the HPS for any amount of time. If you are going to be in your grow room for a long amount of time, wear sunglasses
· Do not touch an HPS bulb while it is hot · Do not touch an HPS ballast while it is hot
· Replace your lights every 10000 to 15000 hours

aside from the advice you've gotten here, the page you posted has a link to "MH and HPS Grow lights" down below. I didn't look at the prices, but they've got the stuff you need.

hey mogie you still around? my buddy plugged a ballast into the wall at 240v and into the ballast at 120v and it blew it. do you know what part would have blown? I have a ballast, ing, cap, should i replace all? also the lamp adaptar at the ballast is fried do you know where i can get this part?
