HID vs HPS

so one of my buddies got a 1000w HID light on his hands and i was wondering whether or not theres a big difference between using the two. Ive read that the HID lights are the white/blue end of the spectrum and make the plants bushier but dont really let the plants grow upwards? i want to put this light in my closet if it will work, but the upward half of the closet (bottom is veg) is about 5-6 feet. will this light work?

metal halide and high pressure sodium lights are both HID high intensity lights

metal halide is for veg/grow
high pressure sodium is for bud/bloom

hope that helps

HPS is HID. . . HID is High Intensity Discharge. HPS is the bulb, High Pressure Sodium is an HID bulb and so is Metal Halide. Metal Halide are the blue HID's and HPS are the red HID's.

You'll need a cool tube if you're going to run it in your closet, they get really hot. I have a 400 watt in my closet and it needs a tube before I can start. I ran it for like 3 minutes to make sure everything was hooked up and it put out so much heat I had to wait 5 minutes before I could put the bulb back in the box, it was so hot I had to use a rag to take it out of the socket or it would have burnt my hands. If you notice the socket for the bulb is made out of ceramic, because the bulb gets that hot!

You should never touch a bulb with your bare hands anyway... the oils in your skin can cause heat spots on the glass causing them to break.

lol, alright well im not sure if its a metal halide or hps light either :P heres some pics though. my buddy told me told me that ide prbly have to take off the casing to otherwise itd just heat up way to fast.

think instead of using a cooling tube i could just throw a vent into my door and then have a fan inside the room?

so would this kind of light only work for veg? and not for flowering. cause i already have a bunch of T5's for veg, was hopin i could use this for the upstairs :P

I don't think you understand how hot they get, plug it in and stand next to it. You're going to need to get the hot air out and keep it away from the plants, a cool tube is the best way to do it. They do have some DIY cool tubes on here just do a search.

yea...its actually 347V....i dont know much about electrics but im guessing thats way to much? i was going to have a buddy of mine come check it out cause hes an electricion but do u think the estup is doable with this light at all? would a DIY cool tube work?

I think 347V is 3 phase, which means you're going to need a different grid then your standard home box, unless your buddy can hook you up with an inverter. It just doesn't seem practical now, unless it's a multi input ballast and you just don't know it yet. Are you in the USA or a different country? I tried to get 3 phase for a few machines I own but had to convert them to single phase because the power on my block isn't industrial, you might have the same problem.

It may not acutally be 3 phase but 347V is nothing to mess with unless you know what your doing. I just read an acticle about a 19 year old boy who was killed by 347 because he thought he was working with standard 110v. This goes for 220v too, you really shouldn't mess with it unless you know what your doing because it will kill you.

"The neutral point of a three phase system exists at the mathematical center of an equilateral triangle formed by the phase points, and the line-to-line voltage of a three-phase system is correspondingly times the line to neutral voltage. Where the line-to-neutral voltage is a standard utilization voltage (for example in a 240 V/415 V system), individual single-phase utility customers or loads may each be connected to a different phase of the supply. Where the line-to-neutral voltage is not a common utilization voltage, for example in a 347/600 V system, single-phase loads must be supplied by individual step-down transformers. In multiple-unit residential buildings in North America, lighting and convenience outlets can be connected line-to-neutral to give the 120 V distribution voltage (115V utilization voltage), and high-power loads such as cooking equipment, space heating, water heaters, or air conditioning can be connected across two phases to give 208 V. This practice is common enough that 208 V single-phase equipment is readily available in North America. Attempts to use the more common 120/240 V equipment intended for three-wire single-phase distribution may result in poor performance since 240 V heating equipment will only produce 75% of its rating when operated at 208 V." http://en.wikipedia.org/wiki/Three-phase_electric_power
