1000 watt HPS

[woodsman]

I did a search on google for 50000 lumens. A bunch of hydroponic systems came up from various websites. For about 400.00 to 500.00 you can get the ballast, bulb, reflector, socket, ect everything you need for a 1000 watt HPS or MH setup. I was wondering just how bright is 140,000 lumens? I mean if I were to put one of these things in a 14x14 foot room would I be able to sit in there and read or watch T.V.? Or would I simply burn out my eyes in pain? It would be awesome to get one of these just for the sheer power. I could even grow some veggies in there as well [img]/ubbthreads/images/graemlins/grin.gif[/img]

Hello Woodsman,

I am not sure how to get from lumens to candela, but IF 140,000 lumens put out 140,000 candela and if you had the light 5 feet above you, you would end up with 5600 foot candles on your book. I just measured the winter sun light and got close to 5000 foot candles. So your light would be a little brighter than winter sunlight around noon.

Now if you focused the light with a reflector or lens, the candela would go up along with everything else.

1000W HPS...WHAT?!?

250W (25K lm IIRC), is ridiculously bright in a medium sized room (about as bright as direct summer sunlight through the window I'd say...even if rather odd coloured sunlight!). 1000W would be something to see indeed!

you'll be watching TV with sunglasses on...[img]/ubbthreads/images/graemlins/smirk.gif[/img]
and after a while the hum of the ballast might drive you nuts.[img]/ubbthreads/images/graemlins/banghead.gif[/img] [img]/ubbthreads/images/graemlins/banghead.gif[/img] [img]/ubbthreads/images/graemlins/banghead.gif[/img]
also, these lights are meant to be hung at no less then 10'
how high are your cieling? [img]/ubbthreads/images/graemlins/grin.gif[/img]

That's one thing I love about this thing (250W), I tend to use it when I'm working inside the computer case (I do PC repairs as a hobby), as it totally obliterates all shadows in the room.

There's a bit of a hum when it's warming up, but is almost totally silent once up to temperature. (barely audible unless you stick your ear right next to it).

that one will hum too,they all hum eventually, although not as loud as the 1000W.

My ceiling is ten foot, but it wouldn't be hanging that high.
I have recently checked out the HID lights from grainger, and might end up getting one of those set-ups instead. The ones that are made for industrial warehouse lighting, they even have a 1500 watt MH!! [img]/ubbthreads/images/graemlins/grin.gif[/img]
