Question on Spinning Lights?

[Bogey]

I just came back from the hydro store and for the first time saw a completely new setup....Seems they have a spinning light setup on an adjustable pole where the lights can be very close to the plants. The whole reflector spins 360 constantly which they claim elimanates any heat.....Connected to 2 digital ballasts with 1 mh and 1 hps the unit ran around 1750 USD Has any had any experience with this unit and does it make any significant difference?.....

[c-ray]

was it called a 'sun circle'?

[hydrorascal]

a link would sure help too....

[pugs]

maybe this?

imo the best reflectors out there are the grostar shades, they are cool to the touch after hours of use, and they give very nice even light distribution over the canopy.....

Joe....As the equipment Guru here....Do you have any input?......

[Joe King Park]

Er, me ?
i do recall seing them, but i cannot see the benefit from using them
its like those first generation digi ballasts from home hydro with the tiny one inch fans inside
" a product is only as good as its weakest link"
i have used lightrails in the past and they are perfectly fine, and cost pennies per year to run , whilst also allowing you to place your lamp 30% closer to the tops of your plants !! ( 30% more lumens ?)
apparently , in test studies done by Jorge Cervantes, The Adjustawing , the new avenger version ( glass powder coated reflector is the best for spread and also for low mounting heights
www.hydrogarden.com or www.hydroleaf.com sell their own version called a mantis "adjustashade" , which is a copy
and shortly a larger 1000 watt adjustashade is being released

the reason i have moved the discussion to such shades , is if strategically placed , then no movement is needed
but then again a adjustawing mounted on a lightrail would really be a productive set up
as always i do have some images still kicking around
lets see what i've got for this post

Hot stuff !!!!

Joe....Er think your missing the point here....Studies claim that with movement very little heat is generated and with dual spectrum MH and HPS you get a full spectrum for growing with a larger area covered.....Supposed to increase yield due to these factors....Or am i missing something in your reply....With my limited brain function that would be a given....

[Carpet Muncher]

larger area covered? wouldn't it be the same as 2 on a rail?
got a round room? i don't. :)

yeah they spin real fast! From the corner of my eye I thought it was a cop(I swallowed the roach) until I looked over to the hydro store and the flashing lights were coming from inside. So I went inside and said "WTF????" They told me they were digital 400's and the entire unit was ..........Gulp!...............45 fuckin hundred bucks!!!! So I asked them how many they've sold, and they said none. LoL Gee....I wonder why??????

[Joe King Park]

the only benefit i can see is the bulbs "may" run cooler
but won't if you don't have an extractor !!
light waves travel on their own , and by spinning them around fast does not neccesarily mean they will give more spread or penetration than an adjustawing strategically placed
a lightrail driven 1000 watt will increase your High Light grow space from 5 X5 to 10X10
for $4350.00 less
thats very pricey considering you can get one of these for less www.vb1000.com

just like the Vertizontal shade, i don't see its benefit
just my two cents

i don't know if you already know this , but i'll retype it anyways, since we need to repost it
The Inverse Square Law
The distance between the light source and the plant can be crucial !
We don't want to be too close or the plant will overheat, be stressed to the point it stops growing , and worse, death of plant

We do not want the lamp too far away from the plants, as the result would be a Massive loss of Performance
This is due to the law of physics
The Inverse Square Law applies to the " Movement of Light Energy through the Atmosphere. This means that the Light Energy available is in Inverse Proportion to the Distance it has Travelled.Or , put another way;
If a lamp was two feet away from your plants, loss of efficiency will result in your plant only recieving 75% of available lumens
if the same lamp was 4 feet above your plants , then they would only be recieving one 16th of available lumens.

i have a chart here which shows you suggested lamp distances;
( if using a light mover you can lower your lamps another 25-30%)
although these figures are fairly accurate , please bear in mind that adequate air exchange, and other elements are dialled in.

Milwaukee make a nice Lux Meter , and also very handy is a hand held laser temperature guage; just point at top of plant/cola and you get a very accurate temperature reading.
with one of these you can totally eradicate hot spots in your garden, whilst also using it to tune in your garden for optimum results.

sorry , one question i did'nt answer Bogey; instead of using a metal halide and a HPS, why not just run two UV enhanced Grolux Bulbs instead
you'll save a couple of dollars and also gain an extra 4000 hours bulb life

also Son T Agro's pump out an extra 20-30% UV (Blue Spectrum- vegetative growth), and although a little pricier, you can opt for the Vialox Nav T Super ( elements sell a 400 Nav T for under £20.00 ) !!!

Bogey, i know this is a personal question, but do you have your heart set on buying this system ?
the reason i ask is i have not heard, nor seen any postings on its performance
no grow reports, nothing !!

i could suggest several different options if you'd like
depending on your set up

...back at a hydro expo in vegas a guy had something similar...his was called the day star...good guy...

...i'm not sure if i'm convinced of their benefits but i will say this...at an HMA (hydroponic merchant association) trade show, with everyone showing off their fancy systems(including me)...his plants were the healthiest after 4 days...mine looked like shit...

[Hank Hill]

Less heat would mean less light over the plants, so there is a tradeoff, I guess

[ihaveworms]

i saw it a couple years ago acutally... it looks like a large ceiling fan.. and spins pretty quick... seems like another hype product as he said it was "ok at best" ... so... that kinda money.. you could make a killer setup bro ;)

JKP....No i wasn't buying the sysem joe i was just curious if any one had any experience or personal info on this system....Seems good in theory i wondered if it worked i n real life situations.....

[Papi]

I remember many years ago there was a spinning light set on the market, and I remember reading that the speed of the motion made the bulbs burn out quicker. This was a long time ago so I don't know if this would apply to the present day situation.

Delta ....Did the lights enhance yield or health?...I figure they are waiting a week or 2 to test potency but curious if the yield or health was improved?......

.7 gpw doesn't sound worth it to me. Gotta get at least 1 gpw for me to think about it.

[Agent-Smith]

Well it sounds a little better since you mentioned strains but a side by side is still needed.

[BravoC.D.]

i want to say the reason these spinning light with a mh and hps is to get what the sunlight throws off. from what i've gather for everyones inpput is that a plant need both blue and red rays. yes it's been known that the plants during veg love the blue light. but their is more lumens put off by an hps and with an mh also adds to the lumens beening brodcasted out to the plant in turn keeping a shorter node. thing is to know make that into turth, that would need a illustrating with different rooms same temps and different situations in other grows. i would love to do something like that, what u all??? enjoy the light out there, i have to say that is something else to state and see. stay safe, bravo
