hi, wondered if anyone could give me the any advice they have concerning sulphur plasma lamps. Anyone got one, do they come in different spectrums like CLFs, and anything else you think i should consider.

i heard of them, i dont think they are for sale to the general public yet....... but those are some crazy lights!!

As of recently the only company producing those lamps is LG Korean division for use in street lighting and other outdoor lighting. The company that originally kept the ball rolling was Nurturelite, but they had very limited distribution and no warranty as they described their products as "experimental." The best place to learn about this technology is Wikipedia:

Sulfur lamp - Wikipedia, the free encyclopedia

Although looking at it now it's less comprehensive than it used to be... hmmm. Well I can tell you that it's not even worth a second glance in terms of your needs right now. These lamps are still problematic and cost thousands while emitting electromagnetic interfearence that can really mess up your satellite tv, cell phones etc. You will never get one so don't even try... believe me I did for months.

Cheers for your input fellas, looks like I am 10 years too early - hopefully they will sort out the problems with these lights soon as they are a seriously good light source.

don't hold your breath... any lighting system with moving parts, let alone a high speed motor, will never gain the popularity it deserves. Simply too much sound and maintenance. Plus there are two parts that can burn out, the magnetron AND the motor. If the magnetron burns out it pretty cheap but the motors for these things have to be precise and don't come cheaply... plus if that fails the whole thing can go BOOOOM!

im no expert but the light emited from theese aint even the right spectrum less than 1% uv? hardly any red all green and yellow ive seen and am attempting a grow with only red and blue leds (and maybe a uv flouro if im lucky) so all this yellow and green dont seem like a good way to spend my lecky bill i also read somewhere that green light causes stretching of the plant

on the ebay listing he said that it emits the same spectrum of light as the sun. the sun emits light in all color spectrums.

i don't know though, but it would be pretty cool to run a light like that. i saw a video and it looked pretty bright. for a video anyway.

i seen the vid and it does run bright but i aslo read where it said less than 1% uv and mostly green which i heard causes stretching and uv helps convert other canibinoids to thc

Sulphur Plasma Light

The sulphur lamp (also sulfur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulphur plasma that has been excited by microwave radiation. The technology was developed in the early 1990s, funded by NASA and the US Department of Defence for anticipated extra terrestrial operations. Star wars program and funding for sulphur lighting was terminated by 1999. Since 2005, lamps were again being manufactured for both research and commercial use by Island Systems in Essex, UK.
Mechanism

The sulphur lamp consists of a golf ball-sized fused-quartz bulb (1) containing several milligrams of sulphur powder and argon gas at the end of a thin glass spindle. The bulb is enclosed in a microwave-resonant wire-mesh cage (7). A magnetron (4), variably powered by a digital electronic PSU (5), bombards the bulb, via a waveguide (3), with 2.45 GHz microwaves. The microwave energy excites the gas to several atmospheres pressure, which in turn heats the sulphur to an extreme degree forming a brightly glowing plasma capable of illuminating a large area. Because the bulb heats up considerably, it is necessary for an electric motor (2) to spin the bulb while a fan (6) cools it to prevent it from melting.
The bulb can be placed at the focus of a parabolic reflector to direct all the light in one direction, deeming it probably the only light source small enough and powerful enough for practical and commercially viable light pipe applications
It would be impossible to excite the sulphur using traditional electrodes. The sulphur would quickly react with and destroy all metallic electrodes rendering them useless. The absence of electrodes allows for a far greater variety of light-generating substances to be used than those used in traditional lamps.
The design life of the bulb is greater than 60,000 hours. The bulb emits no electric or magnetic fields. The quality of light reduces by up to 5% in the first 100 hours of operation and then remains constant for the next 5 years.
With the exception of fluorescent lamps, the warm-up time of the sulphur lamp is notably shorter than for all other gas discharge lamps, even at low ambient temperatures. It reaches 90% of its final luminous flux within twenty seconds (video), and the lamp can be restarted less than five minutes after a power cut.
Our first prototype lamps were 1.18 kW units, with a system efficiency of just over 100 lumens per watt. The first production models were 1.36 kW with an output of 191,000 lumens.
Quality of Light Emitted

The sulphur plasma consists mainly of dimer molecules (S2), which generate the light through molecular emission. Because this, instead of atomic emission, is the mechanism of light generation, the emission spectrum is continuous throughout the visible spectrum.

The lamp's output is low in infrared energy, and less than 1% is ultraviolet light. As much as 73% of the emitted radiation is in the visible spectrum, far more than other types of lamps. The visible light output mimics sunlight better than any other artificial light source, and the lack of harmful ultraviolet radiation can be especially beneficial to museums and displays of art.
The spectral output peaks at 510 nanometres and the correlated colour temperature is approximately 6000 kelvins with a CRI of 79. The lamp can be dimmed to 15% without affecting the light quality, and light output remains constant over the life of the bulb.
The use of a magenta filter can be used to give the light a warmer feel. Such a filter was used on the lamps at the National Air and Space Museum in Washington, D.C.
Because the lamp is electrodeless, the addition of other chemicals in the bulb can be used to change or improve colour rendition. Sulphur lamp bulbs with calcium bromide added produce a similar spectrum but with the addition of a spike in red wavelengths at 625nm. Other additives such as selenium indium halide, lithium iodide and sodium iodide can and have been been used to modify the output spectra. (see SPD chart from Jena Uni)

these use the luxim light correct? i looked into getting a kit and running some test. the lights alone are 600 each. quite a lot for a 300 watt light. at wholesale. then you need to get the controller and software another 400. your price is about right.

do you get the same weight from less wattage than HPS? what are the grams per watt?

i was thinking 1 light for a 2 x 2 area when i was looking. if you can get the same harvest from 2 as a 1000 watt HPS it will take about 2 years to recover cost through electrical savings. 4 as i was thinking was not cost effective, unless the harvest was doubled. like 2 grams per watt.

look forward to seeing test results.

Hi all :-) here is the link where they are for sale http://www.tradehydro.com/products/psh700-series-sulphur-plasma-730w.html Anyway I spoke to the guy at the dealers and he was very helpful and honest. They cost somewhere in the region of £800, and they do them in the spectrums of 9500k 6000k and 4000k. The 4000k is being sold by a German growshop as a growlight as that spectrum is like a an enhanced spectrum HPS used for Veg and Bloom. The light can be used to grow an area of 6M2. So that's pretty much it,,,,,I'm buying one as soon as possible. Peace all ;-)
