Green Light Drives Leaf Photosynthesis More Efficiently than Red Light in Strong White Light: Revisiting the Enigmatic Question of Why Leaves are Green

I am in the lighting business and want to clear up some claims that are posted about these "super grow" lights. These lights are a purple violet color spectrum induction light. The problem with them is that in order to produce this color spectrum, the glass tubes used in the bulbs is coated with phosphorus so thick, it blocks out most of the lights output. A better bet is to find a induction light at 2700K and 6400K. These induction lights produce almost four times the light output of the purple color ones. The 300 watt purple produces only 12000 lumens the 6400K and 2700K 300 watt light produces 45000 lumens for better light penetration. 2700K and 6400K color fluorescents are already successful in CFL grow lights. The only problem with the CFL's are they don't put out enough light for good penetration yet a 250 watt cfl still outperforms a purple spectrum induction light at much lower price. It's not just lumens the purple spectrum is lacking in but also Umol (PAR) light too. Our test show that the purple produces less than half of the 6400K induction. I am responding to this thread because we don't want these Purple induction lights giving induction lights a bad name and growers giving up on induction lights. We believe induction lights are the future in grow lights and in industrial and commercial lighting applications. It was a great idea to produce a full spectrum induction light, unfortunately it needs to be improved so that it can produce better light output. standard spectrum induction lights also come in 40 to 500 watt versions. The 500 watters produce over 96000 lumens approaching the output of MH 1000 watt bulbs but with more PAR spectrum light than the MH. The best feature of induction lights is that they last 100000 hours with low light degradation. That's over 27 years at 10 hour cycle 365 days a year!! It would be the last grow light you will ever buy!! Check out this link www.enviro-techlighting.com

In April we travelled to China to inspect the product and manufacturing facilities of five top tier induction lamp providers. This trip affirmed our confidence that the induction lamps we had been supplying to that point were indeed the highest quality lamps in mainland China. But we also found these weren’t the best in the world. That title clearly belonged to AMKO Solara in Taiwan whose ballast, lamp phosphor and reflector technology were all well ahead of the nearest rival.
The only question to be satisfied with the AMKO Solara product was whether it represented value for money for our clients. Endura Light conducted further research and testing and ultimately validated that we can always install a lower wattage AMKO Solara lamp to achieve the same light output as the next best induction lamp. This further reduction in energy savings results in similar or better payback periods than cheaper alternatives. With a lower lifetime cost of ownership AMKO Solara fixtures offer a far superior financial proposition. In fact the lifetime cost of ownership of an AMKO Solara lamp is 17% lower than the next best option in a typical high bay lighting application, and a massive 61% lower operating cost than a typical metal halide lamp.
Some of the key differentiators of our AMKO Solara induction lamps over cheaper products are:
Reflectors purpose built for induction lamps to provide superior light output and spread patterns to ensure optimal light output for power consumed
The option for a Nanoflex coating inside the reflector to further increase light output and dispersion
Commercial grade components throughout the electronic circuits to ensure longevity – a 100,000 ballast comes as standard
High quality electronic ballasts with good heat dissipation from key internal components to ensure long life
Thermal separation of the ballast housing from the lamp reflector in high bay fittings to minimise heat transfer to the ballast and extend ballast life
Induction coil housing designed to dissipate heat to improve efficiency and prolong life
High quality Japanese phosphor to ensure high lumen maintenance and minimal colour temperature shift over time

Interesting stuff....Im assuming the 70 lumens per watt for LED's is 2007 data aswell?A lightbulb powered by radio waves

Forget that electrode splatter. To make light, you need RF and a special designed cavity.
Most lightbulbs create light with a pair electrodes. Luxim does it with radio waves.
The Sunnyvale, Calif.-based start-up has come up with a way to get rid of the parts inside of high intensity discharge (HID) lamps that are often the first to fail. As a result, Luxim's LiFi (light fidelity) lamp provides more lumens per watt and lasts longer than competing products, according to the company.
Your fancy lightbulb, sir.

In traditional HID lamps, high voltage pulses pass between two electrodes. The energy creates plasma from the ambient gases trapped inside the bulb and you get light. The electrodes, however, degrade over time. Tungsten splatters off of them and blackens the surface of the bulb.
By contrast, the Luxim bulb doesn't have electrodes. Instead, a radio frequency amplifier pumps RF waves to an antenna inside a resonant cavity. The interaction between the waves and the crystal cavity convert trapped gases into a plasma.
"The structure creates a concentrated electrical field in response to a standing wave," explains Julian Carey, vice president of sales at Luxim. "It creates a plasma inside a quartz capsule."
Luxim's bulbs get 120 lumens per watt, thus making them more energy efficient. By contrast, many HIDs only get 90 lumens per watt. (Top-end LEDs crank out around 70 lumens per watt). Light sources are big with investors these days.
Panasonic has inserted Luxim's bulb into projection TVs. It can also be used in projectors. Investors include Crosslink Capital and Sequoia Capital.
"It has a 5X lifetime" in projectors over regular bulbs, Carey said. "The lifetime of the light source is as long as the projector itself."
Radio waves are part of the electromagnetic spectrum (so says the Harvard grad at the desk next door) like visible light and microwaves. But they have a different wavelength.
You know not of what you speakThat title clearly belonged to AMKO Solara in Taiwan whose ballast, lamp phosphor and reflector technology were all well ahead of the nearest rival.
Expound upon that please kind sirYou know not of what you speak
Foud this today....
CREE Breaks 254 Lumens per watt with LED's.Interesting stuff....Im assuming the 70 lumens per watt for LED's is 2007 data aswell?
was just wondering...not buying anything but replacement bulbs when needed for a whileKite this is one you don't even want to know about bro. The shit these guys do is insanely stupid. And they know it. Try and buy AMKO Solara in the USA. You may get it through a back door but they will not sell it through legitimate US distribution partners. And no matter what you decide to do Brother Kite just remember 'I told you so'.
