My 400w EDFL is 130'-202' f depending on where I test it.
my 150w Cmh was 250' F
I haven't tested the hps I also had in the cab.
But they were scorchers for me.
6-8 in from the tops would burn em with out glass and fans.
Edlf is a great small space scrogers light.
You can buy longer wires to remote locate the ballasts.
I like mine better than my lil HIDs so far.....

The Emerson effect.
When Emerson, a scientist, exposed green plants to differing wavelengths of light, he noticed that at wavelengths of greater than 680 nm the efficiency of photosynthesis decreased abruptly despite the fact that this is a region of the spectrum where chlorophyll still absorbs light (chlorophyll is the green pigment in plants - it absorbs mainly the red and blue wavelengths from light, leaving the green light to bounce back and hit our eyes). When the plants were exposed to short-wavelength light, (less than 660nm), the efficiency also decreased. Emerson then exposed the plants to both short and long wavelengths at the same time, causing the efficiency to increase greatly. He concluded that there must be two different photosystems involved in photosynthesis, one driven by short-wavelength light and one driven by long-wavelength (PS1 and PS2). They work together to enhance efficiency and convert the light energy to forms that can be absorbed by the plant.[1]
The light excites the chlorophyll molecules at the reaction centre and causes an increase in energy. As the molecule becomes less excited, its energy is transported through a chain of electron carriers to the next photosystem which does much the same thing and produces energy-carrying organic molecules.
(enhancement effect) The observation (made by Robert Emerson in 1957) that photosynthesis, which proceeds very slowly using light of 700 nm wavelength, can be greatly increased when chloroplasts are also illuminated with light of shorter wavelength (650 nm). This was a surprising observation as it was then thought that light absorbed by the chlorophylls and other pigments was all passed on to a small percentage of chlorophyll a molecules (the energy trap) absorbing at 700 nm. This and later work indicated a second energy trap absorbing at 680 nm. See Photosystems I and II.

if i may, i don't think it's that "elusive"
plants evolved after bacteria, halobacteria were here first, and are purple (due to retinal), and photosynthesize more according to the graph below:
so dig it... then algae n shit start to evolve after the halobacteria. they would have done so in lower water strata, which would have already had it's green light filtered out by the bacteria in the shallower water above. so they evolved to use the spectra that the bacteria weren't using. when plants came out of the water and into the air, they didn't have to compete vs bacteria for light based on first exposure, but were still able to get enough light with the red/orange/blue/violet sensitivities. so plants stayed green.
at least that's the nutshell of what i was taught in Botany.

^^^^ found that thread. Back in 2007 with 1200 watts of induction. ..... All the bulbs looked the same. Miss j only said they are 200w each and that they are induction.but not much else about the lights. From the pics of ballasts she had on the wall they look like they could be lvd.

My 400 w Riant purple grow light is rated at 25000 lumens.
There regular non grow 3600-5500k is 1/3 higher in lumens.
The dual specta grow bulb purple may not be as good as 2 combined veg an flower lights due to the loss of lumens?

Hey Scar. There really needs to be a term in plant lighting that is not basing the lamps output on a photopically corrected visual value like lumens. We need a measurement that would be described as maybe a PAR-Lumen that would give more weight to the lamps output in the 380-520/610-720nm regions and less weight to the 520-610 nm regions. The post you reference is right in that mfg stated values can hurt induction technology when they don't produce crops that compare or better in weight and quality those crops grown under higher heat/wattage HID lamps. Lumens and kelvin values that purport to make one induction lamp better than the competitors continues to perpetuate this obfuscation. But at the end of the day you're happy with your results with your setup than good for you.

A lightbulb powered by radio waves
August 23, 2007 | Michael Kanellos
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.
luxim
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.

Interesting stuff....Im assuming the 70 lumens per watt for LED's is 2007 data aswell?

Kite 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'.

Aloha, Where can you buy the Blue Dream 800 watt induction light? Please lead me to the manufacturer. Thanks
