If you consider a strip of metal barely rigid enough to support the strip a heat sink, sure.

I don't use heat sinks unless I'm dealing with insane power. Like 1,000w in a 70mm x 70mm package.

"And she's been unwilling to loan me a unit for test purposes, dammit ;) "

Your sister does my exact job.

What sort of unit are you looking for? I've got tons. General purpose, microgreens, hell I've got technology to grow some plants without any light at all (very useful for the cattle/sheep ranchers) with a 99% reduction in water requirements.

"If you've got evidence to show, please share....our electric bills will thank you"

Sure. http://ledgrowersforum.co.uk/

How about a cola as big around as my leg?

In that case, it would be worth it for some deep pocket investors to gain control of the board and drive a split-up.They'd get a 25% return for it; that they haven't may mean either no one can put together a del enough set of pockets to be able to force a breakup or they rely don't think there is such a premium.

"LEDs aren't there yet. You can't get cannabis to flower properly under LED lighting, nor can you get the sort of growth rates you'll get under HID lights"

Yea, explain why I made it on High Times Pix of the Crop six years in a row using pure LED lighting.

Or how about you go roll over to http://ledgrowersforum.co.uk/ and learn how dead wrong you are.

That's when you do an LBO, liquidate the company and pocket the difference.

"The parent post already stated HPS and LED lights have near the same efficiency..."

The parent post is wrong. Wikipedia is a horrible source for the rapidly-evolving world of semiconductor lighting. I've already got LEDs with 200+ l/w efficiency (Cree MK-R.) In single color LEDs, going to equal weighting and ignoring the weighting of green, you might as well just say 330+l/w, which is double any HID (excepting the almost pure-green low pressure sodium lamp, which can do 220+ l/w.)

"HPS is in the >100 lumen/watt ballpark"

Only in their more inefficient ranges like 250 and 400w. 600w can get up to 160l/w.

"LEDs, while capable of much more efficiency when operated at currents below their maximum ratings, usually operate near the same 100lm/W efficiencies when operated at maximum current"

Current LED tech is 130+ l/w and Cree's already popped 200+ at room temp 5600K 80mA drive with their MK-R, and in the lab, they've already hit 303+ at room temp 5150K color temp and 350mA drive.

" But a 400W LED fixture would produce nearly the same heat overall. It just wouldn't get as hot ;-) "

Comparing 400w HID to 400w LED, full power, the LED will produce on average 15-20% less heat, with that heat difference made up as light output.

"apparently you have no idea just how much heat LED arrays put out."

I design LED systems globally, son.

Try again when you know who you're talking to - THE LED expert on this site.

And a hydroponics light is a bullshit term because there is no specific light for hydroponics alone.

Many people think a light is either specifically for hydroponics or soil. It's neither. It is a horticultural light. It will grow anything that will grow under the sun, regardless of hydro or soil.

The joys of misleading marketing.

It is the market that will determine whether Tesla has potential, not its competitors.

I think you're not understanding my words.

First, I'm mocking the term 'hydroponic light' as if the water were generating light. Then I go on further to explain that the only way they'd get light from a liquid that would even be usable enough for horticulture would have to be produced by sonoluminescence, which is highly inefficient and wouldn't produce the kind of heat (let alone light) an HID bulb would do, which is how these people are getting caught by drones using infrared thermal cameras.

"They require hydroponic lights for the marijuana plants to grow"

What the fuck is a hydroponic light? Are we talking sonoluminescence or what? That's gotta be inefficient.

You mean an HID light, which produces tons of heat and is easy traceable from both ballast noise and heat.

Shoulda gone LED, suckers.

True. Putin is very good a looking out for Putin and surviving. Right know, Putin can hold the specter of a trail and imprisonment over him as motivation to do what he is told. As long as Snowden is useful to Putin he'll be kept around and trotted out like a show pony. Once having him around is a liability or Putin can use him to achieve some more important end Snowden will be cut lose. Putin could simply decide to "follow Russian law" and deport him. Snowden is only safe in Russia as long as he is valuable and given his propensity to become disillusioned or get angry if he is not viewed as valuable he may very well wear out his welcome as well. Make no mistake, Putin has nothing but disdain for Snowden but since he is useful he keeps him around.
