Does 5.167 ring a bell? I like pictures.

To be clear I meant banshee as in ghostly fairy woman. https://en.wikipedia.org/wiki/Banshee

Doubtful. Still not impressed. :roll: Holy shit HolyGhost have you lost your mind?

I own @robincnn and @Stephenj37826 an apology for the above post. Sorry... I was missing something. I did not consider that everyone does not have the tools and know how to build a fixture. HLG is not a charlatan vendor which puts them in a very small class of vendors. They provide a good...

Are your parents siblings? 100,000 sperm, how were you the fastest?

Not impressed. Ghetto, that does describe you. HolyGhost? More like DepravedBanshee,

Little more than that. a bunch of photons. lotsa photons. jillions and zillions. 1 µMole = 602,000,000,000,000,000 or 602,000,000,000 million photons. 602 zetta-photons 602 sextillion photons

If the time is 1 sec., photons / watt/1 sec. = photons per Joule.

For $20 you could buy three 28W (14 typ.) Bridgelux Gen2 strips (180 lm/w) including FedEx overnight shipping.

You nailed it. The Luxeon Red Meat is very similar. Peaks at 635 nm in radiometric watts and 602 nm in Lux.

That's just wrong. WTF is wrong with you?? Wiping your ass with a $20 and dropping it in the toilet would be a better value than using it to buy this fixture.

LER is luminous, it is not relevant. A OSRAM SSL Olson Hyper Red output about 70% radiant power compared to electrical watts. For the Luxeon Fresh Focus Red Meat L2C5-RM001211E1900 43,610 lumens = 215 radiometric watts = 1120 µmol/m²/s PPFD. The following graphs were created from the...

Watts means very little. They do not state spectrum, CCT,, CRI, or efficacy. Wall watts includes the power lost in the LED driver. A 30W CoB for $13 is not a good price. It does include a reflector but it is of very little value because CoBs do not need a reflector. A CoB does not shine its...

What kind of efficacy is measured in percent? Luminous efficacy is measured in lm/w. So what are you referring to? You cannot use lumens. Red @ 650nm 1 µmol/m²/s = 13.4 lux. Green @ 550nm 1 µmol/m²/s = 147.2 lux About a 10x variation based on wavelength.

Provide a citation. Dumbass! It does not. See also Emerson red drop effect. Through chlorophyll. Yes it is, disregarding carotenoids. See also photoreceptor proteins. Fireball is kicking in, out the door to shoot pool and sing karaoke. One of these days...

I like you. I have been waiting on you to chime in on this one. Although the photochemical quantum yield under optimum conditions is nearly 100%,... I purposelessly left off the next step which you previously call em out on. ..the efficiency of the conversion of light into chemical energy...

You are too predictable. You cannot answer, and instead sling mud. Mr. Ad Hominem. The terms before the units of measure are called quantities or derived quantities. You must have delusions of adequacy. Are your parents siblings? Attached is the SI system of units PDF, educate...

ChiLED are very good at what they do. Possibly the best. Their engineering is superior to most every other vendor. They got caught up in the details. They wanted perfection. People are not willing to pay for perfection. People buy cheap Chinese shit. Real shit. The charlatan Chinese...

You are very likely smarter than these other twits. They may be smart (doubtful) but it is looking less likely the more they say. The problem is they are ignorant. They decide to ignore the facts and not verify what they think is wrong. Ignorant. I have posted the sources of my...

Units of measure were in parenthesis. What would you call the terms preceding the parenthesis?
