About those LED lights

[BigBlock]

I'm glad you finally understand the heat generation issue.

There is nothing I do not understand. Watt for watt, LEDs provide less light and more heat. Whether it's 6 watts or 600 watts makes no difference. Just because you choose not to believe the facts does not make them untrue.

bah, maybe you'll get it some day...

Guys, please...

Look, BigBlock has his view, and other have theirs...

More friendly guys! If this guy bought the LED lights, lets see his grow... let's give it a chance...

If at the end BigBlock was right, well, good! If he was wrong, good as well!

The way I see it, the hobby is all about experimenting... Of course, you use the experience from others... but, I think experimentation is key.

Let's see how the LED grow goes!

Hey BigBlock,

You're a Lighting Engineer... right? Well, question: Why the hell can't lumens be added up?

From what I understand, if I have two 1000 lumens bulbs, I'll have... 1,000 lumens... not 2,000... no... 1,000.... why?

I'm pretty technically/chemically/physically/stonedlly inclined, so please feel free to use terms and concepts... but I still don't get it... why? 1 + 1 = 1?

Why the hell can't lumens be added up?

They can. Two 1000 lumen bulbs = 2000 lumens. Light intensity is what cannot be added together, for example, two 125 watt HPS bulbs would not have nearly as much penetration as a single 250 watt bulb, because the light is coming from a larger area.

Well, if that doesn't work I can guarantee the sulphur microwave lamp will blow the doors off of HID and it won't produce much heat at all, like 100 degrees.

PAR ratings are off the scale too. They cost $1600 USD but there is no doubt it's better than HID lamps.

I'm willing to shell out the money for the sulphur microwave lamp... but, I think it's like 1,600 British pounds... isn't that like 2 times (or 1.8?) times the US dollar? Around $3,000 I think...

In addition, in the future, when/IF I buy it, I'll definitely be shipping to another state (a friend) then have him mail it to me... I see the market too small to buy that thing then post here that I bought it... dead giveaway...

One thing I need to see how it'll work out, is the RF interference... supposedly, it wreaks havok in electronic equipment nearby....

Yes, it does wreak havoc on the 802.11 standard, which is why it never took off. However, if you don't wireless network and you are away from hotspots there is no better light, LED or otherwise.

Oh, I believe the confusion is that both BIGBLOCK and smoknjoe are right. LED's are not as efficient as HID. However, HID's create too much light that plants can't use and this gives them a higher lumen and heat rating. The LED's used for plants only focus on the light temps that work for plants. Lumen's are for humans and PAR is for plants. Most of the LED systems light cannot be seen with the human eye but plants use it very efficiently without energy wasted on the plant useless spectrums.

I have been in personal touch with Island Systems and their price for us is in US funds. They will have some cannabis pics soon.

Peace.

US dollars? Damn... then, I'll be taking a definitely closer look... for real.

As to the cannabis pics, if that gets posted, it'll be a hit with no doubt.

But I'm wondering... they should do that shit very cleverly... I don't think it's a good idea to explicitly say your lights are great for growing cannabis.

But they can create an account (no connection to the Company) and post the pics... that'd be great!
