Lighting SupergrowLed, GiantLed, and wellparLed LED Grow lights

That's way too much, is it a typo?
Cree cxb chips are so far the most efficent leds in production and their output is around 2,5 umol/W max(when underdriven). Too bad they don't have the penetration of DE bulbs.

The spiders say they are 615umol for 90w led so that is 6.8umol/w but actual wattage is 50w so that would make it 12.3umol? They are underdriven. They produce twice the oils with a 120 degree lens. Reduce ur lenses to 90&60 degree lenses you can now increase ur penetration.

You assume the given numbers are correct, from my sources it's clear the spider numbers are wrong, no doubt.
A 400w hps emits 700+ umols and with a reflector in a square meter you get around 600-650 umols.
I don't believe for a second the spider numbers are real.

Is this the spider light?

The specs say less than 2000 lumens, no mention of par photons.

It's been proven in our trials that a spider 360w so actual power 200w matches a 400w hps in all stages of growth, excels in leafy actually. And now you can change the lenses it matches if not excels in bloom/bud compared to hps. LED will be the way of the future and there is a lot of haters out there but I've been trialing for over a year and these lights are working in Australia. These lights are growing cannabis, blueberries, herbs, Mangoes, avocados, and much more. I have not been able to grow fruit trees with hps. Not only that running cost is hugely marginal compared to using hps.

Wait, I don't get where you pull the numbers from.
You said 50W and 615umol, so why is now 200W and a 400W hps comparison..? Doesn't make any sense...

 

[Porcha1980]

Cause in trials the 200w kept up with the 400w hps

Each cob is 615umol. So a 50w is that. The 200w is that x 4 as it has 4 cobs

Totally agree here

These numbers don't make any sense. Except maybe for a 2x2 area...

So ur saying Balarama that u don't believe that 50w cob emits 615umols? Why is that? My trials with hps and LEDs, show that a my Spider 4 (120degree lenses)(360w but actual watt is 200w according to my meter) matches a 400w hps, once lenses are changed to 60 degree, (add extra Spider 1 (90w, actual drawage 50w) light for coverage) it excels pass my 400w hps.
