Lighting Induction lighting revisited

[lazylathe]

Took a while... but here is my two week findings!

First the very un-scientific set up!
Just to show light heights, as there is light bleed everywhere...

And the Induction seedling

And the LED seedling

Cool
Ill be watching

How many watts led vs EDFL?

I get my induction closer if ya can? 2-3 in?
I run 4-6 in from my top usualy with a 400w light.

Hey Lazy, is that the distance you keep the LED's from the seedlings? I have been apprehensive about starting them under my LED's but it looks like you may have it wired. Thanks for the comparison test, bro!

The Induction is about 3 inches from the top of the seedling, measure it last night.

As for wattages:
LED is 315 so in reality about 280W
Induction is 250W

Distance for LED's is very important and i find it tends to vary with every strain, some can handle them a lot closer.
For now these guys seem to be pretty happy at the current distance.
I like my plants to be short during veg as they are easier to handle during bloom.

I'd say just go for it and try your LED's over seedlings, start high and work your way down till they are happy!
Also depends on the type of LED's you are using.

That's kinda what I thought... I'll just keep using my T-5's in the nursery for now, until I get my feet under me a little better. Thanks bro!

hey lazeee! how are ya! thanks for briniging this info to us! playing devil's advocate it looks like the plant under the led's has twice the mass as the one under induction. i read through the intire thread and on one page you said you wanted to sell your blackstar's?? did you? if not i would hang on to them!: what model led is in the comparison shot? is it a bs chrome? two more question's come to mind. how much for a new ind bulb? if you break one. and as with fluro's filled with mercury induction if broken can be toxic. i have subbed up to follow your thread:smokebuds:

Hey Astro!!!
Going good on this side, how about you?

And now for some answers!
1 - Mass is almost twice, maybe a bit more for the ones under the LED's
I will take a top view shot tonight and post it, there is a massive difference!

2 - The BlackStars were sold to a friend who wanted to try LED's
They are working out well for him and he is very happy!
I should have kept them though...:Stones slap:

3 - The LED's i am using are from Bysen LED, 315Watt models so in reality about 280Watts.
This is a link to a thread i started about them, all the trials and tribulations of buying from China!
Great lights, i am thinking of adding a third panel and selling the Induction for the next grow!

4 - A new Induction bulb would run about $200 to $250 for a 250Watt.
The mercury is a problem but they are designed to last for up to 100 000 hours of use, i just be very careful around it and try not to bang it!
On another note these suckers emit a lot of heat!!!
Way more than the bigger LED panels!

Maybe follow this one?
https://www.autoflower.org/f126/coco-adventures-21198.html
It will have more pics and details of the entire grow!

How much were the led panels?

Do you know the lumen per watt?

Are they all the same age strain ect.
The induction one looks like a lagger?
With induction an cfl I can keep node spacing like the led grown.
Maybe put one of the 3 super healthy ones under the EDFL.


I'm going to get a 200w unit from Riant.
I think He quoted me 180$ grand total for one of his red specta lamps.
But alibabba has 400w lvd lamps for 180+ shipping.

Flouro induction and flouro run at about the same temps.
My infrared thermometer says the bulb is about 135" +/- 10'.
Led have their own heat issues, they relly on heat sinks an fans for operation.

And regarding the mercury.

In the January 2011 issue of Environmental Science and Technology scientists from the University of California Irvine and Davis discovered that some LED lights contain up to 8 times the amount of lead allowed by California law. Nickel contaminants were also found to be present in LED lights along with arsenic, copper, and other metals closely linked to different cancers, neurological damage, kidney disease, hypertension, skin rashes, and other illnesses in humans, and to ecological damage in waterways.
The study suggests that a special broom, gloves and mask should be used when cleaning up broken bulbs in households. Also, crews attending to car accidents or broken traffic lights should wear protective gear and treat any broken bulbs as hazardous waste.
LEDs are currently not classified as toxic, and are disposed of in conventional landfills.
RECYCLING LED’S AND THE ENVIRONMENT
Because magnetic induction lights contain a solid Mercury amalgam attached to the outside of the bulb (rather than the ever popular quicksilver beads of Mercury used in the most common of lights) recycling is simple. When the lamp goes out, the Mercury amalgam can be removed within the glass casing with a pair of pliers and recycled separately from the bulb itself. The electronic ballast and the magnets can be reused. This means no liquid Mercury being released into our environment.
Contrary to popular belief, LED lights are NOT easy to recycle due to the circuit board they are housed in. The circuit boards require numerous raw materials to produce and LED manufacturing has more negative environmental and health effects than any other lighting technology.
