What would your dream light setup be...if money was no object???

Also could I spend some money on solar panels as well? That way I could charge with POCO supply or with the sun, then I wouldn't have to pay for anything?

Not really what I was going for. But it really doesn't matter unless your choice is really inefficient, because the 2000w is the biggest limiting factor.

What I find interesting is that everyone but dawg would use pretty close to the full 2000w. With current tech and what I have seen I think with good led's/units 55% can be the same as 100% of hps. Example...1000whps is ~equal to 550w of top quality/performing LED's.

Dawg your goal is totally possible and why I believe in led's.

I would be using the all of the 2000 watts all of the time, any power that is not going directly into the lights will be getting stored for later use, how is that not using the full 2000 watts?

The reason I said start up was free was so that people would say what they really thought they needed and not skimp out.
2000w is what hps would use to light up the space. In theory LED's could do it with less(much less), and what I was hoping people would have tried to show.
Solar panels are a power system, not a light system. You are trying to find loopholes but you don't need them. You're always limited by 2000w of output...even if you have stored energy. And like I was saying the whole 2000w is not necessary when using LED's.

For fun, lets say you have solar and it's free to run shit...would that make you choose hps?

Yes I see your point, but I was taken advantage of the fact that LEDs run off DC power not AC like normal HPS lighting systems and powering the LEDs straight off of stored power in battery's could be more efficient then any other system.

So another solution could be slow charging the battery's throughout the day with a small amount of POCO power, and then just using what you need. You would have to see if the the DC LED drivers and battery charging rectifier would waste less power then the HPS digital ballast or AC LED drivers...

No LEDs would work better with solar power, its stored as Electrochemical power in a battery cell or electrostatically in a capacitor before use and converts directly into almost purely DC current, better for LEDs, unless they make DC HPS lights which I don't think they do, so you would have to use a DC to AC converter to drive them which would add to the losses in the system.

If money was no object, of course people are going to max out what they can use. lol

we are on the same page....i have a couple of movers for the next round....these inductions are outperforming my expectations.

With a biofeedback programmable system you wouldn't have to always use the 2000 watts, but it could be available.

Tags thanks for the neat thread it made me realize I actually do have my dream 4x8 setup lol except for the pontoons.....I would like to add sola tubes as well since we are dreaming and all lol..........http://www.solatube.com/

If money was no object, I would engineer a plasma light source that I suppose would be 2k wattage equivalent.
It would have to run on under a dollar a day in energy costs.

Tags what did you think of my other idea of using 64 Cree globes vertical style . 608 watts total. For each 4x4. Running 16 vertically in the center and 16 around the sides. Plants would have to be rotated almost every day. Or use a hazy (lazy) susan to place plants on and rotate.
Cree globes use x-te leds

Based of what captain and pet are doing I think it could defiantly do some damage. You know I love xt-e's. I wonder what bin the house bulbs have. But with solid startup(free) I would DIY top bin xt-e's so that there would be no need for refection and pattern perfectly. That's the only weak point...but your vertical idea makes it work.

Thanks Brother Tags I Knew Where You Were Heading.I Also Think My Goal Could The Into The Norm.In My Dream 4x8 Tent I Know I Would Blow Away A 1000 HPS And Give The 2000 Watt A Run For Its Money.Now The Only Setup That Would make Me Nervous Is The BadAss 860 Watt CMH,Thats 1 Bitchen Bulb

What about the "biofeedback programmable system"

the globes have these

I'd kinda like to see the spectral analysis on those Cree bulbs. Just out of curiosity, really, the results speak for themselves.

click on the PDF link and scroll down. In my last post, right above yours.

Warm White 2600K-3700K
Q4 100 Flux (lm) @ 85 °C
Q5 107 Flux (lm) @ 85 °C

The SPD graph in the PDF? It's just an average, there are different bins. I'd like to know if Cree even distinguish a bin for their line of bulbs, or if they just use whatever. I'd be interested to see the actual SPD graph of a Cree Warm White, perhaps even with/without the globe just for the heck of it.

^^^^ if you look at the x-pg spd graph (PDF) it differs from the x-te. You know how Kelvin works.....

How many of each and in what configuration...how many watts total??

I got some samples from sink pad and a few are copper. Someone else brought up sink pads...are they good?

A red dominant light with some blue and white for added spectrum coverage. If it's free I'd build a 1000W beast

Copper MCPCB's without a dialectric(=isolating) layer are worth it! Some LED's depend on good thermal transfer, e.g. red XP-E:



As you can see they loose flux quickly with rising temperature and that's why they benefit from superior cooling (copper pads).

If going with a company I would do (2) AT660's with my indagro pontoon hanging in the middle.


And my DIY design would be 48" bars with 24 xt-e's on each bar driven at 700mA with 60*lens. That's ≈50w/bar, and I would use 12-14 bars per 4x4. I would do 65WW:35CW.

What I have now (2 SolarStorm 800w CLW) but with 2 300 Plasmas angled down from the corners in each 4x4 area heh.. I might actually do that after next harvest
