Thanx Pat
How bout bulb replacement ?

[pfolight1]

My guess is when the life of the LED's are up you will throw the fixture away and replace it. I currently do that with my old computers. If that isn't the case then we will develop a plan to handle led replacement. If there is a premature failure the LED circuit boards have been designed to be replaceable in the field.

We currently do not sell the LED boards by themselves. We are afraid of people not cooling the LED's enough. This is one of the many reasons why the DIY people have had difficulty making high light output LED fixtures last over their last two to three years of trying.

I see that the preliminary price of $1500 for a 48" fixture jumped to $2400. Does the expected payback period on energy savings and bulb replacement now jump from three years to 5? I suspect that this technology will be like LCD TV’s. These guys have the jump on everyone so can afford to charge crazy prices. Wait a few years and the price will be compatible to current fixtures while still having the benefit of cooling and energy savings.

Personally, I'm sick of new technology that’s supposed to revolutionize our lives and last longer, be more eco friendly...Yada, yada..... Everything you buy that's supposed to save you money.....COST ALOT MORE TO BUY...therefore negating the cost savings. When I bought a new Energy efficient AC unit for my house, the more efficient, the more expensive...payback was 10-15 years. New Hybrid vehicles that get 60 MPG...COST $4K more than conventional.... average of 7 year payback when most people keep cars only 4 years. Even longer life lithium batteries....Double the price of standard energizers. There aint no such thing as a free lunch. I say wait a few years till the patent runs out and the competition and greed for the market share will bring the prices down.

I don't blame the guy for Jacking the prices up...Supply and demand is what it's is, but as always, getting one of these now means that you'll be paying the high price to be the "First One" on your block to have the cool new stuff. Sometimes it's cool to be that guy, but it gets expensive after awhile. I'm sure I'll make the swap someday. But I'm just now considering a LCD TV.....Now that they aren't killing us on the prices.

Uh-huh. Remember last Tuesday when I forgot my money...you paid

48" 20K Solaris LED Illumination System. Supplied with Control Modular and Mounting Feet. Solaris-G-48-20K $2325

Thats a big increase from the $1400 that was originally on the site, I wonder if they doubled the benefit of the already designed light before they doubled the price.

Well if you do the math it is not really a bad deal.

if you run your lights 12hrs a day 365days a year these LED will last more than 11years

If I run my T5's that long i would spend:
$500 fixture
$3500 bulb replacement (8 bulbs every 6 months $20@ for 11 years.)
that doesnt include ballasts and fans and anything else that might wear out or electrical savings, lack of chiller, fans, timers.

Not to mention the built in ability to control the lighting spectrum much more realistically.

I think I am sold even at this price

That does not mean that I would not rather pay less though. (Hint Hint)

[KMP]

once you make that plunge you can never give up this hobby

[Witfull]

the one thing i dont care for,,,,tey state its the equivalent of a 250wt 20k bulb. personally, 20k's dont do it for me. they are way too blue and have weak PAR.

[Stalwart]

I think the colors are adjustable.

"The light can be adjusted from 6.5K to 22K, or anywhere in between, to set the ideal color temperature"

[boozeman]

from 1,400 to 2,300... ''foggetaboutit''!!!

[Witfull]

true,,,but the more you turn the blue (not true actinic) bulbs down, your losing even more par than gaining.

Guess I will be sticking with the Sfiligoi MH pendants I have on my wishlist

[corallimorph]

Recived my three Solaris units today for new culture systems at the home lab.............unbelievable....will post pics as soon as i can close my mouth.

i saw these PFO lights at MACNA, my biggest complaint is they don't do deep tank like 24"+ and they are too blue... but the future will be in LEDs, just not yet...
