Most Efficient LED Light

[CobKits]

hey guys

wanted to know what everyone's thoughts are right now on the most Efficient LED available today.

I want to replace several Gavita DE 1000W in our rooms we have 6 per room, we would like to replace and can't seem to decide what is a Suitable alternative.

any suggestions or input would be greatly appreciated.

also one more point.
just about every single cob fixture out there would beat the HPS watt per watt.

however unlike hps, the softer you run an LED the more efficient it is. cob "efficiency sluts" like to run their chips as low as 10-25W each to maximize efficiency at great capital cost

so lets take a $40 cree chip:
you can run it at 100W ($0.40/watt) and match an HPS easily
you can run it at 50W($0.80/W) and increase youre efficiency by ~10-15% over the case above, doubling your chip cost in the process
you can run it at 25W ($1.60/W) and increase your efficiency by another 10% over the 50W setup, again doubling your chip cost

so "the most efficient LED" is by definition "the most expensive LED". as far as chips by various manufacturers their top lines are all within +/-10% on lumens/W at a given wattage, but their pricing may vary by as much as +/- 40%. so most efficient shouldnt be your goal. most economical at a given efficiency should be your goal

so most efficient shouldnt be your goal. most economical at a given efficiency should be your goal

This has been what I've been getting at. Usually, running COBs at less efficient, more powerful amps/wattages, I find to be best in a small setup, because you still aren't paying for more than 100w per plant. and in a small setup, you won't ever have more than a few plants or need more than a few higher-amp lights.

Like so. I could run 4 small plants or 2 closet-large plants for less than 200w per kWh

 

[CobKits]

well every application is different. if joe personal med grower wanted to double his chip cost he would do way better by throwing up another tent and doubling his space

willie warehouse may be under strictly regulated square foot limit and have a $30,000 electric bill. so either increasing yield per SF or reducing kWh per yield are his criteria and doubling chip cost may pay itself back within a year

california lightworks is ul listed and is a white-predominant blurple fixture at a VERY competitive price point ($600 for 400W of osram with great logic control)

It's a 1k swap list ..........still, fair enough, forgot about clw...........do we have bin/watt draw confirmation? $600 for 400w is good depending...................yadayada

 

[PSUAGRO.]

Anyone aware who has CXB3590 5000k in stock or better alternative?

what's the deal with 5000k? is this only being used for veg?



edit........wtf,doublepost?whatever........fucking phone

i dont think well ever know the bin, i would assume they are the 3s4s and 3t4t osrams i dont think the new bins are common yet....

It's not just for veg, check out Dawgs 5000k +670(or was it 760nm?) it's pushing some frost

I use 3500k.

I think Apache Tech also has some kind of IP rating or UL thing...not sure, though. Their AT 600 is supposed to be a swap for a 1000 watt HID. Those have been reported to be great small diode array lights....why they haven't gone to COBs is beyond me...why they haven't lowered their prices on their old technology is beyond me, too...but there ya go!

@CobKits so what is the MOST Expensive LED that you are aware of?

 

[Ben-Ben]

@PSUAGRO. Well i hope 5000k works for veg and flower that would be IDEAL.

If you can get into their test program they're $450 plus shipping. List price is $899 but commonly discounted to $799. Growershouse will discount another 20% occasionally with free shipping. 5 year warranty.

 

[testiclees]

Do you use clw?

 

[CobKits]

for several years yes

@CobKits so what is the MOST Expensive LED that you are aware of?

Like on a per chip basis? im not up to speed on most commercial fixtures but im sure theres some $2000 junk out there

I would love to get into their test program! My 5x5 tent rocks the dank with 600 watt HPS (hortilux enhanced spectrum) + 400 watt MH (Grow Lush). Could one of these LED units replace both of my old school rigs?

 

[CobKits]

400W would have a hard time replacing 1000W

 

[Chunky Stool]

400W would have a hard time replacing 1000W

So it's a 400W equivalent instead of a unit that draws 400 watts?
Makes sense I guess. It would make a great addition to my light mix, but even $450 is pricey in my setup. I'm all about max quality for min cost. It would be nice to have UV built in. I need to replace four lizard UVB bulbs right now -- and that's $60!
