HEY LED PEOPLE...... just a quetion probly not a good one but this led panel on amazon is pretty cheap and i was just looking for something to supplement a bush i have under a HID without adding heat. its uh 13.8 watts. 225 bulb 12"x12" thanks for an answer sorry to "BUD" in haha

oh any its a in flowering about 1 month now.. along with 11 8" tall clones about 2 weeks in all under 1x 400whps i wanted to put the LED right above the bush if it would make any differnce or if i should just add cfl's -pf-

Hey guys, i want to start expermenting with LED. What is the BEST LEDs out right now?

I don't own LEDs yet but, I'm going to make my purchase this weekend. a lot of talk about spectra, isis, blackstar, kessil(be careful, a lot of people say it has some problems. but the ones that work, work well) .

read pages 1-260. seems like a lot of reading but its very useful and entertaining lol

Ive managed to hang my custom made led lights today, there from the UK guy on ebay and there mega bright. Firstly my 140 watt veg light

Here is a couple of pics of my 2 x 140 watt main lights for flowering. They give off less colour than the veg light but believe me there super bright. Ill def need some grade 4 sunglasses for these as my eyes are killing me. They are 140 watt actual draw each.

Hello! Nice thread you got going here:) Lots of good information for a newbie in leds..

I am planning to build a small micro box for scrog. I want to go for a led because of their lifespan and limited heat.

Problem is, my box can only be about 50-60cm x 70cm x 70cm (W x L x H)
in inches that will be 23" x 27" x 27".

I will use at least 12 inches in length for my fan setup, so that leaves me with about 15" (38 cm) with room for a led panel.

I was first thinking about a 63w Penetrator Pro, but after reading this thread I have been looking at at Spectra 120, which now is a Spectra 180w 2011.

Would i manage to run this LED panel in my box or should I stick with Penetrator Pro 63w?

Or should I consider the ISIS-1? I could not find any information about the size of the panel on their site. If you know this please help me out:)

I think I can manage the size for the Spectra 180, but I don't know if its overkill in this box and if can use it with my limited height?

I hope you can help me with the choice, but these 3 seems like to be my best alternatives.

Best regards

EDIT: I also see some people recommend the kessils, they are small and will fit well in my space I guess but I havent seen any successfull grows with it. Maybe they are the way to go when the Halo comes out.

Just starting my third ever grow. My light is a 270w Enhanced Spectrum Supernova LED. So far I have two auto grows and have switched to regular strains(LSD$BlueMystic) and coco and canna nutrients along with hammerhead for pk and atami bloombastic. So far this light has performed as I hoped it would! Curious to see how it performs on this grow. Both seeds are popping thru the coco as of this morning.

i wouldnt buy kessil if theyre having problems pus 30 something watts for almost 300 bucks typical sale price i could get a 135w with more coverage and prolly equal penetration from ecogroled for 310 4 times power nearly same price price per watt is one of the ultimate deciding fators

MK BS 240 first cutting of some small nugs just some frosty Bud PORN Enjoy. I thought I would start harvesting a small amount weekly so I have some way to gage harvest times for this strain in the future. I already know about the punch this delivers after two tokes and I have tried 4 which I did not enjoy as it put me down for the count on a earlier test. These will go into cure for at least two months before they are distributed to some lucky ones. LOL

Did they have any explanation for why you've gotten multiple malfunctioning Kessils?

FUCK this shit! Read para 3 of this article where as nice as they try and sugarcoat this technology the fact is that they acknowledge the shortcomings of series arrays where one bad LED lamp knocks out 5-10 lamps in that series and that's considered SUCCESSFUL!

In this article it is acknowledged by the LED industry that of all the LED lamps mfg at the factory only 30% are considered worthy to be sold since 70% made new at the factory fail to deliver to their own specifications BEFORE THEY LEAVE THE FACTORY. Most growers already know what happens to the 30% they do deem worthy of sale right? They are completely problem free.

http://ecmweb.com/lighting/led-basics-20101001/

For those of you 'old enough' can you remember the old XMAS tree string of lights that you had to go through every lamp to find the bad one and replace it to make the string come back on? That's the same problem with an LED power supply which will service 5-10 LED lamps and a single LED lamp burning out in that array will knock the other lamps out.

So when factoring a high power 3 watt LED lamp it takes 2 volts to power that lamp so if the power supply (Kessils) is rated @ 20 volts then it's likely that 5-10 lamps would be affected by a single LED failure.

It's bad enough we are now forced to choose between LED and CFL for our replacement lamps because of their greater energy efficiencies and our greener footprint for our planet since incandescent lamps will be illegal to sell in the USA as of 2014 but as growers this can cost a fortune in crop loss and lower yields while we wait for a mfg to make it right.

Yes I'm pissed off because I wasted time and money but I'll get over it. Thanks for letting me vent now where's my bong.

The GLH Spectras won't go down if one light burns out. I think the Magnums have this safety feature too. Don't know about Blackstars.

The LED mfg's continue to 'paint the technology' to make the latest and greatest product available on the market! At the end of the day if does not deliver yields from full spectrums wavelengths and/or burns up well before it's time it's a circle jerk.

There are three LED power configurations; 1-Series, 2-Parallel or 3- Matrix which is a hybrid of a series/parallel circuit.

Any series wired circuit that has an open circuit such as a single LED lamp burning out will drop out every lamp on that array. There's no getting around that even when they wire the LED arrays in a hybrid series/parallel matrix to avoid all of the lamps being affected by a single failure the resultant current increase overdrives the remaining lamps that work and they too fail in premature succession. Matrix wired arrays delay the inevitable. The term used is a 'cascading failure' of the entire lamp.

Lastly if we are to straight parallel wire LED lamps then a single 2 volt 3 watt LED lamp bundled into a single fixture of 160 LED lamps for a total of 500 watts would then consume approximately 200 amps of current to run a single fixture. This solution would require you to use two separate 3/0 cu wire to feed the single fixture that is roughly a 1" (x2) diameter copper wire. That's probably more current then comes into your whole house at the service entrance.

I think not...there are better options and life is to short to risk even a single grow
