I think we're in agreement of how they arrive at 1w, 2w, 3w rating. However, the key info here is that these are just 1w that are being overdriven as far as the cooling reliably allows. TRUE 3w exist, however I don't believe there are grow lights using them today, they are much too expensive. Maybe those growbars that are "about to hit market at very high price" over in the other thread use them and overdrive them even higher?

yeah i hear you. the part im concerned with is the claims of all the grow journals that use these lower wattage lights getting the results they claim....im happy with what im doing atm but we shall see come weigh in time...anyway NWI sorry for jacking your thread

Don't worry mate, you have hijacked nothing. Discussion is the best way to figure this shit out man.

that dont make sense from what i know about solid state lights...but ill look into it.

there are some 3 watt diodes that use the 1 watt chips in the same bulb to achive that rating. a true 3 watt die only has 1 chip. as for over clocking a one watt diode by 3 times to get a 3 watt rating? pretty sure it wouldnt work or would burn out in a very short period of time.

and 1 watt chips are a dime a dozen so im sure every light manufacturer would just riddle their products in them...and claim even higher wattages.

I'll post some more pics later, wanna just relax right now, i potted another 18 autos in air pots and soil and chucked em under the LED.

where'd you buy your LED?

anyone seen/heard of these guys... http://www.futureledgrowthtechnology.com/ ?

fukken £750 argh i need prooooooof

I doubt its worth it if they're still using 1w diode. While 1w is the best as far as efficiency when converting power to useable plant light, but they do not complete with 2 or 3w diodes as far as penetration (600 1w diode panel <<< 600 3w diode panel). If they were using all 3w diodes I'd consider the price fair, but they're not so I doubt its a good deal. Its also better in the opinions of many to have more smaller watt panels than fewer bigger ones (unless you plan on using light movers). I also can't find any info on the lens angle used, but they get props for giving any kind of PAR rating

For the price of one of those I'd rather get a6 '240w' Blackstar (840w) or 3 GLH 180s (740w). Either way you would be getting it in 3w diodes instead of 1w, and would have a greater distribution of the lights with more control (use fewer panels or more, raise and lower each to its plant, etc etc) You could still get that expensive panel, it will work good (but you will probably be stuck having to SCROG or LST since the penetration factor will be lower)

this is their reasoning... don't know what to believe anymore lolz

WHICH LED TO USE? 1W, 2W OR 3W?
Knowing the LED wattage is importantMany, many companies are using 2W, 3W, 5W, 6W or even higher wattage LEDs and claiming that they are more powerful and productive during flowering.
There is no more efficient LED than the High-Intensity 1W 10mm DiodeThe reason being is the input vs. output ratio drops off dramatically the higher wattage LED that is used. The way you know this to be true is to test your light with a voltage meter to see the actual power consumption of your light.
Our units are fitted with 1W 10mm DiodesThey draw 95%+ of declared light wattage depending on temperature, whereas a unit comprised of all 3W Diodes will draw between 70-75% of declared power consumption.
It may sound good to hear a higher wattage LED being used, but the truth of the matter is that you are actually losing your overall power output by using these inefficient higher-wattage LEDs.

also i think i read somewhere on there that the angle was 110degree but not sure...
as far as penetration i'm going to be running scrog anyway so its not that much of an issue...
the thing is i don't wanna buy some dodgey shit off ebay and have no recourse whatsoever.. at least this guy is online proper registered company and he seems quite chatty - if there's a problem i can find him ask him politely to sort it.. or mash him the fuck up..

Just think, $1500 on a 600 1w LED panel. If one LED dies you could potentially lose hundreds of LEDs and be completely out if you have to turn it in for repairs. Where as with several other companies you could wait longer before having to send it in for a replacement (and get a longer warranty) because they build theirs so only 1 LED can go out at a time. Or you could buy multiple units from another company, and if one needs repairs you still have several others to work with.

JDizzle do ur fans on the blackstar run really loud??Or say louder than a ballast fans..Stealth is key for me but i want 2 or 3 blackstars but im hearing there really loud and it doesnt make sense to me .......

I have a GLH not a blackstar, my GLH has 6 fans that run on 3w I believe and its comparable to a loud Xbox 360 or an average gaming computer (one that isn't super quiet or exactly loud)

"There is no more efficient LED than the High-Intensity 1W 10mm Diode"

See that is where they get people I think, no one is arguing that 3w is more efficient. We are arguing that using a 3w diode run at 1.5-2w produces more light and penetrates further than 1w diodes (or clusters of 1w put together). A panel with 100 3w diodes will always grow better than a panel with 100 1w diodes if they are otherwise equal (in choice of wavelengths, lens angle). So when a panel with 3w diodes is cheaper than a panel with 1w diodes I would go with the 3w (more light and more penetration although technically not as efficient for how much power used). A panel of 600 of the best 1w diodes wouldn't compare to 600 of the upper end 3w diodes being used (although it would still be good for SCROG or LST).

So its louder than my ballast??I have a Xbox havent used in awhiile becuz i kep breaking controllers lol, but i dont remeber it being to loud..Im gonna be in a closet so with the doors shut would i be able to hear it running..Sorry as for alot of people i need stealth to but my 600w is killing me with heat not plants just me lol..Thanks for the help boss and sry for the confusing on the panel u had..

Sorry I think I am confusing people. I don't have a '240w' Blackstar I have a 395w Spectra from growledhydro. I would be worried about keeping it in a closet that people would be around as it is as loud as a computer (not a crazy one full of fans for gaming but not as silent as my nice gaming rig). I am not worried though about it being in my room which is always locked though, from outside you can't really hear it, and with the 190 CFM fan on like I always have it it sounds like there is a computer in my room that is loud enough to hear from outside the bedroom (from the porch 1 story below you can't hear it at all).

I don't know how loud a blackstar '240w' is, but I imagine like all other panels that use fewer than 150w that it would not run as loud as my 395 panel (I don't consider it too noisy) unless they went with fans that were loud (balance of cost and cooling ability)

yeah i want LED for the fact of less heat output i mean the closet is in a room that people dont go in but the bathroom is close by and roomates bedroom as he doesnt know lol...I guess ill call gotham and see how loud they r and other places with smaller units as i want 2, 1 for eitherside of my hps and feel like 2 or 3 smaller panels will give better coverage than 1big1 just my thoughts..

I got all four of the from http://www.accesshydroponic.com/product.php?productid=351&cat=39&page=2 this is all four in a 2x2x4 cabinet and it is bright and they don't produce shit for heat really

Thanks mate, my LED runs extremely quiet, zero issues and most certainly no where near what a fans noise is, even though there are 6 fans.

Sorry dude I forgot to answer you...from these guys.....http://hydroponicshut.com/Pro-Grow-550-Watt-LED-Grow-Light.html

I like that they are selective switch which a lot of others don't have, very well made and has a 3 year warranty with a guarantee to replace your LED with a loaner whilst they fix yours if any issues occur.

The only issue so far I see is what jdizzle brought up, if one LED goes then perhaps a whole strip is not illuminated but I don't know if that is the case, I have not asked them that but you may want to. It may be the case that they do have a bypass of sorts.

He also gave me free shipping to the UK and you may mention my name, it may help both of us as if this unit works in my experiment then I will purchase a further 3x units. PM me for more details if you like.
