Lighting TOPled The Manual.

The wait will be worth it though man, I just got done growing with a Reflector series and got great results so you should be very happy.

Oh yes like one of my fav German rappers always says .... i dont have a proplem with weed i only hate waiting on it..... same i feel with that Led right now Bilbo. Common Fed Ex yoe really want to deliver it today Looooool

I Know the feeling! I'm waiting on a new one for the cab i'm building. Checked the tracking about 8 times yesterday....lol!

lol same for me mine is sitting already in my country few hundred kilometers away from me but status stopped there but till 18:00 over here i can pray that it arrives today...... would be awesome as i anyways wanted to pot the lil blueberry auto later so i could do all the work with installing the light n repotting all in one strike.

Got mine a couple days ago. Its also from TOPLED. I believe that many of the resellers on ebay are topled resellers. My 2, three hundred watt units are working well.

I've got to firmly disagree here with your recommendation. Those lux levels you recommended may be great for more traditional light sources like HID, but when talking LEDs, PAR is the name of the game. I don't mean to speak as if you didn't know this or what I'm about to explain already, but it may be useful for those new to LED light sources. Lumen/lux only applies to applications where human vision is concerned. We can still use lux if we know our light source's spectrum. This is why such recommendations exist for HID light systems for indoor gardening. As humans, we are much more perceptive to light in the green spectrum. Here's an example: 3 light sources, all being driven at the same output level or wattage. 3 colors: red, green, and blue. Our eyes would perceive the green source as "brightest." That's just how human sight has developed. Our usual tools like lumen and lux measurements therefore are also more sensitive to green light. Plants are practically the opposite. Green light is hardly used by plants. You could try to use the green light from the example to grow a plant based on its higher lux rating, but it wont do much without the reds/blues that a plant needs. So it gets even rougher when you consider how spectrums from various LED panels differ. There are models for veg, bloom, full spectrum, plus each company's own little twist like diodes in white, IR, and UV flavors. Even if all their PAR readings were the same, their lumen/lux readings could vary wildly. Therefore, it's nearly impossible to recommend adequate light levels in lux from an LED source. However, you can still use lux readings to get a general feel for the RELATIVE light intensities at different heights/locations/orientations in the grow space. So while the numbers mean practically NOTHING to plants at face value, it allows the grower to compare the values proportionally. Doing so may help to see how their LED lense angles perform, or how their reflective surfaces behave. Maybe you'll even find a hotspot. A hot spot's lux number may not be all that high, but if it's proportionally much higher than other readings in a similar area, you'll know.

Though while what you say is true, it seems your forgetting that your actual measuring LUX within the spectrum provided by the grow light, which has little or no green and white. So, IMO your measurements are more meaningful than you think. the 42,000 lux light density point id where these lights are at or near the max pontential of the plants ability to absorb and use. I just had to make a new light hanger for my TopLEd 300 watt standard unit to get more height. it was at about 12" above the tallest plant. I had just placed that plant in there yesterdAY, and in less than 12 hours, I was seeing sighs of light bleaching. I managed to raise the light another 8" so all is well now. Going to have to bend her if she stretches more, she's already 44" tall ( 56" with the depth of the pot ).

Dr. You think a 300w Unit is Proper Enought to catch Max Production in my 2x2 tent ?

The 300 watt is more than enough for a 2x2! I have a pair of 300watt units and they are covering a 4'x5' area easily. ( they are quite high up to do that but my plants average 40" tall )

Could you please put a photo up pop of the bleaching so i could see what to look out for if that ok "AFN smoke out"

Do you UK growers check UK ebay for these items? you may save a lot of money buying from a reseller. I got my pair of 300 watt units for $242 shipped in May, and the same seller has them now for $205 U.S. shipped a pair! I just bought a TopLEd Mars II 180 watt UFO for $74 U.S. shipped. I know they have resellers with UK warehouses.

Does bleaching effect the plant except its appearance? I have that going on but looks kind of cool.
