Lighting LED VS. LED (brands)

[Dr Fluff]

I like the look of the Zelion too but as you say the price is through the roof but it is Osram made so I can see why.
Osram make some great diodes.
I also like that the zelion is passively cooled making it silent operation.
The only problem is there are three models, the Grow light, the Grow White & the Sun light
The Grow light and the Grow White are virtually identical when it comes to the red and blue part of the spectrum.
They however differ fro each other in two obvious ways the Grow light will give you that pinky light often associated with led grow lights and the Grow white will give out a white light.
The other difference albeit a more subtle one is the fact that the grow white also has very low levels of green, yellow and orange.
However the blue part of the spectrum is not so powerful in either the Grow light or the Grow white.
This is where the Sun light comes in and it has the blue spectrum on maximum as well as giving out some green, yellow, orange & red.
The Sun lights spectrum trails is most powerful between 425nm & 500nm after that the spectrum starts to trail off.
I would imagine the best grow set up would use a combination of these light adding to the outlay.
Deep pockets needed indeed.
Here I include some spectral graphs to show the difference between the different Osram Zelions.

I think this video is one of the best A B comparisons for a light source.

I was actually going to make a thread about these exact questions I'm sure many new growers or growers looking to upgrade may have. I am not new to grow lights/leds and in the DIY world have built, bought, sold and traded over 500 individual cobs.

This topic is very important and I feel overlooked. Led vs led. Now I have my suggestions but that's not really relevant and also know I do not have any ties to any led company. The most important part about led grow lights are the parts themselves. This is the most covered up area as well. It's like buying a race car and not even knowing what type of engine is in it. Is it a turbocharged Hyundai engine or a fine crafted Italian Lamborghini masterpiece. Most lights available today all use the same LEDs/engines and just dress them up differently. Different reflectors, different frames, different color but an epistsr led only performs so well. Watt for watt an epistar and brigelux led perform worse then hps. If you have 100w of led and not "equivalent" vs 100w of hps the temps in the led room will be higher. Most companies make claims and do not back them because they can't. LEDs have lower wattages and bigger fans so the heat is not noticeable directly but close up your tent and you'll see exactly what I mean. I own epistsr panels and feel they do have their place but I treat them with respect that the 100$ panel deserves. The claims are not real and the heat/ lack of growth is. The difference between a Mars or kind or black dog ext. is advertising, color, shape, wattage and price. They use the same engines. where price skyrockets is when you change the engine. Companies that use osram and Cree are much more expensive and only because the LEDs themselves are more expensive. That's why cobs are so popular. 1 5 watt Cree LED will outperform 2 5watt epistsr. So when you put things into perspective the price is more understandable.

When you decide on jumping into led make sure there is legitimate proof before you fall for any claims. Find out why panels A's epistsr LEDs are more than panel B's LEDs. If you get an answer please fill me in. If you want to buy a 1700$ panel find out why they are 4x the price of a similar wattage panel. Ask what engine is in your race car and take the time to learn which engine is the best. One thing I can tell you is there is nothing stopping a company from saying a 100w panel will beat a 1000w hps. Or there is absolutely no heat when they would turn cherry red if the fan was disconnected. Take the time to learn the lights and don't fall for biased opinions.

Sorry about the sideways shot - not sure what's going on there.

Might I suggest taking a look at todogrowled for decent spec / decent price LEDs.

The 2 you see either side of the HS1 are TGL Star 60s and the plants adore them.

That's crazy you mentioned them. I came up with my own lights awhile back that are very close to these. I put things on hold for about 6 months questioning my path but now think I'm going forward with the builds and sales. Todogrow is great I just think the price is a little high for 3070's

Think they're the closest when it comes to value for money plus they're built like little tanks! [I like little tanks!]

Fantastic additions to the grow tent - though me know nuffin : ]

Would also be v interested to see your product.

Would also be v interested to see your product.

Soon enough. I have them for sale locally and things are moving pretty fast. 50w lights with top efficiency. I'm also working on some massive 150-200w cobs good for a 3x3

@BigSm0 can you drop some pix?

Osram is pretty good, here* is a passive cooled led i think about copping 3 for myselfs little owngrown using osram top bin diodes. Wanted the new GN's but im close to lose my patience to be honest...tuff decision anyways...
