mark did i read somewhere you are about to update the solskin 3 channel strips to a new design?, if so any details on what you have planned and when they might be ready for purchase?.

That's why they started incorporating reds and blues, uvs and ir diodes evenly to the boards!!!

Its one of multiple lights, when stacked out the UVA are not actually on the edges, with the exception of the first and last

And even so, turn those edge fixtures all 90° and you're golden.

I dont understand why there are multiple x3 bar + x5 bar units claimih the same efficiency yet are significantly different wattages?

ChilLED Growcraft Commercial LED Grow Lights are available in a wide range of sizes, from a single 20in bar light with 65 watts of power to all the way up to a 40in 6-bar grow light with 1,000 watts of power. Growcraft lights are also available in DIY parts kits which offer substantial savings...

I'm seeing three variables listed, for wattage range, led efficiency and system efficiency. With only minor differences between model, which is as it should be. I don't see PPFD, only PPF. What do you see? Or am I missing the point?I dont understand why there are multiple x3 bar + x5 bar units claimih the same efficiency yet are significantly different wattages?

Mate, there's never been any doubt that photons > spectrum because number of photons are what drive photosynthesis. However, not all photons are equal when it comes to the amount of energy needed to produce them, as well as the photomorphogenic response they trigger in plants.
Red photons are cheaper (in terms of energy) to produce than green and blue, and there are plenty of experiments out there proving it is the more efficient driver of photosynthesis. But plants need more than just red light, so that's where everyone is looking for the balance between red, blue, green, far red and by all accounts UV too – or at least near-UV not found in standard blue-pump LEDs.
The only thing that's really lacking are the number of experiments carried out on cannabis plants to determine the best flowering spectrum – because, let's face it, that's the important phase of growth – and to what extent some parts of the spectrum can stress the plant into producing secondary metabolites that are desirable to medicinal growers. The real issue is that not all plants have the same photomorphogenic response, because many evolved in different environments – and that includes different species of cannabis plants. So really, the "Holy Grail" is to discover which equal number of photons, in whatever spectrum, produce the best desired results with the least amount of electrical energy. You can't just throw any old light at a plant and hope photons trump spectra because at the extreme end, bombarding a plant with green photons and no red or blue can actually end up killing it!
Photons ain't photons mate

yeah for sure, dude. i get that, and i get UV. i still think this -

I agree. There are those cultivars that show more pronounced behaviour standing apart from the pack, when under the same light. I guess some don't mind mono-cropping. But some adjustment of spectrum could be useful for dialing in and finding out what suits some little darlings. No perfect single light out there, but the list of good ones is getting refined. We don't have to go "Big Ag" and demand conformity and uniformity from our plants(subjects). Although it does look good, in photos.Mate, there's never been any doubt that photons > spectrum because number of photons are what drive photosynthesis.

Well I look at it this way: Formula 1 racing is arguably the top echelon of motorsport and each manufacturer is bound by the same engine limitations. But small improvements, when compounded, can make all the difference by the end of the straight – even amongst engines of the same size and configuration.yeah for sure, dude. i get that, and i get UV. i still think this -

One thing is certain, they're not all racing Model Ts – if spectral energy were of no concern, we'd all be growing under tungsten bulbs (CRI 100 anyone?). As someone who has, as a young and stupid grower, tried growing under tungsten bulbs many years ago, I can tell you that all that energy wasted on far red and infrared light grew the tallest, spindliest plants I'm ever likely to admit to growing.
Mate, I get what you're saying. But by the same token, I don't think we should all rest under the knowledge that photons are like cubic inches and you can never get enough. There are limits, and there are more efficient ways of using those photons (as well as more efficient photons that can be used).

its hard to argue that, prawn. i just think apart from UV, we've got in down.
i'd love for there to be a magic sauce, cause arent we close to peak white led efficiency? saw Greengenes talk about this on a tech talk...i think...?

Both these 600w fixtures have the same efficiency rating yet one has less bars?
Same with the 300w models x2.
See what I'm Saying. Unless there are more diodes per bar?

Hi Grotbags, yes we will move to large leds on the centre channel 3535 ie Cree XPG-3, wider UV range, etc and make some other subtle changes, should be coming out in April, along with Boost Boards
Cheers
Mark

I honestly would say so he the time he was actually banned, there has been an ENORMOUS drop off in Chinese light Shills and people who claim outrageous Shit or go against what we all generally believe to be fact as a forum group.
Personally. I think hed do a lot better here then before.

I was going to build my own, bought from cutter, but after all the bs I had to learn myself and in time wasted, and the new lights that came out, I could buy one for the same price when shipped and everything. No savings. Also no response after many messages isn't exactly pushing me to get from a website of a company which I know nothing about. So now I'm into this chilled led x5 600w or an hlg 600h. Which is the same price practically when all said and done, and it's practically plug and play. Also doesn't come in 2 foot strips without heatsink, power supply, and the spectrum is what is needed unless you want uv, or more far red. So now I'm here. Which is better. Chilled x5? Or hlg 600? Both only around 700-800 bucks.

HLG 550 is tried and true. But the form factor of strip lights give phenomenal spread. It's a tough
