This has been something I've noted, that companies, such as GoGreenLED, will price their products at inflated costs but then offer ridiculous discounts to make up and better match their competitors in prices. It's most definitely a scheme. Can you imagine if someone came to you and said "hey, this company is offering me a 20% discount, will you match them?". You could always raise your prices 50% and then offer a 50% discount, lol, make the customer feel like they were taken care....Most people ask and I would like to offer discounts, but I would need to raise my prices to do so
I have actually considered doing that. Not seriously, but it has crossed my mind. I was talking to someone planing a light scheme a couple weeks ago and they were considering my lamps or another brand. The difference in cost for the same amount of light from the competition was $500 more. IOW, the other brand could offer a $500 discount and match my price.
The PAR values stood out to me as distracting. I was looking for the coverage of a light (or, which light worked best in the OP's space). If I go to an Area-51 page I quickly see 20x20" is optimal in flower. When I visited a Tasty product page, I saw 5-6 different footprints (both square and seriously rectangular. T2-2100, for example). I don't get an immediate sense of "how will this light work in this space. Its optimal coverage." It's like scientific data (useful, but secondary to the very specific and *common* data point I sought).If I ever sell on Amazon/Ebay I might simplify, but the tools on the main page aren't that difficult to understand,
do you mean rman is rhaz?Who put you up to this?
Thanks for explaining that. My intention was to make it easy to view the effects of 10 different lamps in one area, select the grow space and see the resulting light levels on a scale of 0 - 1500 with a target range of 300-1300. I don't disagree with your point of view though.The PAR values stood out to me as distracting. I was looking for the coverage of a light (or, which light worked best in the OP's space).

I'm glad I was helpful. I'm not sure we're talking about the same thing. I was referring to this information in a typical product's page:Thanks for explaining that.

You did make it easy. I'm still a student at this but I've learned the values of PPFD for a given footprint. I have 2 tents in 2x4 and 3x3 sizes and the info given was very helpful.Thanks for explaining that.

I like Pickles suggestion, going to play around with the principal and see what I can come up with.
We do agree on some things then, but you make the point that, for instance with a T2 there is both a PPFD for it's natural footprint of a rectangle but also of a square. Not sure how many have played with light levels from various multi cob lamps but most light sources are ultimately circles. Part of the reason for going with long shrouds was to combat this reality and create lights that could be hung low with the cobs spread out. The T2 does not have much effect on the circle phenomena so is still a good contender for a 2x2 tent, just with the light intensity split up by 12 inches. There's a small reflective penalty but also a small advantage to canopy distance so it kinda evens out. If a person would spend a few minutes digging the main page they would know that that lamp in a 2x2 or or 1.5x2.5 is pretty "bad ass" and that it would be "sufficient" in a 2x3 and that 2 of them in a 3x3 would be better than average. I appreciate the comments because there are several philosophies that kinda clash and it's difficult to provide concise information that satisfies both the momentary glance and the curious number cruncher.I'm glad I was helpful. I'm not sure we're talking about the same thing. I was referring to this information in a typical product's page:
Space usage and light intensity in flowering mode (includes lens loss):
24" x 24" 950 PPFD
18" x 30" 1015 PPFD
24" x 36" 635 PPFD
36" x 36" 850 PPFD
That's where I got stuck. I was looking for something like "Optimal coverage in flower: 24x30." I didn't know how to interpret the above information which covers 4 to 9 sq ft. It didn't seem as specific as I was looking for (as a guideline).
Sidenote: I noticed that I reached a "products" page[1] at one time. I must have got to it from a google search and it's in my URL history. Anyway, I just noticed there's no way to get to that from any link on the page. There are just links to different model types. The overall list of products was nice because, well... (it just comes to mind now) there's no information on the individual product pages indicating why they are segregated into models like that. So, instead of clicking into 3 different areas, one product page was/is nice to see it all at once.
Regarding the coverage info I was looking for (and your desire to provide details), a PAR grid would be a nice visual representation of the coverage -- and provide details about it. Two or three could be created for minimum, maximum (optimal?) footprint?
That would be good info and also elegantly convey the data point I was looking for.

Thank you.You did make it easy. I'm still a student at this but I've learned the values of PPFD for a given footprint. I have 2 tents in 2x4 and 3x3 sizes and the info given was very helpful.
The wattage confusion in the led industry reminds me of the claims of audio amps/receivers back around 1970, when we learned the difference between peak and RMS watts and the tricks used by manufacturers.

Sorry. I had a feeling I was going to trigger a reaction like that.but you make the point that, for instance with a T2 there is both a PPFD for it's natural footprint of a rectangle but also of a square...
In my defense,
IMO you have great site. Plenty of info to make a choice...but not to windy! And you are one the few cob vendors selling bars over boxes. Bars are better for the small grower wanting a good spread...from my experience.Well, don't be sorry. Being here as much as you are I suspect you appreciate the nerdy aspects of building lights. I do agree that light slinging requires a fine finesse to provide the user with the optimal solutions on the fly, but I don't know exactly what that is. We can talk about optimal PPFD, and what exactly should be the "recommended" footprint, what should be a "super" footprint, what should be a "high efficiency" flowering solution, and what are min/max veg solutions because those are different based on whether the chamber is dedicated veg or full cycle.
The "coverage" IS the ppfd, density in space. As per the main page, 600w hid single ended with reflective losses is about 650 PPFD in a 4x4. This is the reference information that makes the two graphics on my main page relevant to light intensity expectations to A- someone who has used HID and B- someone who hasn't used HID but aspires to it from whatever other low efficiency solution they are accustomed too. Prior to the induction of LED COB technology the best solution for a 2x2 might have been a 250w HPS. or a 3x3 or 2x4, a 400w HPS, and then 600s and 1000s in 4x4s and 5x5s, or 1800 in a 4x8, 3000s in a 5x10, etc. I like the idea of footprints, but it's an idea I've considered over time, rather than information I can give out. You bring up my own internal arguments over the last 6 months or so. On a personal level I want nothing to do with "claims" outside my own estimations of lamp performance on a technical level.
I agree there needs to be a reasonable footprint but I'm undecided when it comes to what that is exactly, so I provide the technical information. I try to, and have the luxury of, building great lamps, but dealing with the recommended space is a philosophical question which I can only chime in on, though I acknowledge a standard would be nice. I think a par-watt rating would be the simplest and most reasonably accurate comparison between brands (which I offer on the product pages).
But I could use some help in that regard which is why I appreciate the criticism. I think a simple par-watt rating is the best way to facilitate momentary comparisons but I'm open to suggestions on how to make various types of space data more immediately accessible, and agree that in certain contexts marketing aspects of one kind hold prominence over another. If you can, on second glance, make sense of my main page, then thanks and I salute you. Complicated is good sometimes and I am just a humble lamp maker who has a reasonable understanding of the components involved and want's to provide good solutions for the new to serious hobby growers, as well as push the interest in high efficiency led solutions. Being "all" business like about it comes in second because I don't have the patience for the whole taco. I look forward to a time when I can focus on building lamps more quickly rather than marketing them more efficently if that gives you an idea of my attitude towards it. I don't think I am the best at everything, but I have no choice at this point in this venture.
Rahz,
For a 2' x 4' x 7' tall tent with 2 plants would you recommend two T2-1750 or one T4-1750 or something else and why?
What is the difference between reflector and lenses?
Thanks. I joined this site just to ask you these questions.
The T4-1750 would be the same amount of light as 2 T2-1750s, so no reason to spend the extra on two smaller lamps if it's going in a 2x4.Rahz,
