so send me some samples already

correct C better than B better than D B and D cost the same zero reason to use D imo

find out which veros they use (B,C, or D) and i can advise in the differences cree 3590 is pretty much old overpriced tech but has good name recognition so some retailers still sell them, largely to people who arent up to speed on current tech

if youre in US i can match their prices after shipping. if youre not in us they can prob do you better depending on size of order, etc

if you werent too lazy to link and actually posted specs before making 2 dozen posts with no information it wouldnt be a 4 page thread... and here we are and we still dont have the info I guarantee its quicker to find a link than post 20 times arguing with people who literally have no idea...

oh the filament looking bulbs? those have been around for years. if youd link them we wouldnt have to speculate

ive already got several of those. same as all the others

make sure you use bjbs if you want to mount reflectors- the mechas lack the 3rd and 4th hole for the reflectors with ideal holders

sure post a link

im not demanding anything... just letting you know the bar if you want people to consider your info credible

no you can do it with a cheap light meter.but you need SOME metric comparing successive crops with different lights is the definiton of anecdotal evidence, as explained here all the time I think you already did that the 'info' is not at odds with anything ive done i dont like to add...

how bout you just replace your 1000 w bulb with a 400W bulb and $50 ballast and get more lumens than the 36000 lumens that thing has lol blows my mind that snake oil salesmen are still out there.

6@ 60W would do it im not quite sure what you mean by 'single cobs' as pretty much all cobs are "single cobs" again,the larger drivers are more efficient. you'll get the same amount of light for less energy input (or more light for same energy input) the luminus at 60W are pretty efficient...

correct i dont have time to mess with lightbulbs you need to provide results if you'd like my opinion correct. with pretty much any bulb off the shelf at walmart or home depot north of 100 lm/W if theres a difference do some tests and show us. Not gonna take your word for it in absence of any...

yes i 100% think its erroneous to represent that there is some dramatic difference with zero data to back it up. get 2 similar wattage bulbs and show us a controlled test with a par meter and a wattsup and we'll talk. i would be literally shocked if there is more than a 10-15% difference between...

example? i never put down chips that have actual specs i will never put that much thought into a $5 lightbulb that might crack 120 lm/W on a good day people who are serious, and actually investing hundreds of dollars in a setup, should be using the best cobs they can get (considering decent...

youre beating 800W with 70W? obviously a typo for my actual garden ive moved on from techs that use less than 150 lm/w awhile ago, i use these for clones/ quarantined plants,/ oddball stuff. my clone tray really doesnt care if the 15W bulb above it is 1400 or 1700 lumens shitty walmart brand...

2700k 1600 lumens 15W year and half ago. https://www.rollitup.org/t/got-my-ge-brightstiks.896869/page-17#post-13495020 where are they at now?

in the time since that thread was made they are basically the same midpowers that increased maybe 5% in efficiency. there were 1700 lm 15W bulbs 2 years ago, what are that at now? A slight efficiency bump really doesnt invalidate anything in that thread at all.

HBG-60-1050 = 90% efficient hlg600-48A = 96% efficient, dimmable, cheaper per watt, remote mountable, less wiring, etc etc
