Yep found my receipt I paid around 70 dollars per/2 pack and they are literally not even wired in anymore. I just have 5 x 2 packs of them sitting in the corner.. Maybe I will daisy chain them above my canopies for generator lighting if power goes out? ¯\_(ツ)_/¯
Well at least one of us didn't buy a shitty product lol.I've just changed the bulbs in my Gt lightwave 4 bulb T5 unit, 4 osram lumilux 6500k cost me £16 delivered.
With old original bulbs @ around a foot was 952 lux after changing the to the new bulbs the reading was up to 1382 lux

Watt for watt 4k led has a much higher output but i get heat from the fluorescents and they're beneficial to my clones at 3 days old.
I have been saying the Gavita 1700e is not a 1:1 replacement for the 1000w HPS and people argue. Gavita website itself says the 1930e is a direct replacement NOT the 1700e..This led community is a bit disgusting and I would have to put the majority on par with the vaccination absolutists who just love mandates and cloth masks.
Op comes in and shares his experience, potentially saving others some cash and hardship when they don't get a 1:1 replacement for their T5 and get's pounced on and treated like he has no clue how to grow plants.
Yet, the fanboys continue to cheer for led mandates of commercial grow ops?
Growers love technology, I just look forward to the day that these led peddling bandits actually offer honest products that will swap 1:1 with the technology they claim to replace without all of the woes.
Wouldn't most agree that traditionally plant cuttings are rooted in shade? Any idea what that spectrum looks like?
Strange times we are living in
T5 & HPS GROWERS SQUAD UP!
T5 for veg and LED for flower can work nicely too
For fun beat them down on price as hard as you can and get a 2 pack of them and see what I"m talking about in real life testing.
The room stays a steady 78-80 °F 60-65% humidity so I don't think environment is the issue. I have Co2 supplementation of 800-1000 PPM and when I grow under the T5s they are explosive. There is no issue to solve, these lights suck.They are getting more light and less heat. Little plants don't enjoy that.

I run my clone & veg 18/6 so they get a dark period. Climate is controlled with a 1 ton mini split with heat pump for if temps drop below 70 at night.
I noticed the clones that were under the LED were taking TWICE the time to root and for the first time in a couple years I had some clones actually fail to root under these further pissing me off. The problem is when these cause the plants to grow weird due to spectrum or lack of power once you transplant them, they have to start their life with that shitty growth, like 4 nodes stacked on top of each other it looked like they were pre-flowering almost..
I have been having pretty good results with 3500K led tubes in T5 fixtures. I would still give the growth performance a better rating under the old 6500K fluorescents though.
The T5 mixed in with LED would likely perform better I'm guessing. The power savings and less heat is the only reason I can see LED being at all interesting anymore. If anything my VEG room is going to be converted to CMH and I'm going to sell the Growers Choice ROI-720 and not use LED at all. If electricity wasn't so expensive everyone I feel like would be running T5 & HID lighting.I have been having pretty good results with 3500K led tubes in T5 fixtures. I would still give the growth performance a better rating under the old 6500K fluorescents though.
I am going to try doing a mix 3:1 LED Tube to Fluorescent and see how that goes.
The power savings is definitely something worth noting if we can get the proper growth performance

Exactly - spectrum
yeah this is no bueno seen from multiple angles. its just heavy on the same depth of the leaf tissue.
Spectrum seems to be the real issue with these lights based on experienced opinions. I swear the plants literally do not laterally grow at all they just stack nodes and it almost looks like pre-flowering with how bad it is. I worked with Luxx customer service to no resolution for a month before making this thread.
