I believe this writeup from Icemud explains everything a light buyer should know
That was incredibly informative and easy to read! Thanks for sharing that! Just finished reading every post on this thread
As a new grower aiming to become a mass supplier someday, I'm loving the experience and knowledge! I can't wait to order me 4 80s or 1 320 for my grow tent! Currently I use 2x vipaspec 600 and the 18' hanging heights result in 520ish umols and absolute garbage low values even just a foot or 2 away. Can't wait! I wish they were like $500 or 550 even but I hear quality is great.
I've been struggling over 320 pro vs. 1600. This is what I understand so far, correct me if I'm wrong!
1600 pros:
* wider umol coverage (not a huge difference directly below but definitely better umols further out)
* nearly $200 cheaper
* blue/red spectrum are close to equal and are very fair spectrum levels.
1600 cons:
* Harder to part replacement (soldering)
* no reflectors
* has a glass cover or something? This makes heat dissipation a bit worse.
* lower quality less efficient hardware all around.
* pulls 632 watts vs 320 at 740.
Pro 320 pros:
* Reflectors for a bit higher umols directly under and to the sides, definitely more beneficial in a 4x4 tent.
* Modular inspired part replacement (No soldering)
* pulls more overall watts vs 1600. A little over 100 additional watts I believe
* Higher quality hardware all around.
* Better heat dissipation
Pro 320 cons:
* Less spread past 4x4 in umols vs 1600
* Veg spectrum is lower than red and lower than 1600
That's all I can think of so far. Both come off to me as great lights. Please let me know your opinions!
