Anything I should take into consideration before ordering 2 x KingBrite 240W qb288 v3 lm301h red mix UV IR?

Been researching lights for a good few weeks, for my application and budget decided on the KingBrite 240W qb288 v3 lm301h red mix UV IR.

My only concern is that supposedly the Epistar LED's lose their efficiency quickly? Or is it not really something to worry about?
(Just wondering about the Epistar issue and anything else that I might not have taken into consideration, before I pull the trigger. Any feedback?)

I'm set on Kingbrite, just wondering if this is the best option from them.


[About my grow]:

What: Landrace Equatorial Sativas (planning to run two of the 4000K models above, as equatorial landraces seem to favor higher K's)
Why: Growing for effect and personal use. Don't mind small yield at all (I know most recommend 3000K or 3500K for yield).
Where: Ventilated Bathroom: 5.9" x 2.62" - 15.5 sq ft (I already have 1 x 100W Mars LED and 1 x 50W Chinese COB)... So total would be 630W

Do you really want to use ir with those genetics? Id be worried about stretch. Uva could help reduce it though. It's there a model with just uv and no ir?

I've been looking at kingbrite, have you ordered before ? Or know others that have ? I really like the look of their various strips, they use the strips they sell in some of their lights with same heatsink. All different sizes and wattage and diodes come to think of it ! I'm thinking of making me some real nice lights using their strips and maybe some boards but not quite at designing stage yet as barely past general idea ! The strips though seem fantastic when light spread is really took into account ?!?

Never really thought about the red and uv diodes as long as they run at the same wattage etc but now you mention it I'll look into that ! I was thinking of using separate far reds and uv to run separately alongside the lm301h strips but that's just me ! Or not lol

That one does look interesting. You think it's better just looking at the PPFD, or for other reasons as well?

I think the diodes are better quality, they should last longer and operate more efficiently. I’m a layperson, but PPFD, coverage and brand all matter. Have you looked at the bars? They offer better distribution than boards.

I have but for space and logistics reasons wanted to go with something more compact.

But you're right, that one you linked to, the PPFD map does look a lot stronger on the 0.5m test.

Check this one out, the spectrum curve looks closer to sunlight, could also be a great option. I'm asking the rep for the PPFD map and whether they offer it in 4000K.

Also, do you know how much the waterproofing weakens the light? I think I remember it being just like a 1-2% drop in efficiency, but can't remember. I grow in my bathroom so I wanted to get it just in case there's a pipe burst or anything from the sink.
