Does Australia have magic J series 3030's? 195lpw from the jk3030?? Not seeing that anywhere, in person or specs. Even at the cold start min output, they aren't hitting those numbers.

Why not grab some H-influx strips over F strips if F's are getting price gouged so much right now? Can push the 301b's or the 561c's pretty good and still get better efficiency than a J series chip ran softer.

Hello guys !

A lil' question, is it alright to run some lm561c 288QB at 0.5A 24w without heatsink ?
I guess it is but wanted to check with some experienced users

Okay, boyz 'n gals! It's time to present my current light cause it's ready to use!
I first thought I should create an own thread but decided against. I can not show any plants anyway so this thread is the best place. If anyone have questions feel free to ask what you want.
It consists of 20x 2ft. F-Series strips/3000°K/CRI80 in 10s2p to one HLG-240H-C1050B and 8x Blux V18c COB's in 3000°K/CRI90 to a HLG-120H-C500B, approximately 400w net., 440w total.View attachment 4111187 View attachment 4111188 View attachment 4111189 View attachment 4111190 View attachment 4111191 View attachment 4111192 View attachment 4111193 View attachment 4111198 Than I've added a 39w UV-A/B reptile T5HO tube and a 730nm Flower-Trigger, consisting of 6x Cree XP-E's on a 5w driver. Main light, UVB tube and flower trigger are all connected via Sonoff timers and controlled via ewelink app. Currently I run some stability tests and if all works as expected I will sell it to a friend who's already waiting.

A mix of 3k and 3.5k works for me.
Not enough strips for a 240h24B driver. Somewhere between 9-12 strips from my experience.
My example, 9 f-series strips ran by a HLG240H24B.

If you want to run 6 stripes than a LPV-150-24 would be my choice of driver. Not dimable and not as efficient as a HLG but for a 2x2 that would be my choice.

I guess I'm a moron because when I use the search function I only come up with a couple of things.

Are those the same strain? Looks like under the "blurple" array the buds have way less leaf, or way less trimming to do..

Different cultivars and the left is 2 weeks behind the right.

ChiefRunningPhist said:

The left looks further along. I guess being different cultivars probably makes up for that. Good looking plants

Does the light on the right have the deep reds and uv also? On a switch?

With all do respect. If you're going to buy a new light. Have you considered that maybe you think these lights you have here are doing a good job only because you've never tried anything else? I say this only to help you out, for real!
If you switch to white light now & not add anymore of those, you may get lucky & be able to mix them together for a decent enhanced spectrum & not feel like the burples were a total waste.
Because I can pretty much assure you (select burple quality comp. are good) that you will be much happier using white or a mixed (burple n white) And so will your plants.
I tried both side by side & the white light did 2/3's better.

Hey guys. I need some advice. I'm about to blow a decent sized wad on a "Fatty VS" from timber, 1300 dollars to be exact for a 5×5×8 tent. I've had people tell me that" DIY Quantum boards" are the way to go because they can be better personalized for my tent. IDK, I've done quite a bit of research on lights lately and the fatty feels right. I just want a good powerful grow light that save me more money than my HID alternatives. Thanks for any help

I prefer COB’s, to quantum boards, and I’ve used both.
