On the Samsung LED homepage, you'll find the LED catalog. Maybe that helps 🤔

Would need to know the brand and model of light fixture. If it's your Lazerlite 720w from 1 of your Diaries then they're LM281+ diodes.

Do I need to lower my lights?
Do I need to lower my lights? I'm using a Kingbrite 240W Samsung lm301h and I just went into flowering period. I think the light is a bit overpowered for the room, so I've left it at about 21 inches above the tops of the plant. At this distance, all areas are getting 27k lux.

Light burn or nutrient burn?
Hey guys. The tips of my leaves are starting to turn yellow and I’m wondering if this is a nutrient burn or light burn? I lowered my ppm feeding to about 250 a few days ago and am growing in ocean forest fox farm soil. And the light is an optic 2 running just the cobs at 24”.

Light burn
2 fairly new leaves at top (opposite ends) seem to show signs of light burn (yellow tips). They recently turned a bit more green but the tips are still quite yellow. Light = 13 inches away. PAR 370 at center, 350 on sides. DLI=~ 22.5. CO2 bag in tent (at about 620). Thoughts?

Would this be an upgrade or downgrade?
Currently using a 400w HPS on a 18/6 schedule for my autoflower. I've just seen this being sold on FB and wondered whether this might be as efficient/better/worse than what I already have Appreciate that it's a 'budget' light, but still looks pretty good 🤷♂️🏼

As this strain is an auto, going on 12hr of light during flowering won't do her any harm right ?

Light help please :)
I’m trying to figure out the optimal height to hang my KingLed 1000w full spectrum at for seedling, veg, and flower. I feel like part of why my plant was is so small is due to incorrect hanging of the light but idk
