    Quantum Boards Grow

    I feel that. Yeah, without the extender the effective focal length was 640mm, with the extender it became 896mm. Crazy. Needless to say I didn't use the extender much. I'm using all-white components on the plant-facing side of the quantum lights I'm building, save for some orange-yellow...

    Quantum Boards Grow

    Yeah it yielded some awesome night sky shots up in the Cascades. I had the opportunity to use the 100-400 L IS II USM (with a 1.4x extender) in Tanzania. Phenomenal. I was paranoid about such an expensive rental, but it was worth it. Edit: and challenging, really. All I have on hand is an...

    Quantum Boards Grow

    I really do need to get a fast, wide prime like that. I used to have a Sigma 8mm fisheye, that thing gave great night sky shots after a slight lens correction. Better believe I'll break out the DSLR once the QB's get here. I'll have things to share.

    DIY with Quantum Boards

    A shorter internodal length, in theory. YMMV. Many other significant factors. Look at the spectrum comparison threads, there are photos of (e.g.) 3000k vs 5600k veg/flower results. If you're really limited on vertical space, I'd certainly recommend a 4000k-5000k light and LST or low-scrog to...

    cree xpe-e

    Read the far-red thread that CobKits linked. As I see it, the fundamentals of supplementals are simple: 1. At most a few watts per square foot. 2. Even distribution is critical. My suggestion? Grab a 2" or 3" heatsink from HeatsinkUSA at the length of your growspace; at every foot place a...

    DIY with Quantum Boards

    Same here. I've ordered 2700K (288's), hoping to swoop 3000K instead. I may or may not have been distracted by videogames when they went for sale... I have eight boards to use at 1400mA in a 4x4' or 5x5' area. If I mount them on a 24"x32" aluminum plate 3ft(?) above the center of the canopy...

    2530 vs 3590 in a 4x4

    Much appreciated; yeah, I'm probably going to run with six at 1400 or eight at 1050.

    2530 vs 3590 in a 4x4

    A big aluminum square plate. How thick? Don't know. 1/8"? Something like that. Four 50 CFM fans dumping air on the center of the top of the plate. An eyebolt in each corner for suspension, and a plastic sheet above the metal one to enclose the electrical. Is 8x QB288 at 1400mA overkill...

    2530 vs 3590 in a 4x4

    No worries, I've been jotting down COB arrangement sketches all week. Appreciate the response. I have HLG's quantum boards written down as an alternative to the 2530's... maybe I should take a closer look at them as well.

    2530 vs 3590 in a 4x4

    You're given a four-foot-square grow area. Select your build: Build #1 — 12 x CXB3590 3000k 90cri 3 x HLG-185H-C1400B 1400mA, ~56.4%, ~330PARW, ~21 PARW/sqft, ~$765 Build #2 — 32 x CXB2530 3000k 90cri 4 x HLG-185H-C700B 700mA, ~49.1%, ~383PARW, ~24 PARW/sqft, ~$775 I feel like you guys will...

    Anyone looking for big passive single-COB heatsinks?

    I have ten SimpoLED-160150 heatsinks that I no longer need, but I could really use more funds for the lights I'm currently building. Retail is listed $33.50 a piece, and they cost me around $40 after fees and HK shipping. I'd like to make some money back towards my current builds, so maybe $30...

    Light design issues

    After an unexpectedly busy summer, I've been able to devote the last two months to completing my light designs. Having a 3D printer has helped, but there are a few things left to nail down. As soon as I finish building these lights, I can show you guys what's really special about them...

    Lets Build A New Light

    I second the call for a parts list... I've been looking for an affordable (read: not shipped from HK) source for smaller pin fin-style heatsinks. Nice driver, too. The HLG-240's and 320's certainly are useful.

    Breaking news about Kinbrite

    I empathize doz, but as realstyles is getting at, the 3590's are in high enough demand that it's ot really his fault. Just got a message from him a few minutes ago, apparently mine shipped yesterday. Hopefully yours will be out the door quickly now

    COBs by string, or COBs by rail?

    I've been using Autodesk's Fusion 360 lately... it's free for hobbyists, enthusiasts, and startups, and is cloud-based (including raytracing). Good deal, but still has some usability issues, Heard from Jerry today, sounds like the 3590's are shipping on Tuesday. :)

    COBs by string, or COBs by rail?

    As far as the strings go, I don't yet have much to take pictures of. Perhaps I'll put some drawings together. I was just seeing if there would be much interest in a vaguely "string" like fixture, not unlike oversized christmas lights. Rest assured that as soon as I have materials in hand...
