Mau5Capades: builds & grow journal

A little disappointed to see burple yeild close to white COB. Any difference in smoke report
Would like to see how the yield comes with them together.

Did you power 3 cxa 3070 with that hlg 185 1400
I wonder if the power supply could have handled a 4th 3070

Just curious if you considered the lens as an option instead of that ledil reflector. They cost about the same and @REALSTYLES panel seems to be blasting some serious radiation with KB 100mm lenses. I will test a lens soon.
Ledil reflector is great too. You can get some idea about gain from first 2 plots in attached image
edit: all values in PPF

The buds from the 3k cobs actually had better color from the purple strains, and better density in the colas. its all mixed up now, so i have no way of doing a smoke report difference unfortunately.

Thanks for the chart, the difference with the angelina is pretty substantial using my $30 lux meter. I am considering lenses for the next build. You guys can probably tell by the pictures that the other side of the room is still HPS. So i have some work and investment ahead of me still. thinking 32 cxb3590 @700mA just like supra and realstyles.

if you get a chance,can you do a wiring tutorial on how you wired the shroud?

thanks

no problem. post #7 on page one has some additional detail as well.



ground wire comes from AC power in and is attached directly to the gnd wire of the driver. since its all aluminum and the driver is aluminum, attached with metal screws, its all grounded.

What is your ground wire running to? Case of PSU or heatsink? Maybe sandwiched between both lol

I tested HLG 120 and outer case was anodized aluminum and it does not conduct. May be screw conducts. Not safe to assume heatsink and cover grounded because of direct contact with heatsink. If you have multimeter good to check if fan cover/heatsink grounded though heatsink.

Thanks @robincnn safety is an important concern for me, esp running these fixtures at 220v AC in. I will pull one down and put an multimeter on it and probably have to sand the contact point between the driver, heatsink, and shroud. Guess heres another benefit of modular. I can pull a single unit down and work on it for a day or so with out losing half my light like if it was a 9 cob fixture.

For those of you who like videos &/or don't like reading. here ye go. Mau5capades Season 1: episode 1

I think that is due to the lens cover in the BML. Similar thing happened with GGs side by side with CXA3070 vs Apache.

Great numbers tho 1.4 not too shabby!

@SupraSPL I think you are correct about the higher end production fixtures putting some well tuned optics in their products. The BML appears to be a simple plastic cover for UL listing cert, but it must be doing much more than simply keeping water out. It also seems like you have been putting significant effort into optics, reflectors, and trying to ALL of the photons to the plants. Please hurry up and figure it out so the rest of us can copy your homework. I think running all LEDIL Angelina's will be a good start for me, just like GG. The standard 120 deg bare cob seems to just throw light everywhere. My previous tent grows with bare COBs were exceptional due to all that reflectivity. I hope to capture that tent magic with this grow by adding some large reflective panels to the walkway side.

I thought the BMLs were epoxy embedded for IP67 ? On my illumitex its lens plus embedded in epoxy

its a 100k potentiometer (for dimming) from amazon.com with a decorative knob

Any specifics on that pot, like linear or whatever else it could be? I'm in need of one. Awesome build...again!

100K ohm rotary linear potentiometer can be used like this. I like the 100K ohm wire wound multiturn pots like this cause they give you a much more precise adjustment but cost much more compared to a single turn.

Thanks C1! Duly noted.

The bourns pot are very well made and nice to use, but there are some benefits to the single turn also. For the type of adjusting we are doing the single turn is reasonably precise and you can mark down the corresponding current on the board. It also allows quick adjustments

Someone can come up with something nicer than my scribble but you get the idea.

I agree, When I think of the bourns potentiometers and precision adjustment I think of the ones with the dial counter on them for keeping track of where you are at in your adjustments.
Something like the one in THIS link. They can be had cheaper then this. This was just the first one I found to link to lol

maybe similar this one?...

...on other things... thanks Growmau5 for your vids ... i saw your last and my inspirative way dont stop...

..my pov... on reflective walls... down the lamp only...not for the entire walls...im thinking on rigid insulation panels with a high reflective side for covers the walls and make frontal an side separators movibles...



we can use cartoon too but seems to me not much durable thing...



...i saw you using reflectors on your cobs...my pov again... why not make your 90º diy reflector on similar way to totalgrow lamp or similar rectangular lamp...



...you can use your metal sheets an do bigger or shorter or larger... what you like...or need... ...i hope you or other diyer bro catch the idea...

...Guod use isolation panel too... @guod please refresh me what you use on reflective walls... some type of foam covered with aluminium sheet?...

...upsss... the pics and link are only for examples or ideas...

...and... curious video for vero 29...


...or cxa1830.......


lol...maybe too much offtopics....e function actived... desactived by Growmoau...thanks again...

pd1... for my inexpert pov... if we go on lens way... lens and leds needs good auxiliary ventilation too.. on closed lamps or closed tents... ...Psuagro have some bad experience with lenses or maybe seems to me... hot climates or hot temps.. dont help us too...

on reflector way seems to me my idea are more economic way...only need reflects on the perimeter of the lamp not cob by cob...

...and use not only metal... we can use wood or carton too...for the Diy reflector...

...and thanks for sharing her probes or temp test with reflectors or lens too......

...sometimes i like some mendo dope music too...


...and some of her tutorial vids too...... ...looking on the positive way...

How to grow "Mendo Dope" from Seed - Part 1

How to grow "Mendo Dope" - Part 2 (Vegetive State Of Mind)

How to grow "Mendo Dope" - Part 3 (Transition)

pd2... and we can use my idea for reflective walls and simulating big reflectors too only curving or inclined pointing to lamp on one part of it... more economic way too...

pd3...@Growmau5... please if you go on reflective walls ...please share more info and pics about it... what size, composition prices etc... seems to me polystyrene or similar with aluminium sheet... thanks in advance...

@salmonetin I like your ideas. My Lowe's has the rigid foam, one side reflective for $10, so that was what I was planning on using.

I love building things, and am open to experimentation for the next build (replacing the HPS side). But for now, I am somewhat committed to the LEDIL reflectors for this build. I need 10 more, @ $8.81ea, so ill just buy them and bitch about the price.

On the next one I am considering lens, but wondering if there is more value in a silicone lens vs the glass ones from china. Or these metal reflectors:

for light jockeys
Studio-Fader 100 kΩ Mono 0.5 W linear ALPS 193743

With all this pot/fader porn, this is like a Pro Audio Thread. Props for the info guys, really appreciate it.

The reflectors are superexpensive, translucent and maybe not worth the investment. Have you thought of painted aluminium bowls?
