...All Things Vero...

Yes the meter's angle towards the light makes a big difference. But is in consistent and is told by most companies to have it flat. They even sell leveling devices. So we use a flat orientation for all readings and reporting.

Apogees are round...and can capture light from angles better.

Li0cores got this going on...

But to touch on the point that raz made about plants...they can absorb from all angle. Here is a good general light study but touches on vertical/side lighting for increase canopy/surface area.

Have you had a chance to compare the apogee sensor to the licor ? I was wondering if the extra price is worth it or not. My biggest concern is how well apogee sensor covers the 660 nm peak, since the graphs they have in their documentation shows a big drop someplace near that range.

I have an Optic (Vero 18 ) 120 light. I've read a few posts from people who were concerned that the magnifying lens that it comes with sits too close to allow ample airflow, and could create an issue with too much heat buildup. I've also seen comparisons of the light output with and without the lens, and the lens appears to offer a substantial amount of improvement.

Is the the consensus that in this application the lens presents a problem (or a highly likely potential for a problem)?

I wondered the same thing when I first saw the large glass lenses. But when I tested the temp droop of the 200W model it was under 3%(from memory) with Vero29s driven at 2.15A so the Tj was well under control.

Excellent -- thanks for the confirmation.

Ive got gelid GC extreme thermal paste coming and I'll tap and screw the cobs to the heatsinks

These are the drivers I've now got

PS: I just held + and - DC terminals of LPF-90D with no load and also with load and nothing happened. And my hands were moist too from washing hands. I think 42V DC is not much of a monster. But good to cover them with something to avoid short with foreign object. Quote me in some other thread if your experience was different.

How ballsy of you! In the past I've touched the solder pads of the Vero 18 with the tips of my multimeter, with voltage showing on meter.

I appreciate your insightful words and will follow your advice. Thank you for being such a reasonable person, Robincnn!

Thanks AP. Don't trust everything i say. When i got a 220V shock during childhood I saw a green spark. I kept telling everyone for years I saw electricity and that it was green in color.
I still don't understand completely how much DC voltage unsafe. Some websites say even 12v can kill you in right conditions. I would not have touched the wires if it were over 60 Volts.

Now the painfully long wait

Unless you're avoiding taxes by getting it shipped from China, you'd better buy Veros at Digikey or SOS electronic.

I'm in the uk,this is the cheapest option and I don't have to pay double the tax like I would on digikey

Alright just saying. I'm in Europe as well (not UK) and we've been very happy with Digikey as in all three orders I made we had free shipping which took less than a week and no one charged us with neither import tax nor VAT. Might be different in the UK.

Shipping is £12 then vat and tax on top, then import duty ontop of that. Ordered 5, only need 2 so I'll stick them on eBay or something when they arrive

I see that sucks. Technically I have to pay VAT and import duty. But since no one asked for it, I'm not gonna feed this corrupted state anymore.

Exactly lol whenever i ve ordered anything from China I've never had to pay any extra, and I don't have to pay tax their end either so I end up paying the price it states. £18.71 per cob it worked out at

Hi here,

I m about to command 3 vero 29 on digikey

http://www.digikey.fr/product-detail/fr/BXRC-30E10K0-L-23/976-1253-ND/5180225

i dunno if its v2 version ???

but i'm confused about the Pico ezmate .

Refered to this site http://kingbriteled.en.alibaba.com/product/60272106242-801593357/LED_cable_for_Vero29_V2_MOLEX_LED_cable_0688014085_Length_0_305m.html

they say the product reference pico ez for vero 29 is 0688014085

But on digikey http://www.digikey.fr/product-detail/fr/0688014085/WM9595-ND/3880995?WT.z_cid=ref_octopart_dkc_buynow&site=fr

same reference but they say its for vero 12 !! ???
and the "max" i found on digikey is for vero 18.

so could you help me to find right pico for vero 29 plz ?

Also , i find only lens for vero but not reflector ( i prefer reflector )
Does it exist , reflector 90° for vero 29 ?

Thx all for help

The following three links are your best bet for the Molex Pico-EZmate IMO (28 AWG wiring fused to 18 AWG pigtails) The link you referred to is 28 AWG fused to 20 AWG.

http://www.digikey.fr/product-search/fr?KeyWords=0688014226&WT.z_header=search_go

http://www.digikey.fr/product-search/fr?KeyWords=0688014225&WT.z_header=search_go

http://www.digikey.fr/product-search/fr?KeyWords=0688014229&WT.z_header=search_go

The only difference between these three links is the length of the pigtails. 152mm, 305mm & 458mm respectively.

As far as the reflectors I cannot help in that area. Hope this helps.

Also to add to that all the Pico-EZmate's will connect and power any of the Bridgelux Vero line the only difference between them is the wire size.

You might as well just order the lot from kingbrite? IV got 5 vero 29v2 coming with the connectors

And yes they are the v2s in your link mate

Thx guys for help ,

rosswaa :

i would like to buy via kingbrite but got 200$ .
Thats why i buy 3 from digikey

3 vero 29 = 70$~
3 arctic pro 11 = 20$~
3 MW NPF-80-42 = 130$

They will run at 2.1A @ 38V~ ,
typical values so ....

will do only for bloom so i choose the 3000K, but i see there is 2700K.
Might be better spectrum for flowering ?
but cant find vero29 datasheet spectrum for this color temp .

Thx again for help

edit : looking datasheet right now , well for bloom , we want more red, right ?
It seems vero 29 decor series has more red than vero 29.

The peak for vero 29 3000K CRI 80 is at ~610nm ; 20% relative power at 700nm
the peak for decor 29 3000K CRI 95+ is at ~640nm ; 50% relative power at 700nm

So not better for bloom period ?

 

[rosswaa]

That was the total price for 5.

I'll be using 3000k for both veg/flower because of ease and works well in my setup

There's been a lot of discussion about CRI - the general consensus is that the higher CRI cobs may have a slightly better spectrum, but give up a lot of efficiency in the process. Basically the higher CRI cobs put out less light, so it's better to go with the lower CRI cob that puts out more photons. I don't think the decor series is available anywhere, so that's a problem too.
The Vero 29 3000k v2 puts out a lot of red and will work good for flower - it's what I"m using now, but I supplemented mine with some royal blue 3 watt LEDs since the 3000k v2 is pretty low in the blue spectrum (less blue than the Cree CXB 3000k cobs). The Vero 29 4000k is popular too - it's got a good red spectrum with a bit more blue than the 3000k. If I were to build a light today, I'd probably go with 4000k Vero 29 or 3500k Cree for flowering. If you want an HPS like spectrum, go with the 3000k Vero 29.
