Difference Between Vero 18 and Vero 29

Can anybody tell me what the difference between the Vero 18 and Vero 29 is? I've decided to buy the Optic Vero LED light. The 250 watt comes with the Vero 18 and the 200 watt has the Vero 29. I'd rather have the 250 watt but not sure what the difference is. Thanks in advance.

I oredered a 250 watt vero29 from optics the beginning of August so i dont understand why u cant order a 250 watt and i dont know the difference between Vero18 and Vero29 but the consensus i got was the Vero29 were better

On their website it says the 250 comes with 4 Vero 18's. I'm thinking the 18's are just smaller each but that's why there are 4 versus the 200 having 2 Vero 29's. I'm about ready to pull the trigger but just wanted to be sure one wasn't older technology than the other.

Wow dude your right was under the impression i had vero29's but there vero18, im going to add the 200 watt Vero29 to fill out my 4x4

Bonjour
Just read "all things vero" thread...!
Or maybe the difference is...11...lol
No...V18 is 80w chip and V29 140w one...
I would go with V18...more spread...more light!
How big is your grow box? Aim for 30w sq/ft...
Have a great day ★

Same technology just different sized chips then? Thanks

I can't answer your question technically, but from what I understand practically speaking, the 29's will have more penetration, more intensity. So it depends on your growing style. If you grow tall plants, you might want the 29's. If you grow in a scrog, the spread out light of the 250/18's might serve you better. From comments others have made, it sounds like the 18's came out first, and then the 29's were a "next generation", bigger better brighter thing. I've also read that the 18's are more efficient... so I don't think there's anything particularly wrong with them.

I'm running two 120's right now -- which is 4 Vero 18's -- in a 2.5x2 space. First run so I can't give you harvest numbers, but its bright as hell in there... if that helps. :)

Sorry I can't be more specific, I've gotten into this late in the game and I'm still in the early part of the learning curve myself. Hope something in there helps.

Actually the number in the name is the diameter of the LES (Light emitting surface 18mm vs 29mm).
And TBH I think that more chips will have better penetration and that your theory isn't valid. V29 will have slightly better efficiency in this case but V18 could make this up by having more evenly spread light sources, resulting in more evenly spread photons and better penetration.
So I'd say that it's reasonable to expect about 25% higher yield with the 250W version (same weight per watt).

Thanks for the corrections, it didn't seem like BigEasy was getting the answer he was looking for so I tried to cobble together what I've read about these lights. When I was speaking about better penetration, it was based on the comparisons made between the 120 and 200 unites -- each having two 18s or 29s -- mostly from JimmyIndica's thread that compares those two. That's always the problem with repeating what others have said and not having a firm understanding of the underlying technology, so thanks again for setting the record straight.

More Vero18s at 60 over the scrog at 12inches and Vero29s at 90 or 120 16in to 20in for the taller single plants. Ive noticed that the vero18s have to be put little closer to get the intensity I like and that cuts down on coverage a bit.
IMO Lenses on.
Lots of variables into the predicting of how a given fixture will perform #s wise.

The 200w Vero29 model provides about 65 par watts. The 250w Vero18 model provides about 75 par watts. This is because the V29s are being ran at test current and the Vero18s are being ran above test current. Vero 29 lamp output at about 40% efficiency. Vero 18 lamp at about 35% efficient.
