HLG 550 V2 Rspec w/UVA Review & Grow

[Stephenj37826]

@Stephenj37826 is there anything in between the qb and the cooling plate?

No thermal interface material required.

 

[Stephenj37826]

I do not, other than asking @Stephenj37826 to hear it from the horses mouth.

3500k + 660nm

 

[Rocket Soul]

The qb96 is 4000k + 630 + 660. By the look it may even be 70cri

 

[GreeneryBob]

Ooooh, 365nm. I just unloaded 1300 bucks on a bunch of cutter nUV and upper UVA, and blue diodes and some drivers and now this happens!
Okay HLG, its almost time to take my money again.

@Stephenj37826 When you're ready to sell me some of those, I'm ready to buy them.

Very nice spectrum

We have a few in stock. Will add them to the website in a few days.

Right, this is the non-DIY version. I would think a DIY'er should be confident in their skills to remove rivets.
A rivet is no big deal to take out, takes about 5 seconds with a drill and the right size bit.
Basically, it wasn't made to be taken apart and messed with, but if you know what you are doing, it can easily be done.

Anyone with an aluminum fishing boat knows how to easy it is to remove rivets lol

@Stephenj37826
Any spectrum chart available for the UVA light?

 

[GreeneryBob]

@Stephenj37826 what brand and power rating of diodes are you using in the UVA bar, especially for the 365nms?

 

[oldbeancounter]

This will be a review and grow from box opening to chop on the:

HLG 550 V2 Rspec
UVA Bar

I am going to review this light, and put it up against some other manufacturers in a grow.
Please be respectful of this product and its review. Thank you.

@Big Perm
I wondered what diodes the reds are if you know?

 

[oldbeancounter]

@Stephenj37826 what diodes are you using in the UVA bar, especially for the 365nms?

Not sure this is 100% correct but I read on HLG website
4 blue @ 405nm
16 UV365-BUV 385nm
this video points out the different spectrums.

My HLG 550v2 clone from Meijiu runs way hotter than 110F. I wonder if it’s cheaper diodes. The plants still seem to love the light.

Osram Osolon ran at 280ma or roughly 61% efficiency.

Yes we will be bringing those back as well as a veg specific "rspec" board.

Thanks for update

 

[Ashtray3000]

Would two of these be too much for a 4x8 tent?

Be perfect

@Stephenj37826 is there a lux conversion factor for the rspec board yet? For those using a lux meter instead of a par meter
