There’s a reason Mars is switching to the detachable bars for UV and IR as the current design doesn’t really have a benefit vs if they left those few UV and IR diodes out completely.

I think Mars would be keeping that design if it was as effective as you think, it’s not the end of the world that your choice of light doesn’t have enough UV or IR to get the benefits of both. It’s just the facts.

I think HLG has been onto something for a while, and they haven’t put UV into their QBs but have the UV detachable bar light.

the reason the current design doesnt work is...

1. the diodes are cheap shit. (uv diodes are expensive, good uv diodes are very expensive).

2. there isnt enough of them even if they were decent diodes.

3. the pcb probably isnt laid out correctly to give the uv diodes the current they need.

its perfectly possible to make a light with more than enough uv and far red (NOT INFRA RED) all on the same pcb it just costs $$$.

This was also very informative, thank you. I wonder how your UV bar does against the hlg, @Grow Lights Australia ,and others.

We've done a bit of testing comparing UV levels. The first thread is by @Prawn Connery who designed the original High Light.

THC, CBD, Terpene test results – UVA vs UVB vs none

THC, CBD, Terpene test results – UVA vs UVB vs none

As some of you might know, former member Or_Gro did a side-by-side comparing three different types of LED boards with supplementary UV reptile bulbs. He also did a control grow without any UV at all. The test results are interesting because UV clearly works – an increase of almost 20%! But...

More THC testing – UVA vs UVB vs near-UV

We took four samples of the same strain, all grown in coco run-to-waste by competent growers under slightly different lighting set-ups, with two of the samples being provided by the same grower under the same conditions, but grown six months apart (to compare the ageing process or "cure"). This...

Latest UVA vs UVB cannabinoid test results

These are the latest results from our ongoing cannabinoid testing into UVA vs UVB light. The most interesting thing is the results are pretty much the same as the other tests we've done: UVA beats UVB This might surprise some people but this is our third round of testing in two years with 13...

I love the data you guys provide. I don't understand a lot of it, but it's interesting.

I have 4 rapid led UV pucks in my room, they literally blind me if I forget to wear glasses when I go in so they must be of decent quality I’d think?

MONDAY MORNING, MARS HQ, CHINA.
the following account is fictional and may or may not have happened exactly like this.
​
alan : good morning john.
john : sup alan, you good?.
alan : yer good man much happening?.
john : just going through all these emails.
alan : is everyone still asking when we are releasing a light with uv in it?.
john : yer man thats all they care about, uv this uv that, i cant read anymore!.
alan : ok! enough is enough, get mike from manufactureing on zoom we are gona make a light with uv in it!.

mike : hi john, hi alan.
alan : hi mike you busy? have you got a minute?.
mike : yer just on with researching light spectrums and stuff, whats up?.
alan : we are going to make a light with uv in it, there is loads of buzz around uv at the minute and john is sick of reading emails from customers begging for it so we are gona do it.
mike : ok great! i read an artical the other week on uv while i was on the shitter so that wasnt time wasted.
alan : mike do a bit of digging and get back to me asap with some costings.
mike : ok.

2 hours later...

mike : hi alan got some figures for you here, i hope your sitting down.
alan : that doesnt sound good mike whats the problem?.
mike : them uv diodes are a fortune! and the lads are saying we are going to need quite a few of the aswell so we are going to need a completely new pcb, we are gona have to start from sctratch alan, a complete do over.
alan : oh fuck that mike!, you must be able to get them uv diodes cheaper from somewhere? and why cant we use the pcb's we already have?.
mike : the lads said to use the pcb's we already have we would have to remove some of the other diodes to swap in the uv's.
alan : mike it will be fine, just remove some of the red ones and pop on some uv ones.
mike : i suppose if i use the absolute best uv diodes i can get in the very best bins it might just have an effect?.
alan : mike dont you dare use the dear uv diodes just throw the cheapest shit on can find and get it to retail!.
mike : ok alan your the boss.
alan : ok great. mike before you go have you ever heard of something called infra red?.
mike : no.

Maybe they put it in due to customer demand, knowing it is not worth it? And then at a level where it can be used for marketing but not impacting light quality.
The same can be said for the additional bar approach. Now they sell you 2 or 3 lights. They could have gone the route of using an integrated solution with multiple drivers.

Not saying anything about their lights. I don't know them. Just that anything can be read as nefarious dodging of questions. I liked the answer, to the extent that a company marketing a product can be liked.

Yea but integrated driver make it expensive
