Ianrusso.... Those are great pictures but can u please explain wat tea funk it has to do with cheep aquarium lights vs brand name fixtures?
Are those aquarium lights they are using?
If so what kind?


If not... Well great pictures anyway...

Someone posted this set of pics with PAR ratings and boasted about the PAR ratings being very high. I was stating that these PAR ratings are INACCURATE because they were taken out of water. Lights DO NOT have the same PAR as when they are over water. Water reduces the PAR of LEDs by about 30%-40%.

The ones I purchased(dimmable with lenses) were tested over water and received TRUE PAR ratings. When I tested them out of water the PAR rating was stupid high.

Someone who took that much time to take that many pics wasted their time. And was INACCURATELY informing other members of Reef Central.

Feel free to believe what you want, buy what you want, and grow your coral how you want. FACT is, those PAR ratings are INACCURATE and I was just trying to help out the Reef Central Community.

the only true ways to rate them would be if some none biased individual would put each of them under a spectrum anylizer to see how much light at what wave lenghts they are actualy producing. Then run the lights for an extended period of time and watch for break downs and degradation of the light comming from them.

With LED's long range testing is especialy true because there are so many variable with heat being one that can completly change the picture between a system right out of the box and one that has been running for year or two.

Bhe best advise I can give is generaly an individual gets what they paid for. If the $150.00 gixtures were as good as the $2,000 fixtures then no one would be buying the $2,000 fixtures. However I have yet to see a manufactured fixture out there one could not build themselves in the same price range and know exactly what they have.

TropTea, your information is inaccurate. Whats your email and I will send you pictures(file is too large to upload to RC) of growth on my ACROS from my $178 Chinese LED fixtures that are dimmable, have lenses and have had the PAR tested by ME, under water.

For $178.00 each, the par tested is higher than the Oraphek and Radion. So yes, $178.00 lights are just as good if not better than more expensive lights.

And your comparing a $150 to $2000 is the dumbest comparison ever. People on average spend $150 on a single chinese LED fixture, where a standard single LED name brand fixture here in the USA is $500. Your facts are false. I dont think there is one single LED pod that sells for $2000, and if it does, I would love to see the PAR rating.

See my previous posts for PAR info...

However I may not need the optic lenses for a 55 gallon or a 46 gallon bowfront... correct (Ianwrabb post #1120)? Decisions, decisions, please help with advice.

Or these

[dlterry85]

i'm thinking of going this route real soon. has anyone had any real problems with the chinese units? if someone has been running these for more than 6 months, pm me what unit you have , how long you have been running them and if you are happy with them. a plus would be your supplier and price you paid. tia

has any bought the pharos systems that are out with the controller and cloud simulation? coralvue does not support these anymore and i was wondering why?

[bhazard451]

I'm deciding between the $165 lights and the Nova A4/A6 lights. I really like the design of the NOVAs, and they are also dimmable as well (Sam confirmed). I can change LEDs easily on the Nova too. I'm just wondering if its worth the extra cost over the $165 one.

From what I have read the above lights have lower par numbers (Taotronics specifically) and are not dimmable. 51 pages on this thread and other reviews have suggested this. To me spending a few dollars more for dimmable lighting that is brighter seems well worth it, that is should one need the extra light intensity. But I do appreciate you suggesting another system Travis

Please post the link you are referencing with the NOVAs.

[Travis1787]

I understand I just like these cause I have yet to find one person give a bad review plus there in states so fixing and shipping is faster is there is any issues...

There are many in this thread using them that have nothing but good to say... There 120 watts just as the taos or aliexpress units.... and as for the par readings? Who knows how legit any of them are or if they were done right .... There all the same black boxes too me some with dimmers some without... I mainly care about customer service for when. Or if something goes wrong and from what I've read they have that better so far...

[Travis1787]

I really do like the taos I've seen them in person but just not fond of an ebay seller being there when I need them fixed

NOVA A4 is $230 shipped. 48 leds 120w
NOVA A6 is $293 shipped. 72 leds 180w

The design is updated over the $165 one, and seems to be worth the extra cost. The fans (10-15c cooler design), modular capability, and replaceable leds being the main updates. Dimmable too, which none of the ebay ones are yet.

Just buy from a seller that has been around for more than 2 years with over 1000+ feedback. They won't be going anywhere. Discuss the warranty with them and how they'll handle before buying.

More info on this type of model:

Feature:
1. Newest cooling system, revolutionary heat dissipation design, greatly alleviate the internal thermal cycle, 10-15 Celsius lower than its precursor in performance.
2. Brand new technology in fans will be more long-lived, decreasing 50% noise than its precursor.
3. Built with 60℃ Second optical lenses, the illumination is 15 times than the universal version in the market.
4. Using high quality EPI 3W LED light. (I think you can choose Bridgelux too)
5. Can 100% reach or even exceed rated powers.
6. Modular assembling is much more convenient for maintaining and repairing, can replace LED or power individually. No glue and glass.
7. Intelligent monitor system, ensure the whole equipment in a good working state and automatically alarming for breakdown.
8. Using advanced isolated power driver, UL standard output voltage which is lower than 45V DC. Soft starting protection to avoid the transient currents impact, effectively protecting the LEDs from high voltage damage.
9. 85 to 264V AC power input, 50/60HZ working frequency, suitable for global residential energy environment.
10. Aluminum drawbench face shield design, compared with traditional glass shield, better heat dissipation; shockproof and fall resistance.

No paypal, no reviews, this seems like a great leap of faith to venture down this path bhazard. How would one even go about buying this and ensuring receipt, I only ask because I have never dealt with overseas vendors in this fashion. Thanks for the post however

Sam Chen from Evergrow has posted in this thread quite a few times, and there are a few people here who ordered from him. Paypal is accepted.

The reason there are no reviews, is because the unit is very new. I'm in the process of buying the NOVA A4 now, with Bridgelux leds and 90 degrees for my 34g nano... just getting a link made. I will literally be one of the first ones getting it, if not the first.

This model can be repaired easier by me as well, such as if there are dead leds or parts after shipping. I'd rather have easier fixes I could do myself instead of having to send the unit back to China like the $165 model.

I see 60, 90, and 120 optical lenses available? What is preferred for a tank < 24 inches deep (46 gallon bowfront, 55 gallon, 75 gallon)? I have read you can customize them, how so? There is not customize tool that allows one to do this.

Also, where can you pay with paypal, I am not seeing it should I decide to go this route?

Email Sam Chen directly and request the parts you want. They need to create a link on Alibaba to order paypal wise. They are in the process of doing that.

sales02@ledgrowlights.cn

I went with 90 because my tank is less than 24" wide. I would go 120 for anything else. I went with Bridgelux leds over Epistar too.

Where does it show or can you find what optic lens is best for a given tank?

What is the advantage of Bridgelux over Epistar?

Someone on here said optic lens works best for tanks 24" deep or deeper. No optic lens for 24" deep and less deep. Optic lens for more water penitration.

[Travis1787]

So which for exactly 24inches tall 18 wide would I use then?
