nice to see a review on these, I considered getting one until I realized the finnex for a 90cm tank was cheaper.
I would love to add some more PAR rating. Guess I could do a test on the 110G when my anti algae treatment has been finished. Can lower the water levels to get the missing water depths will update with PAR readings as soon as I can. Will have to wait 14 days though, got BGA for the first time so trying out an algaecide from easy-life.Great LED for the price, I reviewed a small one back in June that I put on my spec. http://www.plantedtank.net/forums/1...ec-light-upgrade-replacement.html#post9787338 Still happy with the light - no complaints yet. It does run real hot on max setting, but I never run it that high. I'd like to see more people's opinions on these cheap little beasts. Thanks for the par ratings. Any chance on posting par ratings at different standard heights and on different settings? I would be curious at the par at 16" 18" 20" 24".
Great review btw.

Sorry for being unclear, but you guess correctly those are the PAR readings for the 7 different intensity settings on the included dimmer.Good write up, tho Im confused with your PAR readings. Is each level a different brightness using the dimmer?
Looks really nice. Makes it really hard to justify the almost five fold price gap to some of the more common led fixtures. And they generally only have half the strength as these units as well. Though I did notice that the fixtures from the maker above 60cm wide are not as available as those at or under 60 cm. The price jumps quite a bit as well to around 120$ for the 120cm version (depending on where you buy it). For example the closest eheim is around 200$ and plus the 100w power supply ends up at 250$, not the same big price gap as for the smaller 35$ version (60cm) but still half the price... Though the chihiro 120cm is at 65W where the eheim is just at 40W.Great review!!!.
I have a couple of these units ( 45cm), and share the same experience as
I like the dimming feature and the optional adjustable legs, highly recommended.
Here is picture of the 2 units on a Cad light 15 gallon, 50cm wide tank ( over kill) , both units are set at level 4, they are timed to come on & off 2 hrs apart.

39x .3 =11.7W x3 = 35.1Closeup on the leds, three rows with 39 LEDs each totaling in 114W
Doesn't add up..Specs
Chihiros A-Series 39W (60 cm)
117 x 0.3W LEDs
Rated at 5800 lumen
so PAR measurements were 12" from substrate to light at the center of the tank?For the 13G (30cm / 12 inches from substrate middle line of the tank),
39x .3 =11.7W x3 = 35.1
Doesn't add up..
Next:
so PAR measurements were 12" from substrate to light at the center of the tank?
My concern is that the PAR readings from 12" in the 13 gallon and the measurements taken from the 29 gallon ( which is 50% taller ) are almost the same.There is a difference between diode watts and system watts...
either way they claim to be getting over 140Lumens/Watt..That is a hefty claim..
In their defense.. PAR is really all that matters..![]()
Yeah that is a hefty claim indeed and most likely not very accurate, guess it all depends on how and where you measure? But yeah the par is what matters and it would be sufficient for most users I would say.There is a difference between diode watts and system watts...

Like I mentioned the light on the 29G was on an adjustable mount and thus closer to the surface. Just double measured and the distance from the fixture to the substrate on the 13G is 12 inches and on the 29G it is 15 inches so not really a huge difference there. Hope that explains the almost similar results there.My concern is that the PAR readings from 12" in the 13 gallon and the measurements taken from the 29 gallon ( which is 50% taller ) are almost the same.
So either this thing can penetrate like all heck, or somethings is amiss.
I would be interested in seeing how the largest fixture does on a deeper tank, like 20+ inchesYeah that is a hefty claim indeed and most likely not very accurate, guess it all depends on how and where you measure?

Yup it is and it is noticeable cold. Reds will not pop with this light that's for sure.re-read this review, really thinking about getting a 80cm unit for a 20 long I'm going to be starting up.
My only concern is the rated color temp of 8,000k... thats a bit cool for my liking.
Is it really 8000k?
:crying: sigh... Its almost a perfect light.. Why would they make it 8000k instead of the industry standard 6500k? :frown2:Yup it is and it is noticeable cold. Reds will not pop with this light that's for sure.
I believe 8000k is ADA's standard for their lights, which I personally prefer.:crying: sigh... Its almost a perfect light.. Why would they make it 8000k instead of the industry standard 6500k? :frown2:
