    Following the Jhb reef meet- to show we do talk marines and not just :peroni:

    Firstly we tested the Seneye unit with a par meter, to determine how much bang for buck you get in terms of a par reading.

    We held the 2 meters underneath a std mh globe:

    Seneye = 103

    The par meter Reading = 101


    We then tested a PAR38 globe 19w (@toolboysa), a 72w DIY Cree light unit (@butcherman) and a Ecotec XR30W radions with TIR lens upgrades(@carlosdeandrade).
    All at a depth of 680mm (it should be noted that @vatso runs ozone which clears the water and increases both visibility and light penetration)

    This is what went down:

    Having difficulty to operate the unit manually...

    All in a days work.... After this we compared test kits for accuracy.

    Findings:

    Par 38 = 99
    DIY LED's = 336
    Radion = 320

    Readings taken directly under lights, the radion did have a slightly larger footprint.


    Conclusion

    I was impressed with the variation of light produced by the Radion, as well as a sleek elegant design. The DIY in my opinion still offers the most bang for your buck in terms of LED's (I have run the DIY LED's for a year now and i am still as happy as the day i built them) and the par globe seems to offer an even cheaper solution to Nano tanks.

    If you like the bells and whistles go for the Radion, it is feature packed (although we had difficulty operating it manually- you need the PC interface).

    If you are even remotely capable of soldering wires onto a metal plate I recommend investigating DIY

    If you own a Nano and want quick easy, affordable, no frills lighting, then PAR38 Globes might be for you.

    Nice review

    All units have there place in the aquarium market, its just a case of finding what your need and expectations are and most important what you wallet says you can have

    I would like to test more light units if anyone is interested to bring them around

    Nice thread, but we didn't test vat so light, the one with the optic lens in the roof...
    We did, par of 2000+ and runs at 100000000watts at R0.0000000001 coz we know nothing is free

    Great write up @butcherman. I also agree with DIY being a great way of doing things, you have such a huge selection of LED's, no need for a PC, and with your typhoon controller the possibilities can only be "bright." I must say that I am waiting for the upgrade to my radions, need to add some UV.

    Will be nice to see other led units out there also showing there stuff, like a vertex unit, maybe a Al sol (where was you @Nemos Janitor?:whistling:).

    I was impressed with the readings in such a deep tank.

    This is why I need to figure out how to get my hands on one of these readers so i can test the values of my 600 deep tank with the Vertex unit I got with it.

    Curiosity is getting to me now!

    Howdy Vernon, you could buy a par meter, but from what I remember they will set you back around R6k, or just get a seneye, they will only set you back R1500 and we tested one, and the par readings from the unit were pretty accurate. You'll be able to get one form @bryan at Jungle aquatics. They also measure NH3, temp and pH and an upgrade will be available soon, that will measure NO3 and Alk too. I had one for a whole day, but I run O3 and seneye said that they didn't do any tests to see if this would affect the slide.

    They great thing about them too, is that you can track the parameters of your setup, and it will detect any future problems.

    depending on the light cycle the unit was on. You need to plug in the computer and get it to 100% on natural mode. Did you do that?

    Didn't bring the software @RiaanP, and it was in the evening when we tested the unit, so even in natural/artificial modes, the unit was/would be dark. If I placed it in basic mode and cycled through the various colour options, it still wasn't a true reflection of the intensity (we both know this). I will have a MASA get together at my house early next year (you better be there, keen to meet you:biggrin:) and we'll do some more par readings then, when the lights are at full blast, during the day. I was very impressed at the par readings at the depth and I know I am going to have to ramp DOWN my lights when they are up and running.

    have to redo the test on Vatso's tank on the same depth.
    And actually would be easier to go into artificial mode and change all spectrum to full blast.

    Who tried to understand the manual?

    :lol: Me. The vortech setup manual is worse!

    I am sure I can do that, will organise with @vatso sometime.

    It is Important to note that on a a similar tank with out ozone ALL units would have preformed less!

    A seneye will give you a good indication of the par you run.

    Do you doubt our proficency? we set the unti to natural mode selected the colour we wanted and turned the unit to max. this did not give good results, we tried artifical mode. and even demo mode.
    Perhaps if you weren't treking across the cape you could have helped :tt2:

    We tried a whole bunch of modes. 320 was the higest reading we got.

    everyone tried reading the manual and everyone was confused!

    yes, but it still keep the start and end time and the loop in mind, so even at 100% and only 2 hours after "sunrise" it will not really be 100%.
    Yea, trekking a bit. All work stuff.


    yes... and its confusing or actually incomplete. Try to setup the multiple units. Good luck with that. Their manual can really be looked at and corrected. Other stupid thing is that although you can set the different natural and artificial modes, you cannot switch between them from the software on the PC. Must push the buttons on the unit. A little bit stupid I think.

    Yes, I agree

    Took me three days. finally programmed my units via artificial mode, even have thunderstorms (not that they do anything, but it looks cool, can see my shrimps dancing to "D.I.S.C.O, singing D.I.S.C.O, she is D....")

    I am happy to do some testing again any time must be at night unfortunately as the sun will mess up the readings.

    Light from 250 is enough and up to 400 with lot's of MH over a tank.

    so the readings of over 300 is very good

    here was my sun reading in September this year I will do another one from the same spot
