My first impression was that this couldn’t be good, with this cheap ass packaging with day written on the box in pen.
Then I remembered that Tunze also gets packaged in cheap packaging and realized I shouldnt judge a book by its cover.

So I opened the box and was pleasantly surprised by its neat appearance. Incased in a plastic T8 Tube were these
3 rows of LEDS. 336 LEDS spread over 1.2m can only bring interesting results.

The guys at the store said I need to connect it directly to a 220v source. No need to use ballasts or starters.
I queried the poles and asked if one side is neutral and the other side is Live and they said nope, live and
neutral on the same side, so I asked what happens if in my wiring I manage to connect the light so that live
go’s to live and neutral to neutral. They weren’t sure so they tested it and told me it was auto switching..
Great so I bought a connector cable as well.

So I got home and put the connectors onto the bulb and fired the bulb up. The room was pitch black and
then there was a narrow beam of light.
This is perfect as the full 15w is being directed 1 way and not all around.

Put it above my tank and tested it through the water. The light is bright enough to illuminate the bottom of the tank nicely.
I’m happy with it, little expensive but its going to last me 5 years and running at 15 w will be a real cost saver in the long run.
I just need to take care not to scratch the plastic tube too badly so that the light cant shine through as easily.

very cool tube, was thinking of doing something nuts like this with some LEDS a while back, was going to stuff a lot into a little strip, as it is there more or less, each taking its share of the voltage and current with a variable resistor to vary the current and make sure that they dont pop. The thing with LEDs and AC is that they only conduct in one direction, so it doesnt matter where you connect what(so them saying its atuo switchin is bull), what i came up with was two scenarios, either they double the number of LEDs and have one half conducting in one direction and the other half in the other direction, hence using 100% efficiency, but this may lead to an undesirable number of LEDs so half the number is used all conducting in one direction, and the switching of the AC is so fast that you cannot tell that the LEDs are actually turning on and off very fast, but here you are only 50% efficient. So it would be interesting to see how they pan out. How bright are they relative to actual T5s and MHs in your opinion? i'm not sure how popular the LED lights would really be in south due to the cost but if you are spending thousands of rands on livestock why not on lights? 15w is very attractive, but maybe not attractive enough... looking forward to your reply:thumbup:

Hi Scubaninja
Autoswitching in this case means that if the poles on 1 end of the tube match the other is automatically switches the poles so that they dont match. If i have 1 side connected with the terminal on both poles, it doesnt matter what pole i use on the other side, i dont even need both, using only live or neutral powers the light up.

Ok for the price of the LED light i could get maybe 12 54w T5's or 24 25w Energy savers or maybe 2 150w metal halides.
This is the 15w LED

This is the 25w Energy saver

This is 2 150w Metal Halides

yeah they are almost on par with the MHs, it does seem the LEDs have the brighter light(more white) but it seems that the metal halides have the higher intensity. they do look pretty awesome though

I think the metal halides are 10000K and i know the energy saver and the LED are 6500K

Dohn, can you take the same 3 photo's again, but this time focus on the bottom of the tank.

I did a comparisons test on the other setup, chucked some glass anemones and open mug corals in there with some silly rock.

sheesh dohn those arent bright at all. two 25w energy savers equivalent? maybe its just the pictures, or my take on them but eish, rather pay for six energy savers. how many tubes will you run on the tank? I know, a reading of the light intensity at the base would do the trick, got a light meter thingie?

The 6,500k light will encourage algae growth, whilst it also encourages coral growth the water looks a bit yellow, so we prefer to look of the 10,000k light which is much whiter.

I like the last one Dohn!

Here's my comment: I dunno if the LED give equivalent light output, like the energy savers do. BUT, 15 watt is in my humble opinion not a LOT of light.

For keep fish only - yeah sure..... for keeping corals - no way..... Then I too would rather go with 24 x 23 watt energy savers...... you can keep some DECENT corals with that light output!

BUT - I do like the idea a LOT though..... will have to wait and see if these light-units become cheaper, that one can add like 10 of them, giving you about 150 watt's worth of light....

just a quick question...i see one can get the led flood light.

do you think one can compare it to a mh?

Not at all MHs give off a hell of a lot of light, wheather or not our tanks need so much light is a different question, MH could be over kill but most sps tank still concur they are the best.

to really compare the led and mh you would have to measure the PAR I dont think the naked eye can see it, however if you look at the last pic with all the lights on there is a strong beem og blue on the right showing that the MH over power the other lights.

I currently run a am 250w and 4 t5s all 10000K but think 20000K mh is the way to go.

hi there, you cant compare the rated power (input) of the bulb to the light output. for example, a incandescent bulb of 60W gives of maybe the same amount of light as a 30W energy saver. now LEDs are even more efficient at producing the same amount of light.
