Hagen has gone the whole hog with its Fluval LED range, and the nano model compliments the offering at the smallest end of the scale, says Nathan Hill. 


Running at just 6.5W, and churning out 9000K, clean white light from a cluster of 14 diodes, the ECO Nano is a scorcher of a light for the budding pico aquascaper, or micro-reefer.

This light is dual purpose – it’ll work on either a freshwater or a marine set up. The lens allows for a 120° spread, so you’ll not end up with a spotlight effect, laserbeam of light shooting straight down.

Hagen claims the light features C.O.B. technology (meaning chip on board), which it suggests leads to heightened efficiency and output. To my eyes, it looks like a punchy LED. 

Installation, just as with the other Fluval nano LED designs, is a sore point. The fixing has to be adhered to the glass, and once it’s on, it’s on. If you break your tank, or move to an upgrade, you’re stuck. It annoys the heck out of me, because I get through lots of tanks, and want the option to switch it about. 

The other thing with the adhesive sticker is that on really hot days, it loses its stick. I’ve come home before and found mine laid back at a casual 30° angle, peeling itself away. Worse still, when you do initially stick it to the glass, you need to wait 24 hours before adding the light. I’m way too impatient for that jazz. And seeing as I can’t establish how to extract the cable during the curing period, it’s just hindrance after hindrance. 

With the holder in place, you need to screw the light on to it. Three screws are involved, and there’s an included tool for the job. Avoid cross threading at all costs — easier said than done. Then, once in place, you can swivel it out of the way for maintenance. 

You get around 50,000 hours of light (proposed) but I’ve not had mine anywhere near long enough to comment. 

Verdict
If you’re not planning on changing it, this is a great light. If Hagen made a screw-fix, removable holder, it’d be a billion times better.
