Another silly question is
Maxspect is about 3x cheaper than other brands
question is... what so different between maxspect vs other brands of LED fixtures ?
Kevotron,
being made in Asia makes the first big cut in price. Most other companies produce locally; Giesemann in Germany, Pacific Sun in Poland, tons of smaller and larger brands in the USA. This makes labour costs more expensive, then you have the lenses, which Maxspect has retrofitted and cut some corners with. On one side they have been inventive and pushed the envelope, for me the long-term quality will tell us more (that said, how long should a lighting arrangement live? Technology marches on). Also, their LEDs were a different quality, but this is now an buyers option. They do not yet come with dimming and full-feature computer control, which is a costly option to build in. Then comes the optical design, which is for me anything but attractive. It's just another black box!
In the end, I think one can say you get what you pay for, but I do think you are getting quite a bit for the buck with the Maxspect system. It can be tweeked and the size is small enough to be a usefull modular concept solution for larger tanks. For tanks deeper than 24"/65cm, one may find they do not penetrate deep enough, even with their lensing system, which is actually a light bundling system using cone reflectors and optional lenses.
In the end, for most aquarists running a smaller tank, they are the budget solution that works. Plus their exchangable LEDs allow for some experimenting with spectrum (I know of no other system that allows this with ease) I wouldn't hesitate to recommend them, even though I would probably build my own, as my tanks are atypical and relatively difficult to illuminate. Still, as a unit for experimenting with spectrum, they are very attractive!
Let me put it this way, if I lived in the USA, I wouldn't hesitate buying a bunch of them. They are dirt cheap over there. In Europe, they just compete pricewise with other units, due to import duties and our local tax. (read 38% more expensive) Yes, I'm jealous!
