Hi Its Bill from ReefLEDLights
Here is my opinion on Cheap but Reliable...No Such Thing...
Inexpensive and Reliable...Yes
Many Import Ebay Fixtures use noname parts... Drivers and Powersupplies often do not have any serial number or manufacturer labeled on them. These critical parts are not IP63, UL or CE listed. In fact some of the these are open to the air which allows for salt ridden dust to collect. This does not lead me to conclude that these "Black Boxes" are in anyway safe or reliable. A UL/CE Listed enclosed Meanwell Driver or better driver and powersupply.
Other things like Thermal Management are critical as hot electronics simply do not last.
Many say $500-600 is too much for a LED Fixture. We say that this is rather inexpensive compared to the alternative. Back in the day a MH Bulb was $89 the Reflector $125 and the Electronic Ballast $250 or $464 and you have to replace the Bulb every 9 to 12 Months. Dont forget the cost of a Chiller and electricity.
Another option is a somewhat moderately priced Chinese Light for $250-300. These may or not use Quality Binned Cree LEDs so spectrum may be a question and they generally have a life expectancy of 18-30 months. Replacement stresses corals as you may be without a light for short of a week.
Our Solution is the
Sirius XTC which is more powerful and less expensive than the Ecotech Radion... This after shipping is close to $600 which is a better option than MH. For those who want the same performance and reliability but at a cost comparable to a Chinese Import we offer the
Sirius XTC DIY Kit which is bare bones and very easy to assemble.
The XTC is a 400 watt MH equivalent designed to cover 24"x24". If your interested an a custom DIY for a 10 Gal we can put together a DIY Kit using solderless connectors and a Makers Heatsink...This would be around your target of $100 and you would have Binned Cree LEDs.
If you have any questions please feel free to contact me.
