I don’t know the details off the top of my head, but I looked at those and they are junk.
If you go ebay etc you can get the Mars Aqua 300w at around $170. I went with 3 of them after a lot of debating with myself. Love the one I have on my 75
Well you could be right but ho did you determine they were "junk"?
Yes 1/2W diodes but at least they are lensed (reflectors)..90 degrees I believe.

Safe and Power Saving: Isolated energy design, UL/CE/ROHS/FCC certified,
Don't think ONE "black box" has any real certs..
Actual wattage is only around
Mars Aqua lies as well as their "selling watts" i.e 3w "class" diodes run at 2W..maybe..
but yes stronger than the above..
Depends how shallow and what your goal is..
Now not tryoing to "sell you these.. They are budget lights .. but I think that have a niche..
BIGGEST catch is the possibly honest 5000hr lifespan..
typo or not? Lots of Chinglish w/ these lights..
Lets do a little "analyses" of the Mars Aqua:
- 100pcs) High Intensity 3W Epistar leds
- Lens Angle: 90°
- DB: 58.9dB
- Input Voltage: AC100-240V
- Frequency: 50-60Hz
- Lifespan: 100,000 hours
Average forward voltage on these lights is around 3.6V
Never saw one w/ a driver that exceeded 550mA
3.6x100x.550 = 198W
Now w/ some luck the emitters have better than the generally feeble 50Lumens/watt rating..
Most 1/2W diodes are approaching 100Lumens/watt
Yea lumens are for people but it shows a level of efficiency..
Epistars are capable of this efficiency but do you believe it's in these?
Thankfully there is very little waste sideways like for tubes and bulbs.. and yes they WORK just fine.
now 100,000hrs lifespan? Not in this universe..
Another poster I agree w/
The MarsAqua is a reasonably well made, basic, standard, slightly old design of an led fixture. Does it provide enough light to grow corals, absolutely. Is it even the best made inexpensive led fixture out of China, probably not, at least in my view. It has a painted steel case that can/will rust, some others use aluminum cases and powder coat them which is much better. There are a lot of other differences as well (fan quality, heat sink quality, stainless steel fastener quality, driver quality...), but you should really do some serious studying of led fixtures......................
