Ill be doing a little analysis when I get them. I have the new Apogee PAR meter that supposedly measures the blue much better. Game plan is to dial them to the same PAR my 360s are at and then slowly ramp up.

Please keep us posted. From experiance the AP700 puts out a lot of light. Personly I can not increase my intesity past 70% with out frying some SPS. Everything seems to get plenty of light no matter when positioned.

My buddy did take some reading with a Seneye. @ 70%, I was getting 300+ PAR everywhere just off the sandbed. 200+ @ the sandbed.

You need to download the apogee calculator for the new mq-500 sensor. It does calculation for underwater immersion and the opaque lens on the apogee sensor. Tests are showing that the mq-500 is off by 32%. Open air does not need the formula but if you are doing underwater measurements then you do.

Yes, I am aware of this. Not sure what calculator, I just multiply by 1.32

1.32 gets your in ballpark but now there is a calculator that puts out exact measurement depending on depth of sensor. I pasted the link to the spreadsheet above.

Ok, what I don't understand is in their example the displayed par value is corrected to be much lower. I thought the readout was way low, that was the whole point.

Anyone have their AP700 die? I have had 2 of them just stop working and have another coming. I am still under the 1 yr warrantee but I am very nervous that once the warrantee is out, I may be screwed if it happens again. I live in South FL and there are thunderstorm all summer and power can flicker often. I have the Kessil plugged in to an Apex. Nothing else on my tank has gone out from any of these storms, but the Kessil twice in under a year.

When the first unit went out, but power supply was fine, but the light would not power on, just dead. I really like the light but am considering selling it for something else.

Had some alone time with a seneye par meter here's some quick measurements taken ... Lights are 7" above tank (60x24x24)
@ 1" below water level @100% ocean blue
@12" below water @ 70%
Same spot as above 12" but at 100%
These lights are beast! Had a good talk with kessil @Macna 2016 hope they listen to some customer feedback (update the app )

I've been saying that. Lol

Great screen shots, good documentation. Good work.

Don't know why people think the AP700 is not strong enough with those huge reflectors it has. I guess spotlighting is the only way to show intensity in their minds.

So I just talked to apogee. The reef people on the internet have been saying you need to multiply your results by 1.32 for for "immersion correction". This has been the explanation for why the new 500 series sensors read so low. Now apogee is saying there is something called geometric correction depending how far your lights are from the sensor. If you throw this in it makes the "True Par" even lower then the read out. Apogee is saying this is the real PAR value and nobody does this. Basically said everyones PAR values are over stated. Now all sensors are useless, great.

Wow! So much for me getting a PAR Meteor, at least for now.

All I know is that my lights are awesome! Damn the doubters/haters. These things grow coral. Soon I'll post a one month update.

Just wondering, what is the advantage to getting an AP 700 instead of two 360?

It's nowhere near the same units. The AP700 uses both a giant dome optic plus a big reflector. The 360 has no reflector. This makes all the world of difference.

On top of what was stated u have complete control over color not just blue and white. Wifi built in. Higher PAR

Yes, I think this is what has given the AP700 the advantage over all other LEDs.

The light gets well blended because of the Dense Matrix Array and the single large fish eye lens over it.

The real magic though is the reflector. Seems basic, but the fact that the AP700 has no hotspots, and a very large coverage area shows its effect on the performance. The reflector pushes the light down into too the tank, and shapes it. This prevents light spilling out of the tank while ensuring every photon reaches the tank.

There are also more chips per LED, and more spectrum, they also added UV LEDs in the 380nm range.

I use the PAR meter readings as a relative value. If you measure the 'wrong' way, the same as everyone one else. Then just base your value as a % of their's, it will give you an idea of how far up or down you are. I think absolute values as not necessary. Your corals will tell you if you can turn it up or its too much.

Too bad the app only works on an ipad and the price is insane.

There is now an android version and the beta for IPhone is easily obtainable via Kessil.
