Which would be better

Two Onyx units OR three A51s over a 2x4 table?


The onyx are $350 apiece, and the A51's are $250 apiece (bulk rate), so price diff is $50 more for the 3 A51s.

 

3 would be more optimal for lighting right? 750 for 3 sounds like a deal man

 

Sounds like you're talking rw 75s. The RWs will run cooler but I would think it would be more accurate to say 2-Rw 75s equals to one onyx just with a wider foot print. Or one RW-150 to one onyx. You're talking 225w a51 vs 440 or so onyx. I'd say 300w of a51 would be more comparable.

 

2-600s will out yield them poopers anyday


LEDs.....pfffft

 

Ah come on CC, don't .issing: on their party. (though you are right):lol1:

But why drive the old Cadillac if you can afford the new Benz no problem? LOL 1200w of quality LED would murder that ~1300w hps. Just sayin'.... I could care less if start up was 5x more. Will pay itself off no doubt.

 

My bad my original post was muddy. Yeah I was thinkin the RW-75 but looking again three of them are def not comp to the 2 Onyx units. I was just wondering because I know one issue with the LED lights ATM is footprint, so I thought more lights = bigger footprint, so if I got 4 RW-75's per 2x4 table (flower only BTW) I could spread that light out a lot. If A51 would do anything with the $239 price, it might be an option. If I could get them for $190 each, that $760 per table vs $700 for the Onyx.


I'm gonna run the LED to flower and see what I get. I'm going for the prom queen at this dance CC!


I know your a bag-the-fat-drunk-girl who you know will put out kinda guy. And I respect that. Been there, doing that. Edit - Light-wise. This is def NOT a reference to the beautiful and mysterious Mrs. Farmer or Mrs. Crete or whatever (Mr. Crete? :LOL.

 

What it boils down to between area 51 and onyx is this. A51 spreads the light a little more where as onyx is a little more concentrated. Onyx is the best bang for your buck other than diy, a51 is more efficient as far as light output per watt. Hence the cooler operation. A51 uses more drivers so clusters are independent of others whereas onyx is the single meanwell. So if one thing goes wrong the whole light goes. Though they use quality everything to failure should be fairly low and no reports I've seen on the forums so far. Onyx drivers are higher quality than a51. It's like buying just about anything. Nothing is perfect and they all have some pros and cons. I have my PPF measurements for the rw-150 and I'm sure RapidLED will have no issues providing you data. If up front cost is your main driver, onyx. If it's cheaper operation cost over the long haul A51. That's my assessment. Both are pretty top notch.


Oh and forgot warranties. Look at what both companies have to offer. Though keep in mind also A51 is like the county store to Wal-Mart. Rapid is a full fledge corporation while a51 is a personal small business. Which hints to pricing differences. Rapid ad deeper pockets for bulk builds.

 

And the fat girl, prom queen, moped analogies are killing me over here. Lol Better than my car one that's for damn sure. Haha

 

I'm loving my A51 RW75's in my 2'x4' closet. And temps are stellar. Can't go wrong either way if heat isnt an issue.

 

Not sure what the heat reduction is, but I noticed the Onyx uses a separate power supply that can be kept in another room. How much heat does the power supply produce, enough to warrant keeping them in a separate area?


For me the LEDs are the solution for areas with no AC or even a spot in the HPS rooms where tying in another vented hood would be too much trouble. If there's an unused corner in a room loaded with co2 I see it as wasted space. A couple more plants flowered out and the investment's more than covered.


Every dollar spent on anything in the process is an investment. And as long as the return reasonably exceeds the investment then it's justified.


That's just the business man peaking through the bong hits.

It's not because the supply is hot. It's too make the light you hang a little lighter and to keep that heat away from the diodes. Heat reduces light output. Also, ease of service. But main reason because that was the original casing design for the onyx which started as an aquarium light. So mainly the weight. The onyx horticultural lights came about 2 years after the dimmable aquarium light.

 

While we're on the subject of analogies. I was just thinking that converting CC over to LED is about as likely as the fat girl getting picked first in the dodge ball game.:roffl: Just fuckin with ya CC.

I figured it was a design carry over. I didn't think the power supply would have enough resistance to create a lot of heat.

wow I'm wiring for what would be the equivalent of an 8K flower room. Damn onyx units draw 9.7 amps! Burning two of those to replace a 1k HPS eats up twice the amperage? Jesus I will need a 20 amp circuit for each 2x4 table.
