The LED Solaris Lamp PAR Comparison by PFO

As quoted, PFO states that the LEDs in their SOLARIS will last 50,000 hours. Quite a bit longer than halides!

As for the cube aquarium used, they were not ZeroEdge, but something close to 2 x 2 x 2.

 

Right, they will last 50,000 hours. Now how long will they old their intensity and spectrum? 50,000 hours is almost 11.5 years if you run the lights for 12 hours everyday. PFO hasn't had this fixture out or tested it long enough to determine that it will keep its intensity for 50,000 hours.

 

I have personal experience with this product. Both as a user and a dealer. I consider this product nothing short of amazing.

 

leds need to be replaced.. but every 11 years...

not 12 months.. just 132 months..

as they will loose only 30% of intensity after it.. like MH and T5 will in only 8 months..

 

PFO can only assume they will hold their intensity that long. Blue wavelength LED's weren't perfected until 1993 and white LED's until 1996. PFO would've had to do some quick research and studies to figure out that these bulbs need to be replaced every 11.5 years, otherwise it's just a guess.

 

they should use Philips leds.. so philips certify the lasting time.. not PFO..

and philips spoken about 50.000 hours on their luxeons HO leds.. like osram on the dragon..

a common led last 100-150.000 hours.. this HO leds only 50.000 and some only 25.000 (the 10W leds..)

so.. there is no history about this.. as the leds using now are "brand new" .. just only 1 year of life.. but i can trust them.. if not overheated they will last 50.000 hours as a led has nearly nothing that can breakdown..

 

For now it's cheaper to retrofit your own LED's. Buy the LED's and hook up the blues and the whites on separate dimmers and you have yourself a LED light for half the price.

 

surely..

i did it 5 years ago for my 1 liter nano :

just hard to find here in italy the HighOutput leds

 

Interesting debate, but what do you all think of the PAR comparison to halides? Does that surprise you?

Cool. What size aquariums do you have the light over? Do you have SPS in the aquarium? Where? Thanks for jumping in inwall.

 

some pic about the tank with the PFO light ?
tnx
