LED Optics Test

[wld1783]

The test fixture is our 24” LED Strip Kit custom assembled for Corbins Exotic Pets Pets in Buffalo Grove Illinois.

The Heatsink is a 24” x 8.46” from HeatsinkUSA. The LED strips are 6 XR-E Royal Blue/White and 4 XRE Royal Blue. The drivers are MeanWell 60-48D. The four Royal Blue strips are driven at full power (at 9 volts appx 580mA) in 2 parallel series of 12 LEDs. The other Royal Blue/White Strips are driven by a single MeanWell 60-48D adjusted to 750mA at 9Vdc



The drivers were adjusted and the input voltage was provided by a Radio Shack Enercell. Par was measured 24” above the fixture center mass and 24” centered but 12 “ to the side. The meter was an Quantum Flux Apogee meter MQ-200. Watts were measured with the common KillaWatt meter.

Wow, that is 100% more par measured with 70 degree optics compared to no optics!!! Great test, thanks for sharing!

[stryker]

100 percent more par...

[Macropora]

70 degree optics give the best PAR value. Thanks for sharing!!!

I was really surprised by the results....So much I ordered a couple thousand of the 70 optics as they rock.

Do you guys sell fixtures pre assembled?

[wld1783]

Do you guys sell fixtures pre assembled?

Yes Locally. Mostly for custom builds and Local Fish Stores

Shipping can be an issue as the heatsink is heavy and the LEDs are fragile...Reference the movie Cable Guy and UPS shipping.

Assembly is simple and less expensive if you follow our instructions. If you DIY you also have the option of fine tuning your fixture to the exact colour and PAR you want.. We do offer commercial fixtures. Here is a link. Reef Led Lights LED Fixtures. Please check on availability.
