Recessed Downlight
The single system LED hospital MRI fixture is designed and manufactured to
meet the specific requirements of the MRI room environment. This series
features an unique MRI barrier isolating the driver and other critical electronic
components.
APPLICATION - MRI HOSPITAL DOWNLIGHT
Medium ceiling height architectural applications requiring comfortable lighting
from a small aperture. The wide beam in many cases will replace a large
aperture compact fluorescent of almost twice the wattage. The narrow beam
with the optional 4100k color temperature LED will in many cases replace a 50
watt low voltage fixture.

Tested to IES #LM-79-08 standard testing Solid-State Lighting products and # LM-80-08 (measuring lumen maintenance). Peachtree uses the absolute photometry method at 25°c in
laboratory conditions, various operating factors can cause differences between laboratory data and actual field measurements.

Five Year limited Warranty
Unlike traditional light sources, LED's do not tend to fail catastrophically. Peachtree Lighting warrants the LED module and driver
assembly to be free of defects in material or workmanship for a period of three years from the date of purchase, and agrees to repair or
replace at the company's option, the “failed” component. Peachtree will replace a defective element without charge for labor. This
warranty does not cover labor to remove or replace the fixture back into the ceiling. This warranty excludes defects resulting from
improper installation, acts of God, fire, vandalism or civil disturbances. We must be notified in writing within 60 days of component failure.
An RGA must be requested and a sample must be sent to Peachtree Lighting for test and evaluation within the subsequent 30 days. The
RGA request must include proof of purchase. “Failure” is considered a non-operating LED. We reserve the right to change the standard
warranty period without prior written notice, without incurring obligation.
THE COMPANY SHALL NOT BE LIABLE FOR INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES.
The semiconductor manufacturing process, like any other lamp manufacturing process, brings about variations in output to the right and to the left of mid
point of the standard, regarding color and other attributes. Peachtree Lighting has investigated and considered most of all of the available procedures to
control visible color shift in solid state lighting. At this time, in our opinion, “binning” (grouping similar appearing chip modules) seems to be the most
consistent and reliable method. Peachtree products are color controlled using standard ANSI binning, which will be suitable for most general Architectural
installations. When necessary, because of the critical color application, please contact the factory for tighter binning including a “single 3 step MacAdam
ellipse”.
* Luminous Flux and Delivered Lumens
At the heart of most white LED's is a semiconductor chip made of nitride-based materials. The chip is positioned on top of the cathode lead. Applying volts
across this device makes the chip emit blue light. Passing the light through a yellow phosphor yields white light. The LED is therefore a relatively small
device emitting visible light either from the sides, bottom or both sides and bottom depending upon the very small lens and or small reflector incorporated
onto the chip assembly. Calculating light output should rightly be conducted considering the whole assembly.
You can not directly compare LED's and incandescent because the spectra are different. LED efficiency is measured with short burst of power. A 100%
efficient incandescent would put out about 200 lumens per watt. A typical white LED is deficient in some of the longer and also shorter wavelengths to which
the eye isn't very sensitive, (so the corresponding figure for a 100% efficient LED is around 325 lumens per watt) There are differences between what the eye
sees and the meters read. LED's are different. IESNA has developed special LED testing methods. Peachtree Lighting data is in accordance with LM-79-08
& LM-80-08 Please use caution when comparing LED data to data from other lamp sources.
