H4 LED Downlight Series 2nd Generation –
LED Light Engines
The Halo H4 LED is a family of 4” aperture recessed downlights with
H457 series housings designed for use with Halo EL406 Series LED
Light Engines and compatible TL4 and TLS4 Series LED trims. Halo
H4 LED housings have integral LED drivers that offer dimming as a
standard feature.
Halo H4 LED is a three part system: EL406 Light Engines, with TL4/
TLS4 trims and H457 housings. H4 LED 2nd Generation features 90
CRI color rendering index and offers a superior optical design that
yields productive beam lumens, good cutoff and low glare.
MECHANICAL
(A) Upper Heat Sink
• Durable extruded aluminum
construction.
• Conducts heat away from the
LED keeping the junction
temperatures below specified
maximums, even when installed
in insulated ceiling environments.
(B) Lower Heat Sink
• Durable die-cast aluminum
construction.
• Precision keyed flange designed
to lock with matching keyed slots
in H4 trim rings.
• Works in conjunction with
the upper heat sink for heat
conduction away from the LED
MOUNTING
(C) Friction Blades
• Precision formed stainless steel
spring blades provide retention of
the EL406 series of light engines
in the H457 series housings.
• Friction blade design allows the
light engine to be installed in any
position within the housing
aperture (360 degrees).
ELECTRICAL
(D) LED Connection
• LED connector is non-screw
base offering easy installation
with the H457 Series housings.
• LED connector is compliant
with high-efficacy luminaire code
requirements as a non-screw
base socket.
• Separate grounding cable
included on the module for
attachment to the housing during
installation.
COLOR SPECIFICATION &
QUALITY STANDARDS
• Halo employs a tight chromaticity
specification and LED color
binning process to ensure LED
color uniformity, sustainable
Color Rendering Index (CRI) and
Correlated Color Temperature
(CCT) consistency over the useful
life of the LED
• Halo H4 LED chromaticity
specification is 3SDCM initial
and 5SDCM at rated life, which
exceeds ENERGY STAR
®
SSL
color standards (as per ANSI
78.377-2008).
• Every Halo LED Module is quality
tested and performance measured
on the production line, and
serialized to register lumens,
wattage, CRI and CCT
• Halo LED’s serialized testing and
measurement process further
ensures color and lumen
consistency to meet stringent
Cooper Lighting specifications
and exceed ENERGY STAR
®
SSL
standards
• Halo LED Modules and light
engines include color designation
in the model number
QUALIFICATION
• Halo LED offers the choice of four
correlated color temperatures:
2700ºK, 3000ºK, 3500ºK, 4000ºK
• 90 CRI
• LED package consisting of an
engineered array of multiple LEDs
to create one virtual source, for a
productive “cone of light”
• Designed for interchangeable trim
choices, with selection from
multiple reflector, baffle, and lens
trim options
• H4 LED Light Engines are
ENERGY STAR
®
Qualified as used
with designated LED trims*
• Can be used to meet State of
California Title 24, and
International Energy Conservation
Code – IECC, High Efficacy
requirements when used with
designated LED trims*
• LED emits no ultraviolet and only
minimal infrared wavelengths
• ROHS compliant
