RGB Blue LED + Phosphor
Pros:• Tunable CCT,
colors• Any color
possible
Cons:• Difficult to
control• Low CRI (<50)• Lowest LPW
efficacy
Pros:• Single LED type• Easy to control• Easy secondary
optics• Good CRI (~90)
Cons:• Good efficacy
Pros:• Highest
efficacy (+20-30% v. blue + phos*)
• Highest CRI (>90)
Cons:• Complicated
to control
Four Ways To Produce White Light with LEDs
Blue LED + “Remote” Phosphor
+
“BSY” + Red
Pros:• +5-10%
efficacy v. blue + phos
• Good CRI (~82)
• Easy to control
Cons:• High cost due
to complex LED binning
• Rigid form factors* Achievable system efficacy @3000K, varies somewhat by application

What is Cree TrueWhite® Technology?
True White™ LED Lighting – 44 Total Watts
• Cree unique advantage based on mature and patented technology from Cree:
– A better way to generate white light that utilizes a patented mixture of unsaturated yellow and saturated red LEDs.
– No compromise between energy efficiency and light quality.
– Proprietary optics yield uniform, comfortable appearance. Pixelation and direct view of LEDs is eliminated.

Cree Modules Value During Product Re-Design
•Protects investment in most expensive system components
Future Leveraged Technology
SAME lumens SAME equivalency
SAME form factor SAME brackets
SAME optics SAME reflectors
LOWER power LONGER lifetime
LOWER price MORE margin
New generations of Cree Modules will provide:
Unique Value of Cree LED Modules
Overcoming the Time Factor:
• ONE light source design that protects your investment in product design
– Form factor, light output, optics, electrical
• Open ecosystem
– Third-party driver recommendations and no proprietary cables
• The Faster we can get our customers to the market, the faster we all win!

What is Sunset Dimming?
Sunset Dimming accurately simulates the dimming profile of an incandescent lamp using LEDs
– Follows the black body line from 2700K to 1800K
– At 1800K similar in color as candle light, sunset, and sunrise
– Color changes naturally just as an incandescent Light Bulb
• First Lighting Solution to replace the incandescent bulb with no compromises!
– Quality of Light 90+ CRI
– Efficiency of LED 95 LPW
– Dimming of incandescent light bulb
– Full family of Lumen values
No-Compromise Dim-To-Warm: Sunset Dimming
• Smooth transition from 2700K to 1800K• High CRI throughout dimming• Can dim to 1% brightness• TRIAC dimmer compatibility
Dimming experience similar to incandescent
• >80% energy savings vs incandescent• Stays efficient while dimmed• 50x longer lifetime
Brings all the benefits of LED technology
• Available in 4 lumen levels• Same form factor & ecosystem• White appearance when off
Delivered through LMH2 platform
Cree LED Modules: Two Dimming Choices
WhiteLight
Maintains consistent color across entire dimming range
Keeps colors natural
Wide dimming range with smooth transitions
Sunset
Provides rich, warm dimming from 2700K down to 1800K
Creates an intimate atmosphere.
