Introduction
Located just outside of Vancouver BC, product design, testing, production, powder coating & innovations are all done within our 31,000 sq ft facility. Our specification-grade architectural lighting products have matured over the years to now include a multitude of Downlights, Recessed Multiples, Pendant Multiples, Architectural Cylinders and an ever expanding array of LED products.
With pride & passion, Dasal continues to evolve by closely studying and thoroughly understanding how technology is shaping the future of lighting. Coupling our knowledge with our passion to make it better, along with input from our discerning clients, we continue exceeding industry standards to ensure years of reliability and performance in all that we do.
A constant force behind all Dasal product is our team of dedicated professionals. A culture enriched with creativity, intelligent customer service, quality control, plus a never ending quest to exceed expectations, are the spirit of our team

Knowing that……
How does one effectively use LED’s?
Single Point LED’s
• Visually Appealing
• Optically easier to control
Vela & Draco luminaires
Ultra Compact Series
• Smaller Luminaire
• Easier to Thermally manage
Multi Point LED’s as Downlights ?
• Collimator approach can cause multiple
shadows
• Visually Unappealing
• LED’s from multiple bins resulting in various color temperatures from LED to LED
• Using phosphor converted white LEDs necessitates usage of individual collimators over each LED and a dedicated design
• If the LED count decreases because of increasing LED efficiency then a new optical design will be necessary for the luminaire. It is not “future proof”.
..If multi Point LED’s are not the answer for Higher Lumen output downlights, what is……..?
Introducing the Xicato Spot Module
Cold PhosphorMaximizing Robust Life
“Cold Phosphor Technology” results in higher efficacies and lifetime of both LED and phosphor
o Reduces heat due to photon recycling 360o heat conduction
o All surfaces thermally coupledo Heat conduction from top and bottom of
device Results in a uniquely miniaturised module
with relatively low heat sinking demands
360o thermal Path
700ma Heat Sink
The design of the Xicato Spot Module tackles these challenges and results in a lighting solution without compromises
Patent pending internal optical mixing cavity (allowing reduction of LED count over time)
Patent pending thermal design
Patent pending “Cold Phosphor Technology”
Ability to use full distribution of production LEDs while maintaining consistent color and flux performance (product – product and over temperature and lifetime)
Remember this ?

Color Maintenance
• Each set of points represents a different module under test. • Multiple data points represent different HTOL test time intervals
• Color Maintenance after 5Khours• LM-80 test 85o C• 4000K and 2700K similar

Field Replaceable
Every DASAL LED luminaire undergoes
thorough thermal testing and performance reviews,
including LM79 testing
The Xicato Spot Module integrated into any DASAL luminaire can be replaced by a future
version with a different LED count without necessitating any changes
to the optics and uniformity of the luminaire.
