LED Lighting
We’ve been there since the beginning
OVERVIEW
Overview of LED lighting
•
What is an LED?
• Why are people moving away from traditional light sources?
1. 2013 – Phasing out and stop selling inefficient Diachronic & Halogen lights
2. 2013 to 2015 – Phasing out and banning any light that has a mercury content
such as Sodium, CFL etc.
3. LED’s are fast becoming a more efficient light source with over 100lm
per watt, estimated to get up to 208 lm/w.
4. Has a more stable white point stability.
5. Maintenance factor traditional used of 0.80 can be used as high as 0.95 on a
very good LED product.
BENEFITS
Key Benefits of LED lighting

BENEFITS
Key Issues of LED lighting found on the Market
•
Poor Quality LED’s proving to fail in short periods of time. (Colour
shifting, short life, short circuiting)
•
No control over temperature on LED’s
•
Low Quality and low MTBF electrical components
•
Products not fully tested but stamped with CE, EMC, UL when they
clearly don’t meet these standards
•
Manufacturers falsifying testing (if any) or approvals
•
No come back on products if from overseas. If they aren’t approved
and they cause a problem them your insurance will not pay out
•
No actual long life data on the products so you are taking their word
on the facts.
