Benefits of Magnetic Ballast
1.  Low price with long lasting life up to 20 years, when comparing to electronic type with 5 years life.  Some electronic types cannot withstand power surge and yield shorter life span.  This life of magnetic ballast will help reduce maintenance cost.
2.  Electronic ballasts are installed at the site without a constant power supply, will shorthen life of the ballast itself.
3.  Harmonic interference of electronic ballast might disrupt the IT, communication and sensitive electronic device (e.g. in Medical Operation Room)
4.  Electronic ballasts are installed at high temperature area may shorthen usage life.

Advantages of PSJ Energy Save Equipments

1.  Energy saving up to 50%
2.  Co-exist with current installed lighting system and equipments
3.  Illuminance controllable as needed
4.  Prolong life span of the lamp over 100%.  Reduce maintenance and replacement cost for high-ceiling installation.
5.  Easy to install, low maintenance cost
6.  Accredited and accepted by high credential orgainzation, ISO 9001/2008 and CE Standard.

Note:  The comparison was based on standard price list (ex-VAT 7%) of the products at the same level of standards and was referable in terms of technical specifications.
