CSA Summary Report of Competitive 4 ft LED Tube Lamps
The purpose of BramalLED Inc. to involve CSA, an independent third party testing agency is to compare and evaluate the total power consumption and light variations of various 4ft LED lamps with various fluorescent ballast having low, normal and high ballast factors. Each LED lamp is tested on 5 different ballasts and measured for total power consumption and light output. The measurements are plotted on a line graph for each model. Minor deviation in power consumption makes it possible to calculate an accurate ROI (return on investment). Also having a consistent light output across different ballasts is very important because of the tremendous variations of ballasts types on the market today. It is very uncommon for a building to have all the same fluorescent ballasts due to scheduled replacements, discontinued models, and upgraded versions. It is essential to have consistent light output on different types of ballasts so light levels can be held to desired standards and do not fluctuate throughout the building.
Power variation and light output variation are of the greatest performance concern with respect to lighting quality. The Luxul and Philips lamps showed the greatest power variation of the tested product.
Two Luxul lamps failed when applied to the GE432 ULTRA electronic ballast. The Philips lamp consumed highest power (30.7W) when applied to the GE432 ULTRA ballast. Bramal and Khumo lamps performed with the most consistent power output. The Khumo lamp had a power variation of 6.9 watts. The Bramal lamp showed the least variation of 3.4W across all the tested ballasts. Power variation directly correlates to lumen variation. The Luxul lamp showed a lumen deviation of 1239 lumens with the lowest lumen output of 1678.5 lumens average. The Khumo lamp showed a deviation of 924 lumens. The Bramal lamp averaged 1857.4 lumens (rating is 1850L) while maintaining the lowest deviation of 387 lumens.

Test Procedure:
The samples were evaluated for photometric and electrical characteristics using an integrating sphere, located in purpose-built, temperature and humidity-controlled, draft free environments.
The integrating sphere is by Labsphere which exhibits a “4π geometry” configuration according to IES LM-79-08 and is applicable for all types of LED products (directional and non-directional light projections). Its spectroradiometer is an array-type detector manufactured and calibrated by Labsphere.
The integrating sphere uses self-absorption correction to eliminate errors due to mismatches between the standard reference lamp and the test samples being measured. The auxiliary lamp used to perform this task is a halogen type lamp powered by a calibrated Lamp Power Supply manufactured and calibrated by Labsphere. Ambient temperature (for photometric analysis) is measured using a “J-Type” thermocouple located inside the integrating sphere at the same height as the sample under test and not more than 1 meter in horizontal distance away from the sample. The thermocouple is located behind the baffle of the photo detector in order to eliminate any direct optical radiation from the sample under test.
Luminaire Stabilization.
The samples were placed inside the integrating sphere and powered by a regulated and conditioned Voltage alternating current supply. The Luminous Flux and electrical power measurements contained in this report are the numeric averages of the three readings upon which stabilization is verified.
