How many years has Philips Lighting Company been testing ALTO lamps to see if they pass TCLP, and what are the pass/fail ratios?
Philips has conducted hundreds of tests over the past 4 years. The EPA establishes the test and the statistical guidelines. Independent testing laboratories confirm these results, using the EPA’s TCLP protocol. The EPA’s SW846 procedure for statistical analysis confirms the confidence interval is well within the required guidelines.
