Results: LED technology is not yet ready to displace linear fluorescent lamps as replacement light sources in recessed troffers for general interior lighting. The US Department of Energy (DOE) has published a new CALiPER Benchmark Report, presenting a comparison of T12 and T8 linear fluorescent Lamp with commercial available LED linear replacement lamps.
CALiPER testing addressed a range of standard lighting measures, including power usage, luminous flux, photometric distribution, source and luminaire efficacy, correlated color temperature (CCT), and color-rendering index (CRI) for the lamps tested separately and in troffers.
Key findings are:
LED linear replacements achieved higher fixture efficiencies than benchmark fluorescent configurations in CALiPER testing; however, low lumen output and efficacy limited their overall performance to levels significantly CALiPER testing at this time shows that LED technology is not yet ready to displace linear fluorescent lamps as replacement light sources in recessed troffers for general interior lighting.
