e US Department of Energy (DOE) has published its latest Caliper Report, Series 16, which involved the testing of LED-based BR30 and R30 lamps. The report indicates that the13 LED products tested could be effective replacements for the bulbs they were benchmarked against, one 65W incandescent BR30, one 15W CFL R30, and one 16W CFL BR30.
The performance of the Series 16 products can be summarized as follows:
•
T
he lumen output of many of the products was equivalent to 65W or 75W incandescent BR30/R30 lamps. All of the products emitted between 460 and 860 lm, which is within the typical range of conventional BR30 and R30 lamps.
•
A
ll of the Series 16 LED products exceeded 51 lm/W in efficacy, which is greater than the Energy Star criterion of 45 lm/W (Fig. 1). However, the two most efficacious products also had CCTs above 5000K.
•
T
h
e Series 16 LED BR30/R30 lamps had luminous intensity distributions ranging from very narrow to very wide.
•
T
en of the LED products had a nominal CCT of 2700K or 3000K, which matches typical incandescent and CFL BR30/R30 lamps.
•
T
he power factor of the lamps was considerably better than previously tested LED BR30/R30 lamps, with 12 LED products exceeding the Energy Star minimum requirement of 0.70 at >
5
W
.
In general, the results showed substantial improvement versus earlier Caliper testing of similar products. The report also indicates the need for a broader range of LED lamps within product families in terms of lumen output and distribution type. It also questions the adequacy of existing reflector lamp categories for LED products.
