Abstract: Objective To investigate the application of white light emitting diode (LED) in magnetic resonance room, in order to resolve the damageable problem of incandescent lights under the high magnetic field. Methods The white LEDs and the incandescent lights were installed in MR room, the number of damaged lights was compared after 300 hours. Chi-square test was used for the statistical analysis. And the illuminance and 50 000 hours electricity consumption between LED and incandescent lights were calculated. Results The number of damaged LED and incandescent lights was 2 and 32, respectively and there was a significant difference (χ~2 =48.813 ,P =0.000). The illuminance of the LED and incandescent lights was 155 lx and 100 lX at the 0.75 m horizontal level and the 50 000 hours electricity consumption was 200 kW and 5000 kW, respectively. Conclusion It is feasible and a great advantage to use the white LEDs in MR room lighting.
