Just did a side by side comparison of the two models on the Philips.ch website. The only thing I found doing so is that the /02 has 315 lux vs 325 lux for the /01. Every other spec is exactly the same. Hope this link works on your computer: https://www.philips.ch/etc.... Otherwise, you may need to download the manuals and do a closer comparison of the specs.
