A few weeks ago, I wrote about Seasonal Affective Disorder and the Daybreak Duo sunrise simulator that now helps me start my day on a brighter note. Over the last few weeks I’ve also been testing another another product from Philips Home Health Care, the goLITE BLU. My previous article goes into the science behind the product but, in summary, the wavelength of blue light it emits has been shown to suppress melatonin production in humans.


At 14 x 14 x3 cm (5.5 x 5.5 x 1 in.) and weighing in just 0.4 kg (14 oz), the goLITE stands in stark contrast to the huge light boxes of the past. The product is rechargeable and I found that I could easily get in six 30-minute sessions on a single charge. While the light is bright, I had no problem eating, reading or using my computer with the goLITE sitting off to one side shining in my peripheral vision (where it is supposed to be).

I try to use the goLITE BLU as early in the day as possible bu, on those mornings that breakfast ends up being a protein shake on the way to the office, I just slide the goLITE into my briefcase on the way out the door.

After using the product for a couple of weeks I did notice an improvement in my energy level and overall mood. Someone will undoubtedly point out that this could be a placebo effect and that’s certainly possible. But, in the end, I feel better and that’s all that matters to me.

    It’s probably a placebo effect but as long as you’re happy… That’s what matters.

    In studies they have measured the impact of various wavelengths on hormone levels, so I doubt it’s a placebo effect.
