I&#x27;d love to see the something from Lumie [0] analysed&#x2F;reviewed like this in the UK. For instance the Lumie Vitamin L [1] is an LED version I&#x27;m interested in getting. I suffer for terrible migraine with aura [2] verging on chronic [3] that&#x27;s started to beat my maximum dose of beta blockers, so I&#x27;ll try anything!<p>[0] <a href="https:&#x2F;&#x2F;www.lumie.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.lumie.com&#x2F;</a><p>[1] <a href="https:&#x2F;&#x2F;www.amazon.co.uk&#x2F;Lumie-Vitamin-Lightbox-Effective-Therapy&#x2F;dp&#x2F;B073P2WNDS&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.amazon.co.uk&#x2F;Lumie-Vitamin-Lightbox-Effective-Th...</a><p>[2] <a href="https:&#x2F;&#x2F;www.migrainetrust.org&#x2F;about-migraine&#x2F;types-of-migraine&#x2F;migraine-with-aura&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.migrainetrust.org&#x2F;about-migraine&#x2F;types-of-migrai...</a><p>[3] <a href="https:&#x2F;&#x2F;www.migrainetrust.org&#x2F;about-migraine&#x2F;types-of-migraine&#x2F;chronic-migraine&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.migrainetrust.org&#x2F;about-migraine&#x2F;types-of-migrai...</a>

The conclusion about the UV diffuser isn&#x27;t quite right. It clearly preferentially attenuates around 365nm for example. Good article and solid conclusion though.

Can anyone tell how to measure the R1-R14 [0] values of a LED lamp? It seems like a sort of a Gretag-Macbeth [1] card is used. Can I use a photospectrometer [2]? I&#x27;d like to measure R9 [3] &amp; R13 myself.<p>[0] <a href="http:&#x2F;&#x2F;gc-lighting.com&#x2F;led-education&#x2F;lighting-guide&#x2F;" rel="nofollow">http:&#x2F;&#x2F;gc-lighting.com&#x2F;led-education&#x2F;lighting-guide&#x2F;</a><p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ColorChecker" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ColorChecker</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Spectrophotometry" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Spectrophotometry</a><p>[3] <a href="http:&#x2F;&#x2F;leapfroglighting.com&#x2F;why-the-led-r9-value-isnt-important&#x2F;" rel="nofollow">http:&#x2F;&#x2F;leapfroglighting.com&#x2F;why-the-led-r9-value-isnt-import...</a>

Oddly, the article neglects to mention the whole rationale for boosting the blue light in these kinds of therapy lamps: blue light (wavelengths in the low to mid 400 nm range) has the greatest effect on circadian rhythm.<p>Google &quot;blue light circadian&quot; for loads of data.

True(ish) sunlight lamps are freakin&#x27; expensive, no wonder 70$ is a scam.
