Very please with side effect, lol.
I purchased the 2-pack with the slight hope that using one in my &#34;reading&#34; lamp would improve my moderate SAAD depression.  And altho my suspicion that this single bulb would lack the degree of intensity necessary to be effective in that regard, I found that the very white light they emit *did* help relieve my eye strain while using my laptop.
