The lamp is also suitable as a reading lamp. And I have a distance of lamp about book of about 75 cm were measured. Some of the lamp appears even almost too bright. Namely especially if the document consists of coated paper and therefore it is possible that a relatively strong reflection occurs and you are blinded! If one then considers the document to a different angle, however it comes. Also, I have rarely so which documents to read. Basically, however, it is also brighter than a 50W Halopar of Osram. That's what I have, however, already gotten used within a very short time. Even if it is sold as warm white, the light but appears compared to the halogen still quite white and is more reminiscent of a fluorescent tube. But to read that's perfectly fine.
With an ammeter, which is intended to provide very accurate readings according to the magazine c't, I have accurately measured 6.4 watts power consumption.
In addition, the lamp is no noise (humming, buzzing) or so of how someone wrote in the Advanced version with 7.5W. The Advanced I had, incidentally, also in view which has again 35 lumens more. I have not decided to do it because this lamp is very bright happiness!
