What you think about this lamp?

duralamp.at is a legit website, hosted in Austria. Dot at is the Austrian top level domain. Virustotal.com shows the site, and the pdf as clean. I don't know enough about lighting to be helpful with the specs.
 
Why do you like it over the many other options out there?
it cost about 4€ and i think 400w hps whitout cooltube heats my room so hot! I just want to know about these spectrums. Is it really dual spectrum lamp and should it works for vegging and flowering?

Well for a start lumen output sucks really bad , and the spectrum of it blows chunks .
Overall it's a piece of shit.

Seriously though forget that bulb, heat issue's.....drop your wattage or better yet buy a cool tube. And just veg and flower with a hps.
