It's a really good bulb, truly what you'd call a dual-spectrum one. I'm very impressed with the results. Would it also be suitable outdoors in summer?
Translated from Spanish
Es una muy buena bombilla, lo que se describe como mixta de verdad. Estoy muy impresionado con los resultados. ¿Sería apta también para exterior en verano?

My plants have grown hugely with this light; in just a few days they show a vigor I hadn't seen before. It's fantastic for the entire grow cycle. Cheap and effective like few others. I'm really happy!

Frankly, it's excellent. My plants loved it, growth is very fast and flowering... magnificent! Unbeatable value for money. A really great dual spectrum bulb, I recommend it without hesitation.

I bought it for veg and a couple of weeks of flowering (and as a spare if the one I have just for flowering burns out), so far it's working great, the girls are doing much better than with the previous bulb, but I also have to mention that a few other small things changed, so I can't claim it's just down to the light, but personally, I think it's worth it, even though it's a bit pricey let's see how long its lifespan is now :)
Translated from Spanish
La he comprado para crecimiento y un par de semanas de flora (y de repuesto si se me quema la que tengo solo para floracion), de momento va perfecta, las niñas mucho mejor que con la bombilla anterior, pero tambien he de mensionar que han cambiado algunas otras cosillas, con lo cual no puedo afirmar que se deba solo a la luz, pero personalmente, creo que merece la pena, a pesar de que es un poco carilla a ver ahora cuando tiene de vida util :)
