I need an alarm that makes no sound at all . Is there an option to turn off all sound?

The Sonic Bomb has a pad that vibrates under your pillow. Since my wake-light only lasted 2 years, I got the Bomb, because I didn’t hear the alarm clock. I prefer the Wake-up light, but you can’t replace the bulb. I am not paying $100 every time the bulb dies in 2 to 3 years.

what are the 5 choices of sounds?

Loud bird chirping, (rainforest maybe?) birds screeching and calls, music with birds, piano music, and the distant sound of waves under seagulls

Is the light very blue from the LED? I'm thinking of the blue-ish tinted "white" LED christmas lights... I prefer the warmer colors!

The LED light is not blue or white... It's a sort of orange color. Very warm and pleasant. You can also adjust the intensity of the LED light to make it very soft so you won't notice it in the dark. Perfect for people that prefer to sleep in a completely dark room, like me. But you can still see the time, even with the soft LED settings.

Is it worth the extra money to buy this over the HF3470?

Hey BenjaminThere is a side-by-side comparison of the various lamps Philips makes at the end of the listing for the HF3470. It looks like it boils down to this: The HF3470 has a replaceable bulb (what that entails, I couldn't tell you. It looks like the HF3520 must be a "forever" bulb). The HF 3470 has a "sunrise simulation" which I dig, and helps me wake up more naturally, which is what I bought the product for in the first place, so that was important to me, but is it for you? Lastly, the HF3470 has 2 sound simulations whereas the HF3520 has 5. I wouldn't call that particular facet a deal breaker. It looks to boil down to the idea of the sunrise simulation and is that worth roughly $60 for you? Happy shopping.
