Benefits of the HF3510 and HF3520
These 'alarm lamps' are pretty much revolutionizing the way we get up in a morning -- where they have been independently clinically proven in numerous studies (along with being officially backed by the National Sleep Foundation along with thousands of users) to make it a lot 'easier' to get out of bed, improve sleep quality as well as increase alertness and energy levels for throughout the day (pretty awesome!).

The Differences Between the HF3510 and HF3520
The HF3510 & HF3520 model actually share a lot in common -- obviously such as its sleek & modern looking design that has been well crafted with clever features such as its touch-user interface for you to select specific settings (with additional buttons round its rim) along with the 'auto-dimming' clock-face (where when there is no light, the clock automatically dims & when there is sufficient light in the room it gets brighter, very clever -- see video below).
They also both have a built in FM radio for you to either use casually or as your actual alarm noise (as said which will gradually get louder and louder within a 90 second period, to wake you up). Also, they have a clever 'Easy-to-Use' snooze system installed where you literally just to have to hit anywhere on the lamp and you will get an extra 9 minutes sleep. Each model also obviously has the dawn and dusk simulation (some models don't come with the latter, for helping you get to sleep) integrated too.
Really, the only main differences comes in the fact that the HF3520 has an additional 2 natural sounds to wake up to (so five altogether for the HF3520 and three for the HF3510) as well as you being able to adjust the period of time (from 20 to 40 minutes) which the light intensity levels take place, giving you room to experiment as to which works best & is most optimal for you (whereas with the HF3510, it is just fixed at 30 minutes).
Specifications & Details

They have the same type of bulb fitted a Philips lumilled Luxeon rebel type which has been specifically designed to be 'long-lasting' (approximately 20 years of use, around 4,000 + hours of constant use), so you won't obviously have to go out to keep replacing these.
When purchased new, they are immediately backed by a industry leading 24 month period that covers both parts and labour (Philips are by the far best brand in terms of quality & durability for these 'wake-up light- based products, I personally wouldn't even consider anything else).
They are of course certified as very safe to use and are UV (ultra-violet) free.
Conclusion: Which Wake-UP Light Should I Buy -- the HF3510 or HF3520?
As you can see the HF3520 is a slight upgrade to the HF3510, however there is marginal difference between the models really (unless you are keen to experiment, I would be personally, go for the HF3520 -- if not you won't be missing out on anything by opting for the HF3510). Although, they are more expensive than your traditional digital alarm clock, the benefits they offer (e.g. more energy, better sleep quality etc. which are all pretty much priceless qualities in life) far out weigh those types and are in all very crafted. A really awesome invention.
