Blue light and eye damage: Does anyone know the frequency # of this product?
2000108
No, it's not a bad thing. Yes it's lower than 500nm but that doesn't mean it's not safe. This blue light is similar in wavelength to the sky itself, so it's like looking at blue sky (though NOT looking at the sun of course). I would be (and am) far happier using a lower power blue light than a high power white light which also contains the same blue wavelengths. You probably know that sunlight contains all the colors of the rainbow so it's best to think of this blue light as a safe kind of sunlight with all the other colors taken out because they're not needed. At night, for good sleep, you want to BLOCK as much blue light as possible so that your melatonin (the sleep hormone) ISN'T suppressed. The best way to do that, if you don't want to go back to evenings with only candles for light and no televisions or computers, is to wear glasses like these Orange glasses for the last 2-3 hours before you go to bed. They look silly but if you're having problems with energy/sleep they can have a miraculous effect literally overnight. Nothing, and I mean nothing, has affected my sleep as much. Not expensive beds, or prescription sleeping pills, or exercise. Nothing. They are worth their weight in gold :-) Does that help? I hope so.

Thanks for your prompt reply - I actually already own this item! After years of use, the bulb has burned out and I'm tying to determine if it can be replaced. I'm disappointed with the short lifespan of the item, but I wasn't necessarily disappointed with the performance. With the proper room placement, focus of the lens, and assurance that there was no light polution, the item performed quite well. Until it died, of course!

Yes it is an error, it is the Blue Beta with remove. I love it, however it does not work in indoor ranges with florescent lights. I tried to supply a strong LED light source to defeat the fluorescents.... does not work.... Outdoor it is awesome. The cryptic menu structure and instructions takes a learning curve. It is compact and folds up nice and should be durable. Not sure what the price is now but it was on sale when I bought it.

It's decent with the blue light blocking, not the best. In hindsight I should have ponied up and bought the more expensive ones since I am on the computer about 12 hours a day. The sleep factor, I'm unsure as I didn't put emphasis on that when I bought them nor have I tracked it. I hope this helps.

If you find out, please post. I tried chatting with someone at Philips instead of calling and he only pointed me to this quote at http://www.sadlightshop.com/lighttherapy/philips-golite-blu/ "Bluewave: Advanced blue LED technology Philips HF3330 Golite BLU provides the specific spectrum of light our bodies respond to. Advanced diffusion optics and less intense than 10,000-lux white light provide a soft, even light while the wider treatment field for flexibility. " Not official Philips info nor can I figure out whether it's &lt;=&gt; 10,000 LUX based on the wording. I'll give them a call next week when I can but it sounds to me as if they deliberately have left out this information for a reason, perhaps to avoid being classified as a medical device (?). I really don't know but it is suspicious and I want to be assured the time and money I invest in this treatment is worth it and not just a placebo effect.

OMG! Too Much! In the instructions it says only one light per (25 min) session and to let your skin heal for 24 hours in between sessions. Since I have acne and rosacia, I use the blue light primarily, then I use the red light for collagen production, every third night. I don't have hyerpigmentation anymore, so I do not use the aqua light. More is not prudent with this technology. You can create more damage by inducing inflammation. Be patient and use one light per night. The acne results you will see within a few nights... The other two lights, you will see beginning results around a month (on average and based on other customers and friends). Good Luck! OMG! Too Much!

Two flashing light eyes. The first set I bought, the eyes didn't work - I contacted the company directly and they sent a package out free of charge with working eyes.

I am not sure of the exact frequency, but the light is bluish, much more so than an incandescent bulb. I have a strip installed next to the warm yellow colored LED strip and there is a marked contrast between the two.If you want, I can email you a photo of the two operating together.

I didnt read anything in the product description that said anything about bluerays. I bought these to help my eyes from getting tired from the flourescent lighting in my office at work. So in that regard, they work for me.

Hmmmm... All I can suggest is checking Optoma Technology data base at http://www.optomausa.com/support/tech-support/knowledge-base.aspx or if you have any questions regarding the RMA policy or are in need of technical support, please call Optoma's toll free number at 1-888-887-5001.

In particular NO BLUE LIGHTS! The bane of our e-existence. Blue lights. Argh. Red doesn't wreck night vision - one of the reasons it's not so annoying (except when you'd wish there were none). But blue demands your attention. Now! Really? Now! Ack! Like the new(ish) blue headlights wreck your night vision as well. No Blue Leds!

The light from my unit is blue. Can't say it's blue laser, but would think so

I purchased the 46EX645, this model is an LED 240 Hz model. If you have a Sony blue ray player you will be pleasantly surprised to see how the two items work together automatically. I continue to highly recommend it.

Stan, Sorry I don't have the quantitative data available such that I refer you to the manufacturer for it. Qualitatively, however, mine is doing a good job. Uncharacteristically we had a week of clouds and rain lately. As a result, the brightness and duration was impaired somewhat but at 0530 hours of the morning of the fifth day there was still a glow emitting from the 20-or-so LEDs. Now that we're past the autumnal equinox I expect some diminishment but we're more than likely to have clear than obscured skies at my altitude (~6700 ft) and latitude (~ 41degrees N) during the upcoming winter period.

Thanks for the info. I hope to goodness that the lamp life is not 3,000hrs! I've been waiting years to buy a projector that doesn't require rip-off bulb replacements. My own HS201 is on a UPS truck at this very moment, waiting to be delivered to my house...

I gave this as a gift to my 8 year-old nephew. In the meantime, he developed some serious eye problems & has been unable to use his headphones to play any computer games or his iPod because he can no longer see the screen because of a patch over 1 eye & instructions from the ophthalmologist to stop watching TV & using all computer screens until his eye heals for 6 mos. Apparently, this is an increasing problem for children who play a lot of games for hours. They're developing eye strain and it's pulling on their retinas. I wish I had a answer for you: but I did want to pass on that piece of info as a warning in case your child is using the headphones for this reason. I gave this as a gift to my 8 year-old nephew.

Good question; maybe would be clearer if you asked "color" temperature. I would expect about 5000K otherwise people would be complaining about blue garbage light.
