Prompt shipping, easy set up.

First, let me say that I have both the Vitamin D lamp (purchased in 2020), and the Fiji Sunlamp (purchased in July of this year). I can't say enough good things about the D lamp, and I have recommended it to so many people because it works. I'm not as big of a fan of the Fiji because while it does work, it works very slowly, and by the time I have a decent summer tan it will be sweater weather. In fairness, starting this process in July is why I'm not where I want to be, and it's far better that it works slowly than to get a bad burn. With that said, I have mixed feelings about the company over a customer service interaction regarding the Fiji. After a month of use, I thought it wasn't working, so I called them. The person I spoke to was very kind but did not offer any suggestions and just stated that if the bulbs turned on, they were working. This seemed a bit unhelpful, so I sent an email requesting more in-depth assistance. I got a response in minutes, which is rare these days, but it was not very helpful. In hindsight, I should have realized that since their devices are FDA approved, they need to make sure they're FDA compliant, and they can't really say much beyond the information they have already published. I later realized that there was some user error involved in how I was using the device, and I wanted them to know that the problem was me and not the device, so I sent a short email explaining that I was at fault and thanking them for their assistance. I felt a bit silly when I realized that the fault was mine, but I wanted them to know that they were not at fault. What bothered me, and why this is a 4 star rating instead of a 5 star rating, is that there has been no acknowledgement of that email to date, which is in stark contrast to the very speedy response the first time. What I ended up feeling was that I was a bother to them rather than a valued customer.

I just received my Sperti D Lamp, so I can't comment on whether it will raise my Vitamin D. However, the product appears to be high quality and arrived well packaged and in a short time. I am grateful there is a way to correct my deficiency and thank Sperti for designing an easy solution.

I knew this was going to be good when I saw it advertised on the Wise Traditions Facebook page. I love that I can build up Vitamin D levels even if my schedule doesn’t allow for me to be outside between 10am - 2pm. It’s really convenient since it only takes a few minutes per day, and doesn’t cause any sweating. I look forward to reaping the benefits of use over time! (The only reason my review isn’t the full 5 stars is because the lamp arrived with a dent on the corner, despite protective packaging.)

Device works good when used properly. Excellent color . I’d say dummy proof it. Put a zip tie pamphlet of “quick directions” to front of bulbs “grill” so user is more likely to look at it . You could put: warning not traditional tanning device: Put that schedule that’s in the directions With the 3 minutes this skin type .. so on and so forth . + 18 inches away (fingertip to elbow ) — I did give myself a kind of serious burn trying to tan “how I do traditionally in a tanning bed” Ie. 15 minutes. And that’s completely my fault / again “Dummy proof” it. Lol Over all excellent device I’m glad I purchased it. 🌞

We bought our Sperti Vitamin D Lamp in May 2025, and it is now July. It's working perfectly now, but it did take a few weeks for the light to come on when turning the unit on. We followed all of the instructions about how to prep the unit before starting and did it a few times. We even contacted support and they replied the same day. Excellent! I guess it just took a little more time than normal for the filmament to clear the bulbs before turning on. Not a big deal, but I just wanted to let others know not to worry. I did want to mention that I find the goggles very uncomfortable. They aren’t padded and so where they touch at the top of my nose and inner eye area is very sharp. My husband has no problem with them, however. My face is thin and bony so it could just be me. So I use a pair of goggles that came with my red light instead. My husband and I use it every other day, and along with taking Vitamin D3 and Vitamin K2 supplements and getting out in the afternoon sun when we can (we don't have much sun here), we're glad to know we have this unit to help keep our Vit D levels up. That's so important for our health! I'll know how it's doing with regard to our Vit D levels when I get more labs done later, but I have no doubt it's helping! So glad we made the purchase. Our health is worth it, especially as we are of an older generation!

Thought we’d give it a try! Living in Michigan, we see very little sun in the winter and that makes for long-dull days. We discovered Sperti and thought it was a wonderful idea. We take vitamin D supplements, and are happy to supplement with Sperti! It’s a handy unit and simple to use. We don’t really notice too much change or difference using it, but can’t imagine we’re supposed to “feel” vitamin D being absorbed. Only takes a few minutes a day and we’re happy with our little Sperti!

It arrived, must read fine print that it can take time to ship, but it’s here! It’s December and I have my Vit D test scheduled, then after bloodwork is done, I’ll start using my Sperti for 3 months. Next, will re-test my Vit D to track. So excited to get my Vit D back in range during winter. Yay!!
