The color temperature and pattern of light emission are very similar to an incandescent bulb. The three-pack price is an excellent value, assuming they have a similar lifetime to other LED bulbs.However, you should be aware that these bulbs do NOT produce the "glowing filament" effect that you see in "Edison-style" incandescent bulbs. You should not expect gently glowing orange filaments. In order to achieve that effect, you need a bulb that can be dimmed...and these bulbs CANNOT be dimmed! You can see the filaments, but they are blinding to look at! These bulbs glow like regular 40W bulbs, and you really need some kind of lamp shade, because the direct light is rather harsh. I am still shopping for dimmable "Edison" bulbs to produce that glowing filament effect. ### ⭐⭐⭐⭐⭐ All are stunningly beautiful and make a tremendous amount of light *by P***T on Reviewed in the United States on November 6, 2014* I actually purchased four of the AriusTek bulbs - two of the 4W and two of the 6W. All are stunningly beautiful and make a tremendous amount of light. I have no argument with their 40W and 60W comparisons in the amount of light produced. These are much brighter than the dimly-glowing incandescent Edison bulbs but they're perfect for the pendant lights over our kitchen island. Excellent seller who followed-up via email to ensure that we liked the product. Great lights at a fair price and I expect to purchase more bulbs from AriusTek in the future as I continue to replace other incandescent bulbs throughout my house. ### ⭐⭐⭐ S21 Beautiful but bad strobe effect *by A***R on Reviewed in the United States on September 18, 2015* I've only had these for a few days. The vintage style filament looks great, and the 40W equivalent matches the spectrum and appears brighter than the 60W bulbs they replaced.For the above, I'm keeping 3 stars. If this is only supplementary lighting, you'll love these.Unfortunately the 120 hz flicker/strobe is worse than any other LED light I've ever seen. Using these as the primary lighting source, fast-moving objects leave a strobe effect. Just darting my eyes can make me feel dizzy.I've included a picture from my cellphone where the strobe is very clearly seen. For comparison, it's barely visible on my Philips LED lights and has very narrow bands (high frequency pwm for you more technical people).Unfortunately, the manufacturer cut a few corners here.. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/18822636-ariustek-s21-5w-vintage-edison-led-filament-light-bulb-warm](https://www.desertcart.us/products/18822636-ariustek-s21-5w-vintage-edison-led-filament-light-bulb-warm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
