I have waited patiently for this delivery. Unfortunately, I received white light bulbs that I could have found locally. These are worthless for my purpose.Update: Today I was starting to put these bulbs in a storage drawer when my husband asked if I had tried one in a lamp. I had not. So, he put it in a lamp and turned it on to see a beautiful green glow. Just what I had wanted when I ordered them! Even though they are white bulbs, they glow green when turned on! I am very happy with this purchase. ### ⭐⭐⭐⭐ Bulbs are not colored only the light! *by M***A on Reviewed in the United States on December 2, 2019* This are perfect for our holiday decorating outside (put them in our garage sconces). I guess I didn't realize, however that the bulb itself wasn't colored blue (only the light)...I was in the middle of starting a return when I looked at the box more closely and saw that it indeed said blue. I thought my order was messed up and I had been sent white bulbs. But after testing one and discovering that it was indeed blue light I was thrilled! --- ## 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.hk/products/320487177-ameriluckcolored-a19-led-light-bulb-deep-cobalt-blue-with-black](https://www.desertcart.hk/products/320487177-ameriluckcolored-a19-led-light-bulb-deep-cobalt-blue-with-black) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-30*
