The bulbs showed no interference if they are not located near the antenna cabling. **Q: got 5th the base looks like the picture base has 1 wire ea side left pic/right have 2 ea side. Are these bulbs wired for series or parallel circuits?** A: HI Don, These bulbs will work plugged in either way, it doesn't matter, at least in my application. I'm using them in landscape lighting, and they're great!! I got the warm white. The higher kelvin rating tends to wash out the colors of what ever it's illuminating. Warm white or 2700 to 3000 kelvin enhances colors. The lower the number the warmer. If what you are illuminating is all white then get 5000 to 6000 kelvin. **Q: Who makes these bulbs?** A: I don't know who made these bulbs. There no markings indicating place of manufacture. You might try asking the seller where they're made. **Q: Will this bulb fit in a 912 wedge bulb base?** A: Hi, Yes these will fit perfectly fine in both 921 and 912 wedge type base. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Truly amazing warm white LEDs *by J***. on Reviewed in the United States on July 11, 2018* I rarely write a review the same day I receive an item but I feel inclined to do so for these bulbs. They are amazing!I can't speak to the longevity obviously since I've only had these bulbs a day but as far as equivalency to the stock incandescent bulbs, these bulbs are an amazing match and only use a fraction of the power (4w vs 18w) which is really going to come in handy during our fall camping trip to Denali where there are strictly enforced generator run times which means we'll need our battery bank to hold up for the night.I purchased the "warm white" version because we don't like the "blueness" of high kelvin LED bulbs we've tried in the past. Like so many others out there, I made the mistake of wasting money on the low cost LED wedge bulb replacements widely available on the web only to be totally disappointed by the blue tint and halo effect of the light they put out, not to mention the color temperature being way off what the bulbs were advertised to be. Basically I ended up with a 10 pack of useless LED bulbs that ended up in the garbage and the old incandescent bulbs going back in. Lesson learned...When I installed these today I started off by installing a new bulb in one socket of a dual bulb fixture while leaving the incandescent bulb in the other socket. I did this so I could compare the light output and tone of the LED against the incandescent side-by-side. The results were truly amazing. I could hardly tell the difference between the two bulbs. Both were equally as bright and the "warm white" color tone was nearly equal between the two. I have to admit the LED was just a touch brighter and maybe a few kelvin higher on the color temperature scale but nothing like I've seen with cheap LED replacements in the past. Truly about as equal as I've seen with any LED replacement I've ever attempted.So I recommend you do yourself a favor, if you're serious about replacing your old incandescent bulbs with LEDs, skip the cheapos and go straight for these premium bulbs. In the end you'll save yourself a lot of disappoint. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars So happy with this purchase!!!!!! *by P***E on Reviewed in the United States on July 21, 2020* Shipping was instant. Ordered the 19th and received them 830am on the 21st. I ordered mostly bright white but also ordered warm white for above the couch and above the recliner. The photo shows the led above the recliner in warm white and bright white installed above kitchen sink so you can clearly see the difference in color of the led bulbs. I didn’t care for warm white so happy I ordered extra bright because I ended up replacing the warm white for bright white throughout entire motor home. The install was easy and quick. If I had known how easy it was I would have upgraded to LED sooner. The lights in the walkway with tallest ceiling height really brighten up the main areas. I am totally pleased with the product and the seller. I choose this seller because the reviews recommended this specific brand of LED bulbs so I knew I wanted their brand and the seller turned out to be awesome in both shipping and communication. Updates during the whole day, lol it took to revive them. I actually got a few emails with my order progress all way until delivery. I bought LED bulbs at an RV show a few months ago without bothering to check what bulbs I needed and still have them and having these to compare to. I can say these are much better quality bulbs and so much less expensive. I fitted my entire 30 foot class c for under 100 dollars where as when I got the wrong bulbs I paid the same amount for eight bulbs. I am happy with the clean crisp light they produce and I left the bathroom light one purposely to see if they got hot and they were cold to touch after a half hour so that is reason enough to make the switch. Also the phots shows the warm white cast a yellowish tone over my blinds and wall paper. The bright white depict accurate color of balance and blind ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great lights that are just right! *by A***R on Reviewed in the United States on June 9, 2019* I was concerned about installing LED lights in our trailer. It seemed that you only had the bluish, white LEDs that glare and are hard to look anywhere near them, or ones that were yellow and didn't have good light output. So with this aprehension in mind we purchased 8 bulbs to change the main house lights, and the lights over the medicine cabinet/sink and headed out on our trip. These 4000K lights are just right, they put out great light without the harsh glare. They changed a poorly lit main area into a well lit space that was pleasant to spend time in.The best part about these lights is the impact they have on battery usage. When running on shore power it was nice to not hear the inverter turn on with the lights. When we ran a two bulb incandescent fixture the inverter immediately turned on. I could run all 4 bulbs in the house lights all evening without any impact on the battery or noise from the inverter.Installation was a breeze, I was able to just swap out all bulbs in each fixture. The bulbs are a bit tighter fit, but a little wiggling of the bulb and it slide into the socket.These bulbs performed so well that our first purchase when we got back from our trip was another 8 bulbs to finish changing rest of the bulbs in the trailer. --- ## 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.kg/products/46762675-t10-4-0w-nw](https://www.desertcart.kg/products/46762675-t10-4-0w-nw) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-04-23*
