20x Super Bright 921 194 T10 LED Bulb, Pure White 12V 24-SMD Wedge Lamp For Boat RV Trailer Camper Motorhome Ceiling Dome Interior Light (Pack of 20)

Review “20x Super Bright 921 194 T10 LED Bulb, Warm White 12V 24-SMD Wedge Lamp….” retrofitted into RV interior.I was concerned about reliability, apparent brightness, color rendition, the possible RF interference that has been mentioned in reviews here. Also, I have been searching for good pricing on a retrofit so cost/value is a concern. I will hit each subject below. All 20 modules were installed in interior dual-lamp and a few single-lamp fixtures on 1/22/2018, replacing most of the standard incandescent lamps in the interior of our 2006 Coachmen Mirada 330SL. Overall, I am pleased with these and will keep using them if they work long term.>Reliability: Initial reliability was 100% as all 20 of the modules worked when installed. I installed and left them on for somewhat over 1.5 hr. All were still working just fine and the fixture lenses were cool. Longer term reliability will be updated as we go on camping trips beginning spring 2018. (Also, I accidentally installed one backwards and it still worked fine, although it doesn’t make sense to only illuminate the reflector from a distance of ½ inch. These modules have on-board switching power supply or regulators so voltage polarity does not matter)>Apparent Brightness: I was pleasantly surprised that illumination of objects below seemed marginally brighter than the old incandescent. Pictures of the fixture with one incandescent and one LED module installed do appear not as bright though. I attribute this to the fact that the fixture reflector is not illuminated at all with the LED modules, but is illuminated with the incandescent bulbs.>Color Rendition: I got the Warm White (3000-3500K Color temperature). Mostly brown and grey colors in the interior were pleasing to the eye. I did not notice any odd appearance on other color items. I have no problem with the color rendition.>RF Interference: I purposefully monitored the two TV’s, XM radio, FM radio, Garmin GPS, and TireMinder TPMS, and my Apple Iphone while installing and turning on ALL the fixtures that had LED lamps installed. The TireMinder TPMS uses a dedicated RF link from a repeater in the back of the motorhome AND Bluetooth link to the Apple Iphone. (I did not try AM on the radio as it does not receive anything on that band anyway).When the front TV (a 32 inch Vizio flat screen) was on, and the fixture within 1 foot of the top front of the TV screen was on with LED modules installed, using the antenna and local TV stations, I lost signal on exactly one local channel (and its sub-channels) ONLY (that was 13.1, 13.2, 13.3, RF between 210-216 MHz). This did not occur until the fixture had been on for a few minutes. But, strangely, it was reproducible immediately after that first few minutes by simply turning that fixture on and off. With that one fixture off, but all others with LED modules on, there was no interference noted. The rear TV (a Samsung flat screen) had no interference on any local channel, including channel 13. The nearest fixture to the rear TV is about 2 feet from one corner of the flat screen.The XM radio worked fine throughout. The Garmin GPS, sitting on the dash maybe 4 feet below and 2 feet over from the nearest fixture always had satellite lock. The FM radio I scanned through several local stations and all sounded normal. The TireMinder TPMS registered apparently correct pressures and temperatures on my Iphone App (Bluetooth interface). My Iphone cell strength registered 3 of 4 bars throughout the length of the RV when held at eye level, walking through slowly and stopping when phone was near each powered fixture. The house wifi is at least 75 feet from the RV and looking through several walls and a metal garage door so I paid no attention to it (e.g. I did not set up a test for wifi interference).>Value: Well, I can’t complain about these for $1.14 each including free shipping!>Vendor/packaging: Vendor met the PRIME shipping time. Outer packaging was good (a padded bag with box in it - modules are in another bag in the box) but 20 modules are in a bag with no individual padding from each other. There were some tiny pieces of plastic or other debris in the bag but all worked so it was no problem for my shipment.>Insertion force: They did require a fair amount of force to insert in the socket as other reviews have reported. I held the socket with one hand and firmly forced the lamps in with the other hand as I was afraid I would break the socket mount. All went in and I would rather have them tight so they don’t vibrate out.>Other: The lamps in the shower fixture, vanity (decorative bulbs), and front dash fixture have different bulb base types so I will have to find a different retrofit for them. The orientation of the socket for the stove hood lamp is such that this module would be turned 90 degrees from what is needed so I did not put one there. I don’t plan to retrofit these in the basement compartment lights due to humidity exposure. I’ll keep looking for something sealed for them. I may play with RF shielding and grounding the LED modules/reflector in the fixtures near the front TV that that had interference to see if that helps.I forgot to have my wife plug/unplug RV from shore power to see if there is any brightenss change or other effects. Will do that soon and edit this if possible.If any of you engineers/tech types have access to a spectrum analyzer, a spectrum picture of RF noise output from one of these would be interesting.Photos: 1) Compare incandescent in left side, LED in right side, without lenses installed. (pix is rotated CCW 90 degrees) 2) same with lenses installed 3) TV interference 4) pix from floor level looking at front fixture (by TV) with 2 incandescents installed, and other fixture with 2 LEDs installed.

Bought these led bulbs to replace the incandescent bulbs that where originally in it. The popped right into the connectors easily. I only needed to use 14 but they all worked perfectly. The attached pictures shows how much whiter and brighter the light is.

We were very excited to receive our New LED bulbs. We were told energy efficient,longer lasting and would not run as hot. We installed 22 new led bulbs on Saturday in our RV. Today on Monday while one light fixture was on it caught fire and melted part of led bulb. The fixture still works but bulb is melted. Pictures attached scared me to say the least. Thank goodness we were in the RV steps away able to handle and put out and remove so no major damage done. The rest of the bulbs are fine so far in the bag we had one that would not work in any fixture so we figured it was a defected one and threw it away. Well I would say this next one was faulty also so we removed it. We cleaned up the light fixture waited awhile put another bulb in and so far fine. I like the bulbs nice and bright. I will continue not to leave these lights on while we are not in RV always afraid of something happening when not there. Still nervous about them will wait to see if any more defects from the bag we purchased.

These LEDs provide a very pleasant shade of white light, which is a more natural looking light. I changed out all the interior lights in my 5th wheel with these. The lighting is more the bright enough and looks good. There's no yellow glow from these lights. Out of a package of 20 bulbs, all 20 worked. I'm going to order more to replace the lights inside my exterior storage compartments.

Third time is the charm. This purchase represents my third attempt to upgrade the incandescent bulbs in my RV to LED. My first attempts were for inferior dim LED bulbs that did not cost very much. Neither of these were as bright as the factory installed incandescent bulbs. These new bulbs are great. Good combination of color and brightness.

Replaced all my RV lights with the LED pure white bulbs. Greatly increased my lighting while using minimal power. Bulbs stay cool even after extended use. The only negative is that they do cast a few streaks of yellow and white which are slightly noticeable on my countertop and bathtub. That is not enough to keep me from giving them a perfect 5. After seeing them in my RV, I had 2 other family members get me to order the LED bulbs for their RVs also. Highly recommend changing to these bulbs.

Purchased and install these in my RV over the weekend while camping. I have 20 bulbs and when you are trying to run your AC, Water Heater, or Microwave every amp saved is important. You know how it is being in a campground when it is holiday full and voltage starts sagging...we even lost power for a short time.. Anyway I put them and wow they are bright. They were a little whiter than I though they were going to be and much whiter than the 921s but I quickly got used to it. I realize now with the natural wood and brownish floor in the camper, it was really too yellow so these are perfect.They were so bright that in many of the fixtures, I turned them upside down so the light points up to the reflector and I get a little more indirect light. Over the sink and shower I used it pointed down since I want plenty of light there.My battery is a little tired and when the inverter would switch off, you could see a noticeable drop in brightness of the 921s. I had all 20 of these on and could not even see them blink when the inverter went off.The only thing left to test on these guys is longevity. Some of my bulbs were almost 10 years old....what will these bring?

I used these led lights in my RV trailer to replace older and poorer led lights. These are indeed super bright and the color temperature is perfect for a trailer. The other plus is that the leds are all on the side facing out so light isn't wasted. All lights worked as promised with no failures so far. Hopefully they will be the last ones I have to buy for this trailer.

I put all 20 lights in my RV, they all worked and are super bright. They had me giggling like a little school girl and telling everyone one I know with an RV about them. They create very little to no heat, telling me they are not wasting energy. It's been a couple of months of using them in freezing temperatures and they still work as good as the day I put them in. If GRB (the seller) needs a spokesman for this product, I'm their man!

I just got this RV. It's been about a week running bulbs all day while I worked inside. No issues at all. The are certainly brighter than the standard bulbs. Much better. Pushed in the socket with NO issues, tight fit. Hard to see in the picture but they work better. I was straining my eyes before with the standard bulbs.

I was worried when I bought these lights as my other half really dislikes white light. However after installing this was really a soft light and if I were to guess it softer than what its rated at which is fantastic when you want to relax in a camper.This was easy to install, shape shined the light in the direction needed and fit in the standard plastic housing. FYI-I installed this in a 2007 Rockwood rv. FYI- I did not rate the longevity because I haven’t used them for long.

As it turns out I was dumb enough to order these without checking my travel trailer to see which design of bulb I needed. Finally found a place for 1 in my trailer, and easy install/great light output. I have given the balance to a friend who is very happy with the performance also.
