GRV G4 24-2835 SMD Interior LED Light Bulbs for RV,AC/DC12V-24V Super Bright 2W Replacement of 20W Incandescent Lamp,Warm White Lighting for RV Camper,Cabinet Dome Light,Boat Light, Pack of 10

If you have round puck housing for the G4 light bulbs, these flat circular one-sided LED lights are much brighter than the T4 JCD type. The 24 each 2835 SMD LEDs are very uniform and stable. Now I can see what I am cooking. :-)

Replaced all the interior lights in my toy hauler with these. They provide a nice clean light.

We have a 2010 Tiffin Phaeton MH which originally came with halogen bulbs in the ceiling lights. We replaced those in short order (in the first year of ownership) with LEDs purchased from the supply which Tiffin was using at that time (at a cost of $7/light for 58 LEDs).As time went by at least half of the new LEDs had partially stopped working or, worse yet, began a bit of flickering.We finally decided to replace all 58 LEDs with new ones. It's always kind of risky purchasing "sight unseen" lights here on Amazon (as I've done a couple of times). I decided to give these a shot. I selected the "Cool White" bulbs in packs of 20. Price came out to $1.79 per bulb.I was a bit apprehensive after reading another review in which the owner had to remove the black plastic insulator and cut the legs a bit.I have included a picture of the true measurements for this LED as the description concerning overall length is wrong. The description is 45mm in total length, but mine were actually 39mm. The height of the electronics on the back of the board bothered me also, but the total thickness is 7.85mm and posed no problems. I appear to have the same ceiling sockets as the other poster, but I did NOT have to remove the insulators nor clip any of the legs.I just installed these, so I cannot address longevity, but I love the color (which I would describe as "Bright White".

I have IKEA puck lights in my kitchen as undercabinet and top of cabinet uplighting. The 10W halogens are a pain to deal with, require fiddly installation to avoid contaminating the bulbs with oil, are constantly burning out here and there, and throw a decent amount of unwanted heat.After finding these COB style wafers I decided to bite the bullet and do a swap. I didn't want to use LEDs that try to be bulb shaped because LEDs shouldn't be used in reflector housings as the light pattern usually looks like garbage.Upon initial installation they were great, the light quality is good, it's not great, but good enough for my purposes. However, I have simple AC/AC transformers taking 120V down to 12V because the original IKEA power supplies have all killed themselves with heat. Those did put out DC current.These lights do flicker on 12V DC if they are the only load on the circuit. It's fairly annoying and I was seeing it all the time. I got 12V DC drivers to swap my transformers with but haven't taken the effort yet to do that. In the meantime, if each circuit has 1 halogen bulb in it, essentially a resistive load that smooths out the AC, the lights flicker a little, but it's well within my tolerance.I'm somewhat disappointed because they do have a nice sized electrolytic cap on the board, but it must not be enough to smooth out the AC.

I tried a few different bulbs for my under-cabinet puck lights. Either they didn't fit, got too hot, weren't bright enough or all three. These bulbs finally did the trick. They apparently have a very good voltage regulator circuit on the board and they are plenty bright and seem to be lasting. Like other reviewers have noted, you may have to trim the pins off if they are too long, and maybe even removed the small plastic spacer at the base of the pins to make them fit in your fixtures the way they should but definitely worth any small modifications as they are good quality.

Low profile, pins are a little long and may need trimming if installing in a standard 3 inch RV puck but a great improvement over the halogen bulbs.

No way these are 7000k. I'd say closer to 4000. Too yellow for my taste, but will keep them as spares, as they seem to work ok.

Bought these to replace 12V halogen bulbs in a range hood. These run cooler, put out more light, and cost less than original bulbs and theoretically last much longer.Little bit tricky to install since they are slightly larger... but they still fit after getting them in at the right angle.

I used these in my RV, it’s a perfect match as far a color to what I had. With the stated color temperature of these lights, I was concerned that they might be on the purple side but they are a very bright white light. The only issue is the pin spacing is not correct. It’s not difficult to bend them with needle nose pliers to get them to fit.

Very good

These bulbs have replaced halogen lamps and are just as bright. Also saving lots of battery power on my RV

クルーザーの室内灯で使用していますが、純正品よりも、はるかに低価格には驚きです。

Replacing all the Incandescent lights in my RV over to LED. These were easy to install and are much much brighter. The price is right compared to purchasing these lights at an RV dealership parts store. Love them
