Video Transcript for Gustafson Double Dome RV Pancake Light Installation

Speaker 1: Today we're going to be taking a look at the Gustafson RV Double Dome Pancake Light, Part Number 277-000340.This LED Pancake Light is a great upgrade, or replacement, for your RV, camper, or enclosed trailer. It features two clear lenses with a textured pattern. This is going to help disperse the light throughout your camper. It features two modes. We have a single light and a double light.With the lenses removed, you can see the 18 LED's. There's nine on each side.

The overall dimensions are four and three quarters of an inch long, 11 and a half inches wide, and one and one quarter of an inch deep. Customers on our side are using these to upgrade from the old incandescent lights to LED's. LED's are more efficient. They last longer. And there are no bulbs to replace.Now that we all know the features I'll go ahead and show you how to get it installed.

We'll be replacing our old light. Let's go ahead and start. We'll want to first make sure the electric is off, and then we can take off our lens covers. We'll pull back and then take them out. We'll want to remove our old hardware.

We'll also want to save those because our new one doesn't come with hardware.With our hardware removed, let's go ahead and pull it down and reveal our wiring. As you can see, the wiring uses wire nuts, so we're going to go ahead and reuse those. We'll just twist them off.Now we can grab our new Pancake Light. It's a good idea to have the lens covers removed before you connect the wiring because it can be a little bit difficult to take them off once it's wired up. The way you take them off is you grab the two sides and squeeze, just like that.Now we can bring in our wire nuts and reconnect our wiring.

Our black is going to be our ground, so we'll connect it to our white. We'll just line up the wires and twist on our wire nut. Then we'll repeat the same process with our power wire, which is our red.Before we install our light it's a good idea to check our power. I've gone ahead and turn it back on, now let's check our light. I'd say it works good.Now that will know everything's working, let's go ahead and button up our install. Push our wiring back up into our ceiling. Want to get it lined up. With our hardware in place, let's go ahead and replace our lens covers. You want to be sure to slide in the sides first and then squeeze it to pop it in place. Looks like we're all set.And that's going to complete our look at the Gustafson RV Double Dome Pancake Light, Part Number 277-000340.

Gustafson RV Pancake Light - Double Dome - Clear Optic Lens - 18 LEDs - 277-000340

Average Customer Rating:  4.7 out of 5 stars   (108 Customer Reviews)

I updated the lighting in my motorhome to LED. These products worked great. They were roughly the same size so no alteration was needed. The light is great. Brighter and more white. I find the dual lamp to be very good when you do not want to light up the RV.



- 277-000340
by:

I replaced all the 20 year old light fixtures in my 19 foot travel trailer over the past couple of years, all this design. They look great, put out plenty of light, and I've had no problem with any of them. I've completely upgraded my 2000 Fleetwood Mallard with purchases from etrailer

This Gustafson double dome clear lens light item #277-000340 works fine for where I am using it. It should be noted that a "slim" low profile light will sacrifice coverage area due to the lack of depth of the fixture. In other words, the radius of coverage most likely will not be as great as compared to a fixture with more depth because a lens that has more depth can provide a wider radius of coverage. This isn't a big deal for the location I am using this light but it might be for some people in some applications. Because there isn't a lot of options for dual LED lights that can be switched to only one side or both I decided to give this one a try. It also was one of a few that was large enough to cover the holes from the old fixture. I do like the apparent brightness gained over the old incandescent fixture and I am happy with the "whiter" light. I am also very happy with the far better efficiency of the LED source. I measured its current draw at approximately 1/6 that of the old fixture. The LED fixture draws approximately .25A per side versus the incandescent at 1.5A per side. LEDs also generate far less heat. I find no downside to LED fixtures, only great gains. If you try a decent LED fixture I doubt you will ever again be satisfied with an incandescent fixture. They really are that much better.

Very nice bright lights . Screw pattern fit exactly the one from the old lights. One thing to note in my motor home you must check the polarity of each light . One side is the reverse of the other. I am pleased with them .

Working fine

Great light.3 watts per side, 6 watts total. Now have our entire travel trailer switched over to these lights. Can now go whole weekend on one battery and still have some juice left afterward. Easy install.



- 277-000340
by:

The product was exactly as described on the etrailer website. A great replacement for the original lights in our Airstream camper.



- 277-000340
by:

Love these lights. we changed over to these lights in our older ( 2007 ) trailer 2 years ago, nice and bright, and they hardly use any power. great battery life, I don't even weary about how many lights are on in the trailer anymore. and the switch design is great, your able to turn on one side or both, whatever amount of light you need. Now we just bought a newer ( 2013 ) fifth wheel and immediately upgraded all the lights to LEDs. once you have had LEDs in a trailer you will hate going back to regular lights. Incandescent lights take to much energy and are a lot dimmer. also these LED light Fixtures, are a good looking light, easy to mount, the lens are easy to remove. And there not very tall, love the low profile.


Comments
They are still working great, no problem, love the energy savings, they just Dont run the battery down.

I ordered two interior lights for a toy hauler and received them in a couple of days.I’m very impressed with the business and would definitely recommend them. Five star service.



- 277-000340
by:

Awesome LED, energy saving light. Very bright. Love that I can turn on just one side if I want. This is now the 4th one I've purchased for my travel trailer. I'm in the process of slowly swapping out all the original equipment ones with these. Will be purchasing more and I highly recommend.



- 277-000340
by:

Love these lights! Very bright, efficient and the fact that you can select 1 or 2 lights on is great. I've just purchased and installed my 3rd one in my travel trailer. what a difference they make. Way brighter than the battery sucking incandescent lights that came with the camper. Will be buying more until I have all the original ones replaced.



- 277-000340
by:

Huge improvement in my 2004 RV! If you want "bright white" lighting, then these are for you! It took about 45 minutes to replace 9-fixtures in my RV. Very stylish design....highly recommend this upgrade.



- 277-000340
by:

As usual, the product arrived on time and in perfect condition. The polarity of the hook up wires were reversed. Once I figured this out, the installation was a breeze. I replaced 3 broken original equipment fixtures that had incandescent bulbs. Boy are these things bright! This was a pleasant surprise, much better lighting than the original fixtures. The mounting hole pattern matched the originals, that was also very nice. Overall, despite the polarity mix up, these LED fixtures are a great value and I would not hesitate to recommend them to another person.


Comments
Still very satisfied, will be replaceing the rest of the original lighting with these as they fail.

Very happy with the brightness. I really like the fact that I can turn one light off if I need to. One light on is still brighter than the normal energy sucking incandescent lights that came with my camper. I've bought 2 so far and plan on replacing the other 6 in my camper. Would recommend.



- 277-000340
by:

Great service and very quick delivery. Very way to deal with and very responsive to my questions. Excellent!



- 277-000340
by:

This led fixture provides more light and less heat, it looks elegant too. Installation was straightforward after watching the video on eTrailer.com. There were no instructions included with the product though, and the video did not mention the mounting holes for the new light are not the same as the old brand; thus you will be drilling new holes in your roof.

Light really works nicely, very bright and a breeze to install. Ordered another already. Nov 24, 2018

Bought this light fixture to replace the original incandescent bulb fixture. Installation was fast and easy. I absolutely love the bright white result.

Still working and bright

I bought several of these light fixtures to replace and upgrade our lights in our travel trailer. I am very happy with the price and quality of the product and my wife likes the brighter, whiter lite that it puts off compared to the original light fixture. She is having me to replace the remainder of the fixtures because she is so happy with these replacements.



- 277-000340
by:

These LED lights are great. The color temperature works nicely with the existing incandescent RV lighting. Very nice dealing with ETrailer!



- 277-000340

Easy install and perfect replacement. (however, wish there were a version available with accessory plug-in for reading light on an extension cord, which was on the replaced original light)

Lights continue to work flawlessly

Wanted LED replacements for my 05 Weekend Warrior. These covered the area of the existing fixtures, and put out more light than the incandescent, or LED replacement bulbs I tried. Color is excellent. Not yellow, green, or blue. Bright, white light. Will be replacing all my RV's fixtures with these.



- 277-000340
by:

Light is bright and good efficiency. Much better overall than a typical halogen or tungsten fixture for camping use. Light temperature is a little "cold" compared to incandescent but not overly harsh. After buying one fixture I ended up replacing all of them in my camper and added a couple more, increasing the overall available light inside while still saving power overall.



- 277-000340
by:

Worked great. I used the clear ones on the cealing and the frosted one's above the benches. Makes the trailer a little brighter but not to bright. Great energy savings. Lower profile gives you more clearance. The 4 center mount holes were the same as the ones that I removed.

I apologize for receiving a defective product. Customer Service will be sending out a new one.

We've had this light in our trailer for a year now and it's held up well. It gives a nice white light and is very bright compared to the original lights. Build quality seems better than the original light as well. Definitely recomended.

  • Kelvin Temperature for Gustafson RV Pancake Light # 277-000340
    The Gustafson RV Pancake Light # 277-000340 referenced in your question features a warm light with its 18 LEDs and a lumen output of 225. When I reached out to my contact at Gustafson for the Kevlin temperature they stated that they do not keep this information on their lights like this one. I have attached a short video demonstration on this unit as well so you can get a closer look at its light output and color.

    The Gustafson RV Pancake Light # 277-000340 that you referenced has LED bulbs which are going to last a long enough time that you'd never really have to worry about replacing them. They aren't replaceable but since they are LED panels you really wouldn't need to worry about it.

  • Recommendation For Compact Interior RV Lights
    The Gustafson RV Pancake Light, Item # 277-000340, has three settings: off, one light, both lights. Based on my research, dimming the lights is not an option. How many lights you need would depend on how much light you want in your van interior. I recommend going with 3-4 lights depending on your needs. Contact us if you have any other questions.

I recommend taking a look at the Gustafson RV Pancake Light - Double Dome - Clear Optic Lens - 18 LEDs # 277-000340, which is a bright LED pancake style light with a switch. This light is 11" long, so it's a bit longer than the light you're replacing, but that's just going...

  • Wiring Installation for the Gustafson RV Pancake Light # 277-000340
    You are correct that the red wire is for power and the black is for ground on the Gustafson RV Pancake Light # 277-000340. When it comes to connecting it to the wiring in your trailer unfortunately there are no standards when it comes to that wiring. Simply test each wire with a circuit tester like part # PTW2992 to see which one receives power and then connect the red wire to that.

  • Comparing Lumen Output of Two 18 Diode LED Lights
    The Gustafson RV Pancake Light - Double Dome - Clear Optic Lens - 18 LEDs # 277-000340 has a lumen output of 225. The Optronics LED RV Interior Light with Switch - 18 Diode - Surface Mount - White Housing # RVILL34 has a lumen output of 920 raw but 815 effective. The Optronics option in this case is a much brighter light and approximately equivalent to a 60 watt incandescent bulb. Unfortunately there is not a clear lens confirmed to fit this unit.

You do not mention what the dimensions are on your current Jupiter lights, I searched online and from what I was able to find think they may be a similar 4-1/4" to 4-1/2" light. The # 328-K-58L34P9 requires a 3-3/8" diameter hole for mounting with overall dimensions of 4-1/4". It is a 2-wire design and is dimmable with compatible switch installed.

    I believe what you're referring to is a Bargman double interior light fixture. Bargman manufactured this lamp back in the 90's, and it's been discontinued for quite awhile (as well as the lenses) so your best bet would be to replace the fixture with currently available, similar lamp like # 328-001-902XPW from Command Electronics. For a similar style LED lamp, I'd recommend the # 277-000340 from Gustafson. The LED version would be brighter and would draw just a fraction of the power of...
