Video Transcript for Gustafson Lighting RV Lighting - Ceiling Light - 277-000340 Review

Today we're going to be taking a look at the double dome light for RVs, campers, and enclosed trailers. This is a white colored pancake light. It's a 12 volt, six watt, light. The clear lenses allow plenty of light to come through. Those can easily be removed. They simply just snap off and on.

The unit's going to feature a rectangular, white, plastic, base. It's going to offer a very clean, finished, look to the unit. Nice rounded corners gives it a really sleek design. Right here in the center, it's going to have the easily accessible on and off switch. Here at the base, that's going allow you to control the functions of the light.

Towards the end of the video, we're going to hook it up to power so you can actually see what it looks like. I do want to mention that the switch has three different positions. You're going to have off. YOu're going to have one side on, and then you're going to have both sides on. The unit's going to contain 18 LED bulbs, nine per side. LEDs are going to be great replacements for incandescent lights.

They last longer, they burn brighter, they're much more efficient. You don't have to worry about replacing bulbs, and you don't have to worry about brittle filaments. The unit's going to feature eight mounting holes. To gain access to those, you just got to remove the lenses. Again, they simply just snap on and off. That's going to expose the nine locations.

That's overall, really nice design. It's going to be a two wire design. I do want to mention that the installation is a surface mount installation. You're going to have four mount holes per side, so eight total. Mounting hardware is not included. Two wire design is going to provide your power wire which is red, and your ground wire which is black. We're going to take a look at the overall dimensions real quick. Going this direction edge to edge, we're looking at five inches. Going this direction edge to edge, that's going to give us a measurement of right around 11 1/2 inches. Then the depth or the thickness, it's only going to be about one inch deep. It's a nice low profile light. The mount holes on the unit are separated on center going this direction by about 3 1/2 inches. Going this direction, we're looking at about 3 7/16 of an inch. Diagonal measurement, we're looking at about 4 7/8. Those are going to be the same for each side. Distance between these two holes on center, about 2 1/2 inches. Outer hole to outer hole on center, we're looking at about 9 3/8 of an inch. We're going to go and hook it up to power. That way you can see what it looks like with some power running to it. We'll also be able to turn off our overhead lights so you can see it in a low light setting. This light sends out a really nice strong consistent signal. Plenty of light output, a nice bright light. The clear lens allows plenty of of the light to come through. Again, it's going to contain nine LEDs per side with a total of 18. Right now it's in the fully on position. If we go down to the middle notch, it's going to switch the one function to just one side. If we go down again, it's going to completely turn the unit off. Nice quick response time with the unit. The multi-dowel design is really going to help optimize the overall light output of the unit. That's going to do it for today's look at the double dome light for RVs, campers, and enclosed trailers.

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

Average Customer Rating:  4.7 out of 5 stars   (55 Customer Reviews)

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. 423510

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. 424011

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. 568204

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. 316807

Awesome looking light when it's off and when it's on! Attractive ^^^ and perfect fit as it is a little big bigger in dimensions than old one so it covers up any old install marks and/or screw holes. It's very bright and great one light on capability for a dimmer light when needed . 416728

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. 595410

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. 434826

the led lights flicker a bit when you first turn them on but after a minute they work just fine. it could be due to the cold where I am, January in Colorado. 472641

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. 467009

When I got my 5th wheel trailer it was missing a light. Quality of this light is very nice. It puts out a nice white light. Not the bluish light with some LED's. It would be nice if it came with mounting screws though. No big deal! Great Light! 540233

by:

I really like this light! It's look when it's on AND when it's off is a nice look! And it's bright, so much so :) that the feature for turning one side off is very useful. It feels solid (quality) and was easy to install with a red wire which made for easy find for the pos/neg connection thx! 415586

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 . 471371

These LED lights replaced standard incandescent units in our camper. They were easy to install, use much less power, can switch one 1 or both sides ON as needed, provide a soft lower glare light, and should outlast the camper itself. Both my wife and I agree that they are a great improvement. 666628

- 277-000340
by:

It looks good and is very bright. The product info says it is 225 lumens, but I guess that is each side. It is comparable in brightness to the Optronics that is rated for 800 lumens. The light color is not blue/white like some LEDs and seems quite pleasant although the specs do not show the Kelvin rating. 642391

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. 599126

With this Class 'C' motorhome being 39 years old, I am gradually replacing the incandescent interior lights with LED-based ones. It's my opinion, that Gustafson makes quality lighting fixtures so that is the reason why I am using this particular Gustafson model LED interior light fixture. 598977



- 277-000340
by:

I have purchased a few of these lights at a time over the past year upgrading every light in my trailer, they are a great light and very bright. The square design was the main reason for purchasing since it covers the existing holes in my old lights. 597314

I was looking for as direct a replacement as I could get for a Bargman 253X twin 1003 bulbs light fixture for this 39 year old Higgins-Delta Class C motorhome that I have owned since new. I found your WEB site and chose the fixture you show above here on this page. Your LED fixture is almost an exact replacement for the Bargman 253X. The mounting holes line up and it was a snap to replace. IF I need to replace other light fixtures in this 'antique', I'll be back. I haver other Gustafson light fixtures in this RV - in the bathroom - so I am familiar with their quality. 588816

  • 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.

  • Interior 12V Dome Lights with Switch to Replace Bargman 89-Series
  • The Bargman 89-Series Interior RV light 30-89-007 is a 12V square incandescent ceiling light with a switch and that measures approximately 6 1/ 4 x 5 1/2 x 1 3/4-inches. We do not have this particular light but we do offer a wide range of RV interior lights and some are close to this light's dimensions. Others that are larger give you the opportunity to upgrade your interior lighting. For example we offer the Gustafson RV Pancake Light # 277-000340 which has high-efficiency LEDs instead...

  • 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.

  • 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.

  • 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.

  • Do Bulbs of Gustafson RV Pancake Light # 277-000340 Ever Need to Be Replaced
  • 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.
