LED interior lights follow up

Finally got my t10 base interior LED lights.
I bought a 10 pack for right at $10 including shipping from China.
NOTE- LEDs are polarity specific. If you plug in an LED and it does
not light, turn it around 180 deg and try it again.
When using in outside as landscape lights (on a 12v AC transformer)
polarity doesn't matter.)

They arrived today. I put 2 in a couple of my interior ceiling fixtures.
I also used 3 in outside tier landscape lights.
My landscape light bulbs typically last less than a year and cost about a
buck each at Home Debit.
These will work there also.

Time will tell about lifespan on the LEDs but they "should" last many
years.

Pulled out the fuse for the ceiling lights and stuck meter set on amps scale
in the place of the fuse to check amps.

2 normal incandescent bulbs in a ceiling fixture get HOT immediately
when turned on.
They draw 2.7 amps
2 LED in the same fixture draw .17 amps
That means normal bulbs draw 15 times MORE current than these LEDs.

The LEDs are cool white- slightly blue tint.
They are not as bright as the incandescent but plenty bright for moving
around, getting dressed, making the bed etc.....
I am not going to change them all but I am changing some.
When we are on battery power I'll use the fixtures with LEDs.
On shore power I won't care except the LEDs run cool and the incandescent
will burn your fingers after just a few seconds illumination.

As an aside, we also have a "thinlite" fluorescent fixture over our kitchen
table. It draws 1.5 amps. Slightly more than half the incandescent but
it puts out as much or more light. We use it for writing post cards, reading
the paper etc....

Here is the link for the LEDs I used--
10X T10 W5W 20 SMD LED 1206 Car Side Wedge Light Bulb 194 927 161 168 White Car Door Light Tail Lamp Backup Lighting-in Light Source from Automobiles & Motorcycles on Aliexpress.com

Note they are now $9 for 10 "bulbs" incl mail from China.
Can take 3 to 7 weeks for shipping depending on how long customs
takes to scan and pass them.
Aliexpress do not share your credit card number and they don't pay the
seller until you receive your merchandise.
So far I have had no issues with buying this way.
YMMV.

What lumen are these bulbs?

Sounds like a good deal.

For $8.99 this is hard to beat. I can replace the rest of my interior lights for the price of one LED bulb that I have already used. Even if the color (a little blue) doesn't match I am sold. Now what do I do with 20 old HOT bulbs?

From the research that I have done, those bulbs are 100 lumens for some, the best I have found are 180. The WARM white casts a more natural light color, sort of a yellow tint. I bought 20 bulbs that were cool white from a Chinese supplier on e bay (hong kong) for 22.95, free shipping. They are 180 lumens, and are bright enough, but have a bluish white tint to them.
921 T 10 W5W 24 1210 SMD LED cool white lamp. Next I got 10 of the 12 SMD 50 50 LED WARM white landscaping bulb- right color, not bright enough.
I am still searching on e bay for the right ones! All of the merchants on e bay must use Pay Pal. Very safe to use. Randy

The one's I got are NOT as bright as the incandescent bulbs.
I'm gonna guess half maybe.....
I'm not changing all mine. I'll leave some ceiling lights with bright and hot
incandescent and change some so when we're on battery power I can
have decent light for just a tiny fraction of the power used by incandescent.

Remember if you plug one in and it doesn't light, turn it 180 and try again.
The super low amps on the LEDs means I could change them all and
turn on EVERY light in my trailer and it would not draw as much
current as a single ceiling fixture with 2 incandescent bulbs.

If you are keen on boondocking you need some of these or something
similar.

I'm sold on the idea of the LED bulbs. However, I'm disappointed in the "el-cheapo" bulbs from China . I ordered a package of 10 a few weeks ago, and replaced Halogen bulbs throughout the camper. So far, I've had to throw away one because it started blinking (bright/dim/bright/dim); another went out entirely - when I pulled that bulb one of the segments apparently had a cold solder joint which had separated . I've ordered replacements, and spent a little more on bulbs through Amazon, so I hope they'll be better quality. I'm planning on going solar, and the difference in current draw will make the solar more effective. My little class C doesn't have room for more than two batteries, so current draw is going to be critical.

Just replaced 20 wedge base 921 bulbls with 250 lumen Natural Light tower style bubls for less than $9.00 each, no shipping charg. Ordered on a Friday and received on the following Monday. All worked and really enjoying the LED bulbs. Bought at RV LED Bulbs (Ocala Hitch). Great service and nice people.

The thing that concerned me more than the power usage of the standard bulbs, was the extremely excessive HEAT that they produce- on my light fixtures that I use the most, the plastic lens covers are actually melted from those HOT bulbs. With enough time ON, I worry about a fire, mine get so hot. That is my main reason for replacing them to LED. Randy

some are poarity specific and some arn't. At Superbrightled's they tell you right in the spec.

Hey guys, how do you remove the covers of the interior flat lights in the pop-outs. I have a couple burned out. I thought they would just twist and pop off but it looked like the entire light fixture was trying to turn. Do I use a flat-tip and pry the cover off? Before I damage it, I just wanted to check the best way to remove the cover so I can replace the bulb. Thanks
