According to http://www.jwspeaker.com/bulbs/ these incandescent bulbs have these specs:

• 1141 Current:1.440 Watts:18.00 Candlepower:21 Lumens:264 (I have four of these inside)
• 1156 Current:2.100 Watts:27.00 Candlepower:32 Lumens:402
• 1003 Current:0.938 Watts:12.00 Candlepower:15 Lumens:189 (I have one of these outside)

When I search Amazon for: "led 1156 natural" w/o quotes, I mostly see Gold Stars and HQRP.

 

When I search Amazon for: "Gold Stars led 1156 natural" w/o quotes, I find three results I like:

 

1) "6 sets of Gold Stars 11568301-06 LED Replacement Bulb 1003 / 1141 / 1156 Base 120 LUMS 12V or 24V Natural White"

http://www.amazon.co...l/dp/B00BSGBARW $39.95 ($6.66/bulb, Free Shipping, I have Prime)

 

2) "6 x Gold Stars 11568302-06 LED Replacement Bulb 1141 /1003 / 1156 Base 190 LUMS 12V or 24V Natural White"

http://www.amazon.co...l/dp/B00BSGLBQW $39.95 ($6.66/bulb, Free Shipping, I have Prime)

 

3) "6 x Gold Stars 11560040-06 Replacement LED Bulb 1156/1141 Base Tower 280 Lums 12v or 24v Natural White"

http://www.amazon.co...l/dp/B00BSG1P8Q $49.96 + $3.98 shipping ($8.99/bulb)

 

When I search Amazon for: "HQRP led 1156 natural" w/o quotes, I find two results I like:

 

1) "HQRP 4-Pack BA15s Bayonet Base 30 LEDs SMD 3528 LED Bulb Natural White for #93 #1141 #1156 RV Interior Ceiling Porch Lights Replacement + UV Meter"
http://www.amazon.co...t/dp/B00BWADJD2 $22.51 + $7.44 shipping ($4.99/bulb)
190 lumens.

 

2) "HQRP 4-Pack BA15s Bayonet Base 18 LEDs SMD 5050 LED Bulb Natural White for #93 #1141 #1156 RV Interior Ceiling Porch Lights Replacement + UV Meter"
http://www.amazon.co...t/dp/B00BWAEP9O $24.51 + $7.44 shipping ($5.33)
??? lumens.

 

MY QUESTION: Is there really that much difference between the 1141 (264 lumens) and the LED (190 lumes) or the LED (280 lumens)?  The LED (190 lumens) would be much dimmer... right?

It's not always about the numbers with LEDs. We were recently doing a similar comparo for home LEDs for my sons new place. Often the difference in lumens is related to the color. The bluer ones will be brighter or have a higher lumen number usually. Identical fixtures had different lumen numbers depending on the color range. The ones near 7,000* were higher in lumens. The ones at 4,500 were lower in lumens but much more natural in color. That's what we bought and they were fine.

 

Your eyes don't like blue light. They can't focus on blue well. Ever used a cheap LED flashlight? They seem real bright but you just can't see that well by them. Too blue! LEDs tend to be too hot in color temperature. Near 7,500* or very blue. The eye wants to see light that is between 3,500* and 5,000*. This is the whiter or more incandecent colors. Like sunlight. Hope this helps a little even if it isn't a direct answer to your question.

I believe you're confusing lumens with kelvin (color temperature).

I believe you're confusing lumens with kelvin (color temperature).

I agree with your line of thought, but I think what Squatch was trying to communicate is that lumens aren't everything when it comes to the ability to see things.  Sometimes a warmer color temperature is more important for visibility than more lumens with a cooler color temperature.  Meaning lumens aren't everything.

Thanks everyone for the replies and I did learn more about blue light.

 

I already was going to replace my 1141 bulbs with natural white LEDs.

 

Sorry I was not very clear what I was asking.

 

Is a 190 lumen LED the about same brightness as the 264 lumen 1141?

OR
Is a 280 lumen LED about the same brightness as the 264 lumen 1141?

 

I should buy the 280 lumen LEDs... right?

FYI...

 

According to www.eaglelight.com/category/lighting_tutorials.color_temperature/

 

To simplify the selection of LED light bulb color temperatures EagleLight uses the following definitions for various color temperatures:

• Warm White: typically from 2600 Kelvin to 3500 Kelvin
• Natural White: typically from 4000 Kelvin to 4500 Kelvin
• Daylight White: typically from 5000 Kelvin to 5500 Kelvin
• Commercial or Cool White: typically above 6000 Kelvin

 

Color temperature is an aesthetic choice, so each person will have their own preference for each setting and application. Preference is as individual and varied as there are applications and people. Here is what we have found to be generally true, but in no true for all people.

•Warmer Whites are preferred for dining and living areas and reception areas where you want a more relaxed environment.
•Natural Whites are preferred for kitchens and bathrooms where tasks are performed.
•Daylight Whites are best in retail outlets and offices, though natural whites are used in these environments as well.
•Cool Whites are used for industrial areas and hospitals.

 

Older eyes often times see better in cooler color temperatures. Women often prefer warmer colors than men. Task lighting is better if cooler. Cooler whites raise attention. Warmer whites soften the environment and make for a more relaxed space. Warmer whites will hide the true color of objects and add yellow tint.

An imperfect analogy but you could consider color temperature is how the beer (or wine, or coffee) tastes and the lumens represent whether you have a cup, pint, quart, or gallon of it.

This is what I meant. Not confused by lumens vs kelvin. When we were doing the comparison for my kids lights we also found that there seems to be a corelation between lumens and color in LEDs. Typically the bluer the light the higher the lumens from otherwise indentical lamps. Higher lumens means brighter. But is that always better? I'll be doing a similar coversion in my camper soon. A little dimmer lamps won't be a problem. In the few days I've had my camper I've found that of the 4 lamps in the camper just turning on 1 is usually plenty of light in the Eagle. So I don't think a somewhat dimmer bulb will be a problem. Just turn on more lamps if need be. 

 

The 280s should be brighter than the 264 incandecent.

My own experience: the bluer (higher Kelvin number) the light, the more "hollow" it feels. The light looks to be there, but it's not really useable. If that makes any sense at all.

[pvstoy]

5,000 to 5,500 (5200) kelvin is perfect viewing for prints and artwork. The higher the kelvin number the cooler to blue warm to yellow it becomes. Lower kelvin number the warmer cooler the light is to a yellow blue shade.

You can have different lumens at each kelvin number to make the light brighter or dimer.

Interesting that with the leds you see color differences with different lumens output strength. From what I hear there is a wide variance between manufactures.

Ones eyes will adjust and the brain will not see what the color of the light is. Take a book with white paper and read it under a florescent and then under a incandescent light. Your brain will tell you the paper is white. Take a picture and the image will show what kelvin temperature it is.

Edit for getting it right…
