Yes. 3000-3500K. And, the closest brightness to 20W would be 300 lumen.

LED vendors may label it soft white or warm white, without providing K temperature.

There can be a variation in color shade between LEDs from different vendors even if they are labeled the same, ex. 3500K or warm white. Or - between the identically labeled bulbs from the same vendor. China is China.

But the K temp you are looking for is 3000-3500K.

If you want a warm light, like the 1156 or household bulbs, you need to stay between 2700 and 3500 Kelvins. 4200 still has some warmth to it and by the time you get to 5000+ the color goes to stark white. From 4200 down to 2700K colors will look natural, food will look right and so will you.

Also be sure that they are not polarity sensitive and have the latest generation of components so they don't interfere with your electronic stuff. (some don't have filters). Operating voltage should be between 8 & 30 VDC. The 1156 is approx. 165-170 lumens.

4000K to 5000K is more of a pure white.
7000K is a harsh, blue-tint white that I don't like for interior use.

36 of 5050 LED's or 48 1210 LED should equal an 1156 bulb.

Now - do you want flat panels, or the "cob"-style bulbs?

I got my 36-1210 warm white panels from seller 2011_led on Ebay.

I am not sure about the flat panel, as to how it would stay in the semi-round ceiling fixtures.
What color temp is the 36-1210 warm white panels?

I go by "Warm" or "Cool" For some thing I like the "Warm" which tends towards yellowish, "Cool" is bright white or very very very slightly Blue.

Alas soem companies way "Cool White" but it's true blue and dim.

I got a bunch from E-bay a while back. Sadly do not have a link They are good matches for a 1141 (Bit dimmer than the 1156) though they were advertised as 1156 alikes.

Hold on Alas no markings on the package and return address on the shipping label is faded.

I have a mix of cool and warm white here. Cool in the kitchen for example, and both (Different light switches) in the bedroom.

Everyone has different ideas on color lumens etc, You are fortunate is that the prices are much cheaper now and you can afford to experiment a little before you dive in.
Myself, I quit using the panels because of the mounting hastle, and then the adneasive failing. Now I use nothing but the regular shaped bulbs that you just plug in like the 1156 w/ leds stuck on them

We got our 36 or 48 led panel lights from e-bay for 2 or 3 dollars about three or four years ago. They have worked fine.

I bought mine for the Class A I had at Cabinbright.com the were 30 LED 5500K, 415 Lumens for about $9 each and they have different ones call and ask Joe he his very good.
