Bulb to LED light conversion

I have 11 double fixtures that contain 921 bulbs with the wedge base.
I would like to convert over to an LED type replacement light, but would like to drop the brightness down. I have clear lens and for the 921 bulbs I have read it puts out 265 lumen. Has anyone done a conversion from the 921 bulb? If so, what did you go with and did you go with an equivalent brightness or less? thanks, Tom

You want less light.. I want more.. Good thing they make a range of lamps that fit those sockets ๐Ÿ™‚ by the way a common dash indicator lamp Very small) will fit in that same socket.. I know, that's how I test them to be 1000% (yes I know too many zeros, not) sure that the problem is the lamp bulb, not the socket,

Super Bright LED's is where I would start, I like Cool White myself for the color chart but pay attention to both the color temp and the lumens.

I tried looking up the lamps I use but alas the corporate web page loaded very slow and did not list them. They are 1141 replacements. Light is between a 1141 and a 1156. draw around 2 watts.

And the catalog did not list color temp.
Home was where I park it. but alas the.

Thanks all for the information. I did just purchase 4 paddle looking type that fit the wedge base like the 921 bulbs. When with Ebay due to price and they are from China but had a local warehouse so they shipped quick. Here's the link http://www.ebay.com/itm/131124918044?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

That is a colon M after STRK (not the angry emoticon) LOL

I'll take a before and after of the fixture lit.

If you replace your bulbs with multi LED bulbs, all it takes is a small paint brush and some black paint to adjust the brightness to whatever you feel comfortable with. One of those little jars of model paint, in black, worked fine for me. Just dab it on to block the light from as many LED's as you need. In the future, if you want the light back, just scrape off the paint.


Excellent idea!!

x 2. That's what caused me to switch to a much brighter LED bulb.

I have purchased two sets of these so far and have had no problems. I'll probably get more soon. They work great.

Easy to install, bright and good color. I've also used them with a limit switch and a 9-volt battery for a great light for small spaces such as a cabinets, safes, etc.

Has someone on this site made a comprehensive list of part numbers and the equivalent LED replacements?

I'm assuming this is what you want to do, but not for $50 on Ebay.

I would not buy all 20 bulbs all at once. Buy a couple of each type... bulb and panel with different amounts of LEDs/brightness in warm white, not bright white. Most of us on here have found that the panels give off better usable light. There are plenty of posts on here on this subject.

Ivylog, you mention using a panel versus the wedge based "bulb" shape. Please tell me why and how you determine which would work better. since I have over 20 "bulbs" to replace it really is important I get the right one. All my lights are the pancake style lights that fit flat against the cabinets or ceiling.

Do not confuse me with facts, my mind is made up.

I looked at the m4 site and did not see where they were made in the USA... some are assembled in the USA with leds from China. The only US manufacturer I've been able to find is CREE in NC but only in 120V.
I would suggest a LED panel in warm white for $0.36 each delivered or $12 from M4:S. A 921 is the same as a T10 wedge base.
PS, I've bough over 60 different LEDs from China on Ebay over the last four years and to date I've had one fail.

Thanks Dave and Jerry for your input and links. The 921 incandescent bulbs make me feel like I'm in surgery. I think they're way to bright and so does my wife.
Do you know Jerry which 921 replacement LEDs you went with? I may have to buy 1 set at a time to see.
The photo with the LEDs on that comparison I gave you has the 921 LED bulb catalog number. I bought them from superbrightleds.com.
