LED dome light comparison

I was finally able to get a comparison shot of the different LED dome lights I've tried.



The LED array on the left is one from autolumination (el cheapo LEDs that WILL burn out - I don't recommend them - try V-LEDs or Oznium if you really want to go this route).

The one in the middle is an old version of the TaskLED dome module. The one on the right is the CURRENT TaskLED dome module.

Last night, I did some testing in a 100% dark room using my power supply to juice up these three LED modules to 13v. The Lumen output of the two TaskLED modules is known (and fixed since they're electronically regulated), so I figured I could make a reasonable engineering guesstimate using a light meter (used in photography) to figure out what the output of the LED array was. Keep in mind that 13v is about the power in the vehicle with the engine running, and it is closer to 12v when the engine is shut off. I had previously believed that the LED array was dimmer than the older TaskLED dome based on what my eyeballs told me with them mounted in the vehicle, but my testing actually proved otherwise. :xnuts: :headslap: I think the cooler color temperature of the LED array (much cooler actually), and the fact that the array is dimmer when the engine isn't running may have fooled me. (so I suppose I wasn't totally wrong)


If I was forced to put a number on it based on my little informal test results, I would say the LED array on the left puts out about 50 Lumens, or 25% more than the older TaskLED module at the voltage levels in the vehicle with the engine running (the human eye needs a 20% difference in brightness to perceive a difference, and there is just *barely* a noticable difference). The TaskLED modules are spec'd at 40 Lumens for the old one, and 100 Lumens for the new one (currently - once he runs out of his current batch of 100 Lumen Luxeon Rebel LEDs, they'll be 70 Lumens like the website shows). The thing to keep in mind though is that the LED array was drawing TWICE the power of the two TaskLED modules (a little over 3 Watts vs. 1.5 Watts). If you could crank up the new Luxeon Rebel module to that power level, it would be putting out nearly 180 Lumens!!! (but would also need heatsinking)

It is hard to believe that the teeny tiny Luxeon Rebel 100 on the far right puts out TWICE the light of the array on the Left, but it does (without even pushing it hard). :bugeye:

Anyway, the main thing I wanted to show here is the SIZE difference between these three modules; the current TaskLED dome module is tiny!!! I was barely able to squeeze the old TaskLED dome module into the rear cargo lamp in my '99, but the new one fits with PLENTY of room to spare. This means the TaskLED modules will now fit places they didn't before as they're barely bigger than the festoon bulb they replace. The new TaskLED dome modules rock! HTH.

That's impressive. How do you install it?

Thumbs up Great Post

I am in the market for new, brighter dome lights in front and back. Thank you for taking the time to share your experience with these products

While I can't provide nearly as in-depth an analysis as CO_FlyFisher I will take this time to offer up my experience with LED dome lights in hopes I can help someone make their decision.

I ordered the Oznium Ultra-Thin LED Dome Light in blue, size 2.0"x2.0" and I have been very happy with the purchase. While it is a little expensive for just a replaced light, it makes a big difference. It's so much brighter than the stock dome light, but not so much so that it hurts your eyes or is obnoxious. The blue light gives the car a really cool effect at night and turns some heads. The install is an easy plug-n-play which was great for a dope like me. Oznium has good customer service and I have been very happy with their product thus far. I can recommend Oznium to anyone interested in buying a LED dome light, but I'm sure with CO_FlyFisher's experience and knowledge, TaskLED is just as good a choice as well.

Thanks FlyFisher, I cant wait to get these in and use them this summer camping. Its great to support a small business and have lights that won't drain my battery, even after a couple days.

the LED array is definitely the way to go. i bought one for the center dome and rear cargo light and they are great.
oznium is the way to go for those.
took all of five minutes to install.

The TaskLEDs will fit in my 96 dome light right? Thought I should make sure before I purchase a couple.

According to the OSRAM Sylvania Lamp Replacement Guide, it looks like it should. The DE3022 is just 2mm shorter than the DE3175 the newer 4Runners use. There is usually more than enough play in the springs that hold the bulbs to make up for that. You could also trim the contacts on the TaskLED modules a little bit if necessary.

To install the TaskLED module, just remove the old festoon bulb (glass tube with metal ends), and replace with the module. If you want to install the LED array, you find the matching plug end (I cut mine off and had it hard wired in my other vehicle) which looks like the festoon bulb, and plug it in the the array, then install as usual.

Also, since LEDs are polarity sensitive, if it doesn't work plugged in one way, flip it around and it should work fine.

One thing I didn't mention is that the LED array flashes a bit while starting the vehicle. This is because they're "direct-drive" off of the electrical circuit and the starter is pulling so much juice from the battery to turn the engine over.

The TaskLED modules don't do this due to their electronic regulation. As the voltage drops, they pull more current to make up for it and keep constant output.

So with the LED on the right you just put it in the same way you do a regular bulb?

Well shoot.

So it's about the size of a BA9 you say?

I might have to try it in my map lights.

Are they pricey?

Just ordered a couple TaskLED dome modules. I'll take some before/after pics once I get them!

NO, they're the size of the festoon DE3175 in the DOME and cargo light. Like this one: DE3175

The Ba9s is a totally different bulb (look here). The TaskLED modules would easily fit into the space the map lights occupy, but you would need to figure out a way to get power to them and how to mount them.

You'll be amazed how much light comes out of that TINY little LED! :awais:
