The Diode Dynamics SL1 is a crowd favorite, made in the USA with a good track record for being powerful and reliable. I was very pleased to find this bulb perform well in this test.
The OEM halogen bulb produces 390 max lux in this test and the Diode Dynamics SL1 produces 1,290 max lux at 25 feet – now that is a massive increase in light output. Also, you’ll see that the DD SL1 has a significantly more “warm” colored white light than the other bulbs used in this test. The theory here is that the more yellow in the color will help with driving in fog, snow, rain or dust.
Xenon Depot Xtreme LED: 1,090 Lux
The Xenon Depot Xtreme LED headlight bulbs had a focused hot spot but it was an overall scattered beam pattern compared to others and a little taller than others. What this bulb is missing in this particular headlight housing is a more concentrated hot spot, and less lighting down low. The light that hits the ground immediately in front of the truck will create excess foreground illumination which creates an effect that limits your long-distance visibility. These are some of the highest quality bulbs and we’ve seen them test much better in other applications, specifically projector headlights.
The Xenon Depot Xtreme LED bulbs feature extremely high build quality with an innovative and unique flexible heat sink design unlike anything else I’ve seen.
OEM Halogen bulb: 390 max lux. Xenon Depot LED bulb: 1,090 max lux. this beam lacks focus at the hot spot, has some shadowing in the sides and the lower portion of the beam, and is a little over 200% brighter than the OEM bulb.
VLEDS Micro Evolution: 1,100 Lux
The new Micro Evolution LED headlight bulbs from VLEDs claim 3,500 Lumen per bulb, but from the looks of this test, I’m not sure that’s accurate. Xtreme Depot claims 1,790 Lumen and their Lux number is almost identical to VLEDs in this test; Diode Dynamics claims 1,630 Lumen per bulb and they’ve got over 100 more Lux than VLEDs in this same test. So where do VLEDs get their Lumen numbers from? The beam pattern from this bulb left some things to be desired as well, not to be a bully but just look at it! The hot spot is 20% lower in the beam than where it should be (causing massive amounts of glare to other drivers) and the main body of the beam pattern has these kinds of “steps” on either side as it descends to the road. It’s definitely not the worst out there, by a long shot, but definitely not the best either.
The Micro Evolution bulb is small… really small! It should fit just about any application out there. It seems to be built well but the difference between the claimed Lumen rating, and its actual usable Lux rating tells a different story.
The original halogen bulbs created 390 maximum lux at 25 feet, and the VLEDs Micro Evolution LED bulbs created 1,100 maximum lux at 25 feet with a pure white, 6,000k – looking color.
The beam pattern from the Putco F1 LED headlight bulb was one of the best of the whole lineup, it just wasn’t even close to the brightest. The color is a very nice looking 6,000K bright white color, the hot spot is well defined, and there are no shadows or weird shapes in the beam pattern. Just a full, smooth beam from top to bottom with little glare above the cutoff. These bulbs use a metal flexible heat sink that allows them to fit inside of almost any headlight housing on the road, they’re affordable and produce a good beam pattern. These ones are definitely worth looking at!
The OEM Halogen bulb created 390 maximum Lux at 25 feet from the wall and the Putco F1 created 1,190 maximum lux at 25 feet away. This is almost exactly a 300% increase in brightness over stock, and it’s one of the best beam patterns I tested here.
This bulb features Philips Z ES CSP style LED chips that mimic the beam pattern style of the original halogen filament light bulb. This allows them to create a great beam pattern in most applications.
Car Lighting District Helios: 920 Lux
The gold-colored CLD bulbs came in at about 2.5X the brightness of the original halogen bulb but the beam pattern was a problem. Not only was the hot spot ill-defined, but it also moved down in the beam pattern compared to the original halogen beam. My other complaint about this bulb, that in typical CREE XHP50 fashion, the beam pattern turned into a massive block of light, a giant glare-filled light output set to dazzle oncoming drivers. This is the type of bulb technology that gives all-LED headlight bulbs a bad name! See, the problem is that a great big single LED chip, albeit bright, doesn’t mimic the original incandescent filament light source well enough to retain a good beam pattern. This thing is kind of like having a small LED offroad light bar inside your headlight. No more driving beam, now you have a flood beam!
The Helios LED bulb from CLD is about what you would expect from a single large SMD style LED chip like the XHP50 used in this application. Large and in charge, tons of light, but no focus. It’s not even really that bright compared to some of the other options tested. The original halogen bulb beam created 390 maximum lux at 25 feet from the wall, and this CLD Helios LED created only 920 maximum lux at 25 feet. CLD claims these bulbs produce a laughable 12,000 Lumens… LOL. Either they’re lying to us, or their design is massively inefficient.
The long-awaited Morimoto 2Stroke 2.0 LED headlight bulb is here and it’s pretty good! In this test, this bulb created a 217% increase in light output over the original bulb, the color is great, they are super easy to install and the beam pattern isn’t too bad. The thing I look for in evaluating the beam pattern has to do with the definition of the hot spot (should be high and tight in the center), the shadows and weird shapes (or lack thereof) in the beam pattern on the wall, and the height of the beam. The beam shouldn’t be very tall, the taller the beam pattern the more foreground light you get which sacrifices your long-distance vision.
The Morimoto 2Stroke 2.0 LED headlight bulbs are a great fit in the new 2019 Ram reflector halogen headlight. It’s able to be adjusted easily to clock perfectly in the housing and I love the color!
The original halogen bulb created 390 maximum lux (max usable brightness) at 25 feet and the new Morimoto 2Stroke 2.0 LED headlight bulbs came in at 1,240 max lux.
CrystaLux G9: 1,210 Lux
The CrystaLux G9 bulbs use a flexible metal heat sink similar to the one found on the PutCo F1 but the material is different. The LED chips are the popular Luxeon Z ES models and overall this bulb has a high build quality. The majority of the brightness was on the top half of the beam pattern and the hot spot itself was right up there next to the cutoff line. This bulb had a higher-than-average beam pattern and it was brighter than some but nowhere near the brightest of the group.
This LED headlight bulb from Crystalux has a low profile design to fit almost any headlight application and in all fairness, it’s a pretty good option.
The beam pattern from the CrystaLux LED bulbs was very good. Nice clean color, good hotspot and a tight overall beam pattern vertically. It has some shading in the beam, so it’s not as good as it could be and those lines and shadows could become a distraction while driving. The original halogen bulbs created 390 max lux and these bulbs came in at 1,210 max lux in this particular test.
DDM Tuning RaptorLED: 1,000 Lux
The DDM Tuning Raptor LED headlight bulb is probably the worst one I tested in this batch! Super cheap-feeling bulb, the usable light output was greater than stock by a lot, but the beam pattern was so terrible!! See for yourself below. Somehow they managed to put the hot spot in THE CENTER of the beam pattern… The amount of stray beams of light, shadows, and streaks in this output is flat-out dangerous. This WILL blind another driver on the road and in my humble opinion, DDM Tuning should pull these bulbs off Amazon as soon as possible! DANGER WILL ROBINSON
You can find most DDM Tuning LED headlight bulbs on Amazon at a discount, and this “Raptor” bulb is no different. Coming in at a whopping $64, and claiming a ridiculous 5,500 Lumens of light output! More like 500 lumens…
Isn’t this just terrible? Go back up and look at the original halogen bulb, then come back here. What a terrible change. I seriously feel sorry for anyone who spends their hard-earned money on this product. The original halogen bulbs created 390 maximum lux in our 2019 Ram test and these DDM Tuning Raptor LED bulbs came in at 1,000 Lux. The worst beam pattern, and one of the worst brightness levels too… RUN!
The DDM Tuning Raptor LED headlight bulb is one you want to stay away from for your 2019 Ram truck. It is built poorly with old technology, it feels cheap, and the beam pattern it creates is downright dangerous!
