The JW Speaker 8800 is, in our experience, the world’s best and most popular sealed beam 4×6 LED headlight replacement. You see these on some older cars, but mostly they show up on RVs and semi-trucks that need a serious upgrade over the old incandescent units. What makes the 8800 Evolution 2 really special is that it is the world’s first 4×6 LED headlight to come with an optional heated lens, and in this article we are going to walk you through exactly how that heated lens works and how well it performed when we put it through our own heat and ice melt testing.
If you have ever driven your truck through Alaska or over a mountain pass, you already know why this matters. Frost, ice, and snow build up on your headlights and cut down your light output fast. That is the whole reason the heated lens option exists, and it is a genuinely big deal for anyone driving in a cold climate. We tested the heated version against a traditional incandescent sealed beam to see if the LED could really keep up when the temperatures drop.
What the JW Speaker 8800 Actually Is
Before we get into the testing, it helps to understand what category this product falls into. The 8800 is a direct replacement for the old 4×6 rectangular sealed beam headlights that came stock on countless vehicles. If you are not sure exactly how these compare to the original units, we put together a full breakdown of what a sealed beam headlight actually is that is worth a read before you buy anything.
Because the 4×6 format is so common, there is a whole world of upgrade options out there. We carry a full lineup of sealed beam headlights for trucks and cars, and if you want to narrow it down to just this size you can shop all 4×6 sealed beam options in one place. The JW Speaker 8800 sits at the top of that list for a reason, and the heated lens is the feature that really sets it apart from everything else.
Style and Configuration Options
The 8800 comes in a couple of different styles so you can match the look of your rig. You get a chrome high beam, a chrome low beam, a black high beam, and a black low beam. On top of those finish and beam choices, you can order each one with the heated lens or without it. The heated lens version does cost a little more money, but as you will see from our testing, it is absolutely worth it if you deal with snow and ice.
If you want to see the full specs, pricing, and pictures for every configuration, you can check out the JW Speaker Model 8800/8800H with SmartHeat Tech right on our website. It is the easiest way to make sure you are ordering the exact finish and beam function your vehicle needs.
How the Heated Lens Works
There are two things that set the heated lens version apart from the standard 8800. The first is obvious the moment you look at it: the defroster lines built right into the lens. These are the lines that actually melt the snow and ice off the front of the headlight, similar to how a rear window defroster works on a car.
The second difference is how the system decides when to turn on. On the far side of the housing there is a vertical sensor that measures the outside temperature of the headlight. That sensor tells the defroster when to turn on and when to turn off, so you do not have to manually flip a switch every time the weather changes. When it is actively heating, you get an LED indicator that lets you know it is doing its job.
Heat Test: LED vs Incandescent Sealed Beam
One of the most common concerns we hear about LED headlights is that they run cooler than the old incandescent bulbs, and people worry that a cooler headlight will not melt snow off the lens the way the hot incandescent units used to. So we set up a straightforward test. We powered up one of the heated lens 8800s, ran it for five minutes, and measured the average temperature of the unit. Then we did the same thing with a traditional incandescent sealed beam headlight so we could compare them side by side.
After five minutes, the incandescent sealed beam gave us readings all over the place. We saw numbers like 94 and 102 around the edges and 125 to 128 in the center. When we averaged everything out, it landed at about 115 degrees Fahrenheit, with one spot reading as high as 123 where we finished measuring.
Then we looked at the JW Speaker 8800 heated LED. We were seeing readings like 105, 115, 114, and 111.2. When we averaged those out, it came in right around 110 degrees. That is essentially the exact same temperature as the incandescent light. In other words, the LED heated lens is not running cold at all. It matches the old sealed beam almost perfectly.
Frozen Lens Melt Test
Measuring surface temperature is one thing, but we wanted to see the heated lens actually go to work on real ice. So we took one of these headlights, put it in the freezer overnight, and covered it in water so it would freeze solid. By morning there was frost all over the place and chunks of ice sitting right on the lens.
When we started the test, the lens was sitting at about 19 degrees. We powered it up and watched how quickly the heated defroster could bring it up to temperature and clear the ice. At the one minute and 45 second mark, the light had already reached an average temperature of 59 degrees Fahrenheit. That is a huge jump in a very short amount of time.
By about the two minute mark, you could tell the frosty lens did not stand a chance. The ice was visibly breaking up and running off the front of the headlight. At three minutes, we were pretty much completely melting all of the ice and snow that had built up overnight.
Is the Heated Lens Worth It?
Putting both tests together tells a clear story. Before the five minute mark, both the LED headlight and the incandescent sealed beam reached an average temperature around 110 degrees. So if you are worried that a 4×6 LED will not melt snow as well as the original incandescent unit, the heated lens version from JW Speaker puts that concern to rest. It reaches the same lens temperature as the old sealed beam, and it does it while giving you all the other benefits of modern LED lighting.
The heated lens option does cost a bit more than the standard version, but for anyone driving in cold climates, we think it is money well spent. Being able to keep your headlights clear of frost, ice, and snow is a genuine safety upgrade, not just a convenience feature.
Other 4×6 Options Worth Considering
The JW Speaker 8800 is our top pick in this size, but it is not the only quality option on the market. If you want to compare it against another premium bi-LED unit, the Morimoto Sealed4 Bi-LED 4×6 housing is another well built choice, though it does not offer the same heated lens technology. And if you are cross shopping different sources, you can also find the JW Speaker Model 8800/8800H at The Retrofit Source. We still recommend grabbing yours through us so we can help you get the exact configuration dialed in for your vehicle.
Whether you are upgrading an old car, an RV, or a semi-truck that needs to run reliably through winter, the JW Speaker 8800 Evolution 2 with the heated lens is one of the most impressive 4×6 replacements we have tested. It matches the heat output of a traditional sealed beam, melts ice fast, and does it all with the automatic temperature sensor doing the thinking for you.
