Review on SEALIGHT L2 9007/HB5 LED Bulbs With 24000LM, 800% Brightness, Turbo Fan, Plug And Play, 6000K Cool White, Pack Of 2 by Mark Glass

Just got these today & got them installed. Cord coming out of top side made mounting regulator easier than previou bulbs, the Xenower x2 H4.Beam is cleaner with less unwanted stress light than previous bulbs listed above. Part of the stray light I blame on the after market light fixtures as Toyota ones seemed cleaner in stray light department. Unfortunately these were what I could afford. These fixtures look exactly like stock but perform differently in terms of beam pattern. There are definitely some dead spots in beam pattern in these fixtures which I believe would not have been issue with stock housings unfortunately stock housings were a bit hazy & yellowed even after cleaning up lens & polishing.High beams have narrow vertical dispersion with almost no light below what appears to be a somewhat soft cutoff line. Only small excursions below that line near central hot spot. Central hot spot is where these lights take the cake compared to the obviously otherwise brighter Xenower X2. The hot spot here is more intense with the new bulbs as light is more sharply focused than the Xenower X2Bulbs run cooler than previous bulbs & muck cooler than the Laxmas L1 bulbs due to these having external regulator where as the L1 had internal regulators. The L1 would get so hot after less than a minute that it was hard to touch any part of heatsink for even 1/4 second. These I can touch & hold on to heat sink even after 5-10 minutes. Regulator gets hot but not unbearably after 10 minutes. These should last much longer than the L1 since heat cycling will take much longer & run cooler even at peak temperature.Observations of basic bulb design. These bulbs are listed as having a slightly thicker copper board than the L1 but in practice visually the L2 looks thinner than L1. Also the LEDs appear to also be slightly thinner vertically but have somewhat greater width with more white area exposed beyond the yellow LED die area. I believe this contribute to an observed slightly wider stray light area above cutoff than there was on the L1. This is caused by the reflective barrier that is used to limit light from reaching lower part of fixture reflective light bowl on low beam & reflecting it upward in attemp to fill in lower central part of low beam. This reflective light barrier reflect some light back onto the white area of the LED chip mounting causing the white area to glow brightly. This was less of a problem on the L1 as LED die mounting was smaller & had less white area outside of the yellow die covering. Bear in mind the stray light area is way better controlled than the stray light coming off the left side of the bulb in the right light fixture that reflects up to the right. The stray light of the X2 was poorly controlled in that area & much better controlled here. There is however some stray light elsewhere on the L2 but is still only a narrow band & none outside that band. To other traffic this would likely cause a more gradual shift in glare between no glare to full on glare going over typical undulations in road. No sudden shifts here. I typically aim my lights so that glare is minimized such that mild undulations in road surface do not cause other drivers to experience full on glare. On cresting hills or more severe undulations some full on glare is unavoidable but I try to make it as minimal as possible within reason.Pictures to come later.Forgot to mention hot spot appears kind of bluish & on low beam the area below hot spot is yellowish looking. High beam is just opposite with yellowish area above hot spot but much less intensity as far as the yellowing of light. High beam is extremely intense, much more so than low beam.Also now that it is getting dark I can see a small amount of stray light I didn't notice before above hot spot on low beam that extends above the cutoff. It is a soft looking stray light however. It appears that it would shoot above people's eyes though.Went out on very dark road tonight & tried these lights out on a dark very lightly traveled road. Low beam is not something you want to use unless you have to on a dark road. Especially not these. Right side of road is fairly brightly lit but left side is limited to about 30 feet if properly aimed. The lane in front of you is lit up to 60-75 feet in front where the cutoff line meets road. This is how I aim them & this puts center of high beam exactly parallel to the rad surface.You remember me saying about the limited vertical dispersion of light on high beam. It is also somewhat limited horizontally but not so much to be a problem. This keeps light near you from becoming overly bright & causing pupils from closing down & limiting distance viewing. This is where these lights absolutely are the cats meow, you can see a very long distance with these lights. However because of thier distance focus the hot spot is very intense & white reflecterized speed limit signs for example are blindingly bright, brighter than many oncoming headlights. Note, I do not use high beam if anyone is in view even if a mile away.Low beams adjusted like I have done will not blind anyone. In fact even cars in front of me that I am following behind do not even show reflection of my lights once 200-300 feet away. Not even the reflectorized license plate is visible from that distance if directly in front or to left of me on multilane road.I added one picture of the x2 on high beam. Note, it is brighter up front but loses by a large margine to the L2 in the distance. This was taken on the same road but positioned slightly different but same reflector group is visible in both. The x2 almost dies by the time it reaches 2 telephone pole but the L2 lights that same pole brightly + lights the tree & some distant poles dimly as well.I changed the low beam picture to reflect what my eyes actually see.I added another picture to show just how incredibly bright these lights are against a speed limit sign on high beam. Those 2 bright lights on the right are actually speed limit signs reflecting my headlights. I even adjusted the exposure as low as I could to make it look like it does in real life. It is just that bright.This is my second attempt to post a video. I think first one may have been to big. This video fairly accurately portrays the brightness, spread of light & how low & high beam look on a very dark road of the Laxmas L2 H4 bulbs in my aftermarket prius fixtures. Stock housing has somewhat different looking beam even though appearance of housing looks identical on surface. These bulbs do quite well especially on high beam. I set & locked the exposure manually to match as closely as possible to real life appearance. As a result this video will not be as bright as others found here of even lower brightness bulbs but this is more accurate. It took a few attempts to get it to look as accurate as it is.
