The heat sinks stay cool/warm to the touch while the body of the LED runs warmer. Shy of the 18w spec by my stable temp measurements.Īs with any performance LED, fans keep the units cool. Stable operating temp 1.11A 13.8v, aka these draw about 15.3w. The H11 spec allows for +/- 15% to be compliant, these Philips LEDs are about +8% making them compliant in terms of lumen output (replacement LEDs for headlights are not currently compliant for use on public roads in the US). At this point the Philips product seems mildly underwhelming.Īn H11 bulb is spec'd at 1250 lumens, these LEDs are spec'd at 1350 lumens. For reference Sylvania 2.95mm, Hikari Ultra 2.64mm, Morimoto 2stroke 3.0 2.0mm. Philips 2.85mm width is best in class for major name brands attempting to build a compliant LED product, but fall short of Hikari and Morimoto's latest offerings which both have better (reduced) width. Philips markets these as the first replacement LED on the market to use OEM grade top contact Lumiled LED chips, which should reduce width and increases focus.įirst thing I always check is the width/cross section, which is a key element in focus, which is an important trait for output intensity and distance projection. I haven't seen these available in the US, I ordered these out of the UK. The latest replacement LED headlight 'bulbs' from Philips. However in the 5th Gen T4R projector, the reduced amount of blue coating on the +120s would likely have extra benefit due to the bulbs orientation in the projector. The +130 bulbs are a close 2nd in the 3rd Gen Tacoma projector. So in comparing to an LL bulb if that is what you are running now, the relative gains with performance bulbs will be slightly better.Ģ) Tungsram Nighthawk Xenon +120 are the best performing H11 bulb, but I did not have any of those on hand for the tests. I replaced the LL bulbs with some mildly used Standard Osram H11s from other tests. The 4runner projectors have a much softer and wider blend of light upward above the cut off, which also appears to be lower in intensity.ġ) These assemblies were loaded with Philips Long Life (LL) H11 bulbs, which are lower output and longer life than standard bulbs. The Tacoma has a very distinct box of uplight in the center of each beam pattern directly above the hotspot. The uplight on these assemblies is very different than the Tacoma projectors. Meaning if the cap cannot be reinstalled with an LED, the inside of the projector is at risk of being contaminated with dirt and dust which will greatly reduce performance. But also as shown in the photo below, the projector is not sealed like 3rd Gen. The leading common bi-directional LED blade design seems particularly problematic for these projectors, as the solid metal blade would obstruct output being placed across the projector lens, unlike a transparent halogen bulb. ![]() I'll need to double check, but access in here seems very tight for any type of fan cooled LED. The projectors use a cap/cover on the assembly that must be rotated and removed for access to the bulb inside. The 4runner uses uncommon side entry projectors, where the bulb is placed across/perpendicular to the projector lens rather than inline with it. The 4runner projectors are not that great. For performance bulb upgrades to be most effective it requires precision optics, which goes inline with what has been mentioned before. That 3rd Gen Tacoma projectors respond much more favorably to performance bulb upgrades than the 4runner projectors. The Tacoma has ~34% better peak intensity with 1294 lux vs 1030 lux. ![]()
