120% Brighter Lighting - NO Relay Kit Required!
GE (Tungsram) Megalight Ultra +120%
As indicated by their name, GE (Tungsram) H4 bulbs deliver 120% more illumination than a standard 60w/55w H4 bulb. That's 120% brighter with no increase in current draw or heat generated. As a result they don't require the installation of a relay kit as is required by the standard 100/55w H4 bulbs. There is one small compromise - they don't last as long as standard H4 bulbs.
These are a simple plug n' play replacement for your current H4 bulbs. Just remove your old ones and install these (be careful not to touch the bulb part with your fingers). That's it.

Questions & Answers
There are often a confusing number of choices when it comes to buying lighting parts. Our main job is to select and offer to you what we consider to be the best choice based on our extensive research and experience. There are many times when it’s necessary to dig through marketing hype and confusion. For example, there is not always a correlation between price and quality or claims and quality. If we offer it here we have determined that it’s Best-in-Class™️.
Question:
Why do you recommend these when +150 bulbs are available? Aren’t those brighter?
Answer:
This is a perfect example of why surface numbers often don’t tell the whole story. We’re offering the +120s because they provide more light on the road. The +150 has much more blue area on the glass (probably to provide an HID look) which uselessly tints the light while blocking a percentage of it from reaching the road. How much light is blocked by blue tint? Consider the Sylvania ZXE, a fully blue-tinted bulb line:
Actual test results from an integrating sphere:
ZXE H4 Bulb. +130 (12.8 volts)
Without Blue Coating:
Low beam: 1350 lumens
High beam: 2000 lumens
With Blue Coating:
Low beam: 890 lumens = Decrease of 34%
High beam: 1400 lumens = Decrease of 30%
Another factor is that the performance boost shortens the life span of the bulb. And the bigger the boost the more the life span is shortened.
And there’s one more pay-off in dealing with facts. Often times the more flashy the numbers the higher the cost. In this case the Tungsram +120 bulbs are less expensive than the higher plus bulbs - and substantially out-perform them.
Question:
Why not just plug the LED bulb “upgrades” into H4 reflector headlights?
Answer:
Some folks have tried replacing the H4 bulbs in their reflector headlights with LED bulbs and all that accomplishes is blinding on-coming drivers. The reflectors are not engineered for the scattered beams of the LEDs. Perhaps the technology will develop but until them please do not install LED bulbs in your reflector headlights. The Tungsram 60/55w Mega Ultra 120+ are cheaper and - they work.
