Low Power vs High Power LED Bulbs

Should you choose low power LED bulbs or high power LED bulbs?

I tested several GTR Lighting LED bulbs against competing brands to see how they really perform. The differences were obvious. Not all LED bulbs deliver usable light. In fact, some barely improve over stock.

If you want premium performance, you need more than marketing claims. You need real output, proper beam spread, and solid construction.

Let’s break it down.

1156 LED Bulb Comparison: StreetGlow vs GTR Lighting

When you compare the StreetGlow 1156 LED to the GTR Lighting 1156 LED, the differences jump out immediately.

StreetGlow uses twelve small 3mm dome-style LEDs. Manufacturers typically use these chips for dash indicators or switch lights. They only fire forward. Once installed behind a red tail light lens, much of the light disappears.

The StreetGlow bulb also uses a bulky mushroom-shaped metal base. That design can cause fitment problems in tighter 1156 or 1157 sockets.

In contrast, the GTR Lighting 1156 LED uses seven high-power 5050 SMD chips. Each chip contains three diodes. More importantly, the bulb produces true 360-degree output.

That side-firing light matters. Most tail light housings rely on reflectors to distribute light. Without side emission, the housing cannot function correctly. Instead of a full pattern, you get a weak hot spot.

The GTR bulb also features a tapered design that fits more socket styles with ease.

Pricing:

• StreetGlow 1156 (pair): ~$28

• GTR Lighting 1156 (pair): ~$75.90

The cheaper bulb costs less upfront. However, the performance gap is massive.

194 / 168 LED Bulb Comparison: Old Tech vs Modern Output

Next, let’s look at the 194/168 size.

StreetGlow uses a single inverted 5mm LED chip. While it directs light forward, it produces very little output. Behind a colored lens, it struggles even more.

StreetGlow claims these bulbs offer “greater illumination.” Real-world testing tells a different story. The light output remains weak and narrow.

Meanwhile, the GTR Lighting 194/168 LED uses five high-power 5050 chips. One faces forward. The others fire outward. This creates balanced, usable 360-degree light.

As a result, reflector housings perform properly. The light spreads evenly instead of forming a tiny dot.

The GTR version runs significantly brighter while still producing minimal heat.

Pricing:

• StreetGlow 194 (pair): ~$9.99

• GTR Lighting 194 (pair): ~$33.00

Again, you get what you pay for.

7440 / 7443 LED Bulb Comparison: Plasmaglow vs GTR Lighting

Now let’s examine the 7440/7443 size.

Plasmaglow uses nine faint 3mm dome LEDs, all facing forward. The clear plastic housing looks flashy, but output remains weak. These bulbs cannot safely or effectively replace OEM bulbs in many applications.

Despite brand visibility and SEMA affiliations, performance still matters most.

By comparison, the GTR Lighting 7440/7443 LED uses four high-power 1.5W flat LED panels. Each panel contains three chips. That equals six watts of usable power and twelve surface-mount LEDs.

The bulb produces full 360-degree output. It also uses a durable plastic base and aluminum top for better heat control and longevity.

Pricing:

• Plasmaglow 7440 (pair): ~$18

• GTR Lighting 7440/7443 6W (pair): ~$75.90

The difference in output is not subtle. The GTR bulb delivers real performance.

Why 360-Degree Output Matters

Many budget LED bulbs only fire forward. That design limits reflector performance.

Automotive housings depend on side-emitted light to reflect and distribute illumination. Without that light, the housing cannot function as designed.

High power LED bulbs that emit light in all directions maximize reflector efficiency. You get better brightness, cleaner spread, and improved visibility.

Conclusion: Performance Over Price

Some buyers chase the lowest price. However, cheap LED bulbs often produce disappointing results. Spending $20 on a weak bulb does not improve your vehicle.

If you care about brightness, quality, and durability, invest in high power LED bulbs with modern chipsets and proper 360-degree output.

When you upgrade your vehicle, aim for real improvement—not a cosmetic change.
