Picking a 500W-class bi-color LED monolight in 2026 is harder than it used to be. The GVM AIO 500B and the Nanlite Forza 500B II both target the same buyer — solo creators and small studios who want pro-grade output without hauling around a 720W tungsten — but they solve the problem in two very different ways.
If you have been shopping for the best LED panel lights setup or upgrading to a new monolight, this side-by-side covers what actually matters: output, color accuracy, form factor, and price. I've spent time with both fixtures on real shoots. Here is how they stack up against the best studio lights for photography.

Output figures are from official spec sheets. Always verify the exact lux reading for your reflector and CCT setup before quoting them to clients — fixture output varies a lot with accessories.
Where the GVM AIO 500B Wins
Price-to-output ratio. This is the headline. The AIO 500B publishes 98,300 lux @ 1 m with a Bowens mount for an MSRP of $499. The Forza 500B II costs $1,499 — three times as much — for 67,320 lux. If you are scaling a small studio on a budget, that gap is the entire decision.
All-in-one form factor. The "AIO" in AIO 500B stands for all-in-one: power supply, controls, and lamp head live in a single unit. No control box. No extra cable runs. No second thing to mount on a stand. For solo shooters, run-and-gun interviews, and small studios where you are constantly moving gear, the speed of setup is real.
Wider CCT range. 2700K to 6800K versus the Forza's 2700K to 6500K. That extra 300K on the cool side is small on paper, but it gives you slightly cleaner daylight balance when mixing with overcast windows or HMIs.
More FX presets. 12 + 12 — GVM splits built-in effects into two banks. Realistically you will use six of them; the rest are peace of mind.
Where the Nanlite Forza 500B II Wins
Color accuracy you can hand to a DOP. CRI 96 average, TLCI 97 average, SSI 84 at 3200K. If you are grading log footage or doing broadcast work, the Forza's published TM-30 and SSI numbers are the kind of detail a DP will ask for in pre-production. The AIO 500B's published numbers on these metrics are limited — you will need to test on set.
Control box flexibility. Yes, the AIO form factor is faster to set up, but a separate control box is sometimes what you want. The Forza 500B II head weighs 4.34 kg — a comfortable overhead or boom-arm load for long days. The control unit sits at your feet or on a stand base. Some shooters prefer that weight distribution.
DMX/RDM out of the box. Bluetooth NANLINK is fine for solo work. DMX/RDM matters when you are integrating into a larger lighting plot on set or in a rental house. The Forza speaks the language rental shops expect.
Three-year track record. The Forza 500B II has been in the market since 2023. The firmware is mature, the accessory ecosystem (FL-20G Fresnel, parabolic softboxes, projection attachments) is well-developed, and the brand has proven customer support. The AIO 500B is a 2026 release. Early reviews are positive but you are buying into a newer platform.
Tungsten-Daylight balance correction. ±80 G/M green/magenta shift is a real workflow tool when matching the Forza to other fixtures in a mixed lighting setup.
Who Should Buy Which Monolight
Buy the GVM AIO 500B if:
- You are building a new studio on a budget
- You shoot solo and value fast setup
- You need maximum output for the dollar
- You are OK verifying color accuracy with your own meter
Buy the Nanlite Forza 500B II if:
- You need broadcast-grade color accuracy out of the box
- You work in DMX-controlled lighting plots
- You want a proven accessory ecosystem
- You prefer the weight distribution of a separate control box
Honestly? The two fixtures serve different buyers. The AIO 500B is the "I need pro-grade light and I need it now" choice. The Forza 500B II is the "I am renting this to a DP next week and they will read the spec sheet" choice.
Best LED Panel Light Setups That Pair With Either Monolight
Both fixtures use the Bowens mount, so they slot into most LED panel light workflows — including setups that mix monolights with panel lights led from the same lighting kit. A few real pairings:
- Solo YouTuber or TikTok creator — GVM AIO 500B + a 60×90 cm softbox. Cheap to build, fast to deploy, output is more than enough for talking-head shots. This is the kind of configuration that beats most best led panel lights on the market for head-only budget setups.
- Three-point interview setup — Pair two monolights as key + fill, plus a backlight. The Forza 500B II's DMX/RDM lets you trigger them all from a console, and the LED video light panel in the back can be color-matched to the key. For a compact studio that needs to stay mobile, an LED video light panel mounted overhead rounds out the kit without adding much weight.
- Hybrid photo + video — One monolight through a parabolic umbrella, the other as a rim. Either fixture handles this; the AIO saves you on cable management when the shoot runs into overtime.
- On-location corporate video — AIO on a V-Mount (GVM battery plate) is the fastest setup if your client has a tight shoot schedule. For the more controlled office shoots, professional video lights with proper DMX triggering still have a place, and professional video lights on a DMX console let one operator run the whole scene.
- Best photo studio lights comparison — These two sit alongside the Amaran 100x bi-color LED monolight (smaller 100W form factor) and the 600W-class Aputure LS 600d Pro at the top of the best photo studio lights tier. Buyers looking for the best studio lights for photography should also consider panel lights led setups for soft fill, since panel lights led are easier to diffuse for product and interview work.
FAQ
Is the GVM AIO 500B bright enough for outdoor use?
At 98,300 lux @ 1 m with the reflector, it competes with mid-tier HMIs for daylight balancing. For full sun, you will still want diffusion or a scrim — but so will every other 500W-class LED.
Can I use Nanlite Forza 500B II modifiers on the GVM AIO 500B?
Both fixtures use the Bowens mount, so most softboxes, reflectors, and beauty dishes are cross-compatible. Always check the specific accessory's clamping system before mounting.
Does the AIO 500B have a quiet fan?
GVM lists a low-noise cooling mode, but the published dB rating is limited. If you are shooting in a quiet environment, test it on set first.
Can the Forza 500B II run on battery only?
Yes. It accepts V-Mount batteries at 14.4 V or 26 V. Note that it does not support reverse charging — you cannot run cameras or other accessories off the Forza's battery plate.
Which one is better for YouTube and content creation?
For most solo YouTubers and TikTok creators, the AIO 500B's price and setup speed win. For brand work and commercial content where color accuracy matters, the Forza 500B II is the safer bet.
How do these compare to the best photo studio lights overall? Both fixtures compete in the 500W bi-color bracket alongside other best photo studio lights like the Aputure LS 600d Pro and Godox VL300II. The AIO 500B leads on price-per-lux; the Forza 500B II leads on color accuracy and DMX integration.
