LED Par Can Buying Guide: RGB vs RGBW vs RGBWA Explained
Chia sẻ
The LED par can is the most reused fixture in professional lighting: cheap to own, easy to rig, and flexible enough for wash, uplight and backlight. The one spec that decides how good it looks is the LED color engine. Here is how to choose the right par for your venue, your clients and your budget — and how to size a package that actually covers the room.
What an LED par can is for
A par can throws a broad, even wash of color. Unlike a moving head it stays put, which makes it ideal for coloring a backdrop, a wall, a cyclorama or a row of tables at a wedding. Most models are DMX-addressable and stack neatly in a truss or on a floor base. Because they have no moving parts beyond the fan, they are also the most reliable fixtures in a rental inventory.
RGB vs RGBW vs RGBWA vs RGBWA+UV
| Engine | LED mix | Best for |
|---|---|---|
| RGB | Red/Green/Blue | Budget wash; punchy primary colors, weak whites |
| RGBW | + White | Clean whites & pastels for camera-facing work |
| RGBWA | + Amber | Warm skin tones, amber-rich looks |
| RGBWA+UV | + UV/violet | Blacklight effects and vivid neon |
Rule of thumb: choose RGBW for rentals and broadcast, RGBWA when you want theatrical warmth, and UV only if you run glow parties or need blacklight.
Specs that actually matter
- Channel count — 4-channel (RGBW) is simplest; 8+ gives fine dimmer control.
- Beam / zoom — a 25°–40° lens is the safe default; motorized zoom costs more but covers more rooms.
- IP rating — indoor pars are IP20; pick IP65 for outdoor and wash bays.
- Power & flicker — confirm 100–240V and a high refresh rate if you shoot video.
Sizing a par package by room
The most common mistake is buying too few pars and ending up with visible 'hot spots'. As a starting point, uplighting a perimeter wall needs roughly one par every 2–3 meters. A 6 m wide backdrop benefits from 4–6 pars for even coverage, and a typical 20-table reception wants 8–10 pars distributed around the room. Always buy a couple of spares — pars are cheap and a dead fixture in a wash row is obvious.
Power, cabling and rigging
Most LED pars draw 30–120W each, so a 20-par rig rarely exceeds a single 16A circuit — but total the wattage before you load a dimmer or generator. Use IP-rated powerCON or Edison connectors for tour builds, daisy-chain DMX with a terminator on the last unit, and secure floor pars with sandbags so they cannot be kicked over mid-show.
Common mistakes to avoid
- Buying RGB-only pars for a rental house — clients will ask for white and you cannot deliver it.
- Mixing brands with different color calibration — the wash looks patchy across the room.
- Forgetting the beam angle — a narrow lens cannot wash a wide wall without gaps.
Where par cans earn their keep
Theaters use them for backwash, AV companies for room uplighting, and churches for soft front color. They are also the cheapest way to light a press wall or a product reveal.
Recommended GFlight par cans
- 54x3W RGB LED Par Can — a high-density RGB workhorse.
- 18x18W 6-in-1 LED Par Can — six-in-one color for smooth mixing.
- 4-in-1 Waterproof Par Light — IP-rated for outdoor builds.
- 100W COB Warm White Par — clean white for camera-facing wash.
Installing and focusing your pars
Floor pars should sit low and aimed up the wall at a steep angle so the color lands evenly without a hot spot at the base. Truss-mounted pars aim down and across. Focus during the empty room, then walk the perimeter to check for gaps. A small piece of gaff tape marking each par's DMX address on the fixture saves the next setup a full re-focus.
Rental care and storage
Pars are tough but lenses scratch and fans clog. Wipe lenses after every gig, store in padded cases, and label cables by length. Keep a few spare gel-free units on the shelf so a single failure never breaks a wash row. Track each fixture's show count — after a few hundred gigs, LED output and fan noise both drift and it is time to retire or refurbish.
Par can accessories worth stocking
A few cheap accessories multiply a par's usefulness: diffusion filters for a softer wash, barn doors to shape the beam, and clamp adapters for different truss sizes. A small flight case of accessories turns a basic par into a flexible tool and saves a return trip when a client asks for a look you didn't pre-plan.
Frequently asked questions
Do I need RGBW if I only do parties?
For club and mobile-DJ work RGB is fine, but RGBW gives you clean white for the slower songs and looks better on camera.
How many pars for a small stage?
A 4–6 m wide backdrop usually needs 4–6 pars; uplighting a room of 20 tables needs roughly one par per 2–3 tables.
Can pars live outside?
Only IP65-rated pars should. Indoor IP20 units will fail in rain or heavy condensation.
Can I mix LED pars with older tungsten fixtures?
Yes, but match the white point: set the LED pars to the same CCT as your tungsten units (around 3200K) so the wash blends instead of showing two different whites.
What beam angle should I buy?
A 25°–40° lens is the safe default for most rooms; buy a few narrower units only if you specifically need long-throw washes on large stages.
