SurgeFX SF-BP918 IP65 Battery-Powered LED Par Light

What the BP918 Does

The SF-BP918 is a battery-powered LED par light — a fixture that washes surfaces, objects, and spaces with colored light without any cables. Built-in rechargeable battery for power, built-in 2.4G wireless DMX receiver for control signal, and WiFi for smartphone app control. Place it on a floor, a table, a ledge, behind a hedge, under a tent, at the base of a tree, on a ceremony arch — anywhere you want colored light — and walk away. No extension cords, no DMX cables, no gaffer tape.

RGBWA+UV — Six Colors in Every LED

Each of the 9 LEDs contains six independent color emitters: Red, Green, Blue, White, Amber, and Ultraviolet. This 6-in-1 architecture means every LED can produce any combination of those six colors simultaneously, unlocking a color palette far beyond basic RGB:

Why 6-in-1 Matters

A standard RGB par can mix red, green, and blue to approximate most colors, but it struggles with two things: warm whites (RGB white always looks slightly cold or pinkish) and amber/gold tones (RGB can't produce true amber — it produces a yellowish-green that doesn't look right). The dedicated White and Amber emitters solve both problems. When a wedding planner asks for "warm candlelight" uplighting, the BP918 delivers actual warm amber — not an RGB approximation. When a corporate client needs clean white stage wash, the dedicated white emitter provides it without color contamination. And the UV emitter adds an entire dimension that RGB fixtures simply can't access.

Who It's For

The BP918 is built for anyone who needs professional color lighting without cables. Wedding and event professionals — uplighting ceremony arches, tent poles, building facades, and reception spaces where running power cables is impractical or ugly. Mobile DJs — battery-powered uplighting around the dance floor perimeter without trip-hazard cables across walkways. Outdoor event producers — festivals, concerts, garden parties, and poolside events where the IP65 rating means rain won't stop the show. Houses of worship — temporary lighting for outdoor services, processionals, and special events. Venue owners — architectural wash lighting for building exteriors, gardens, and patios where permanent wiring isn't installed. Rental companies — wireless fixtures that deploy fast, survive transport and weather, and scale affordably when you need 8, 12, or 20+ units.

Battery System

Runtime — By Usage Mode

Battery runtime depends entirely on how many LED emitters are active and at what intensity. The more colors and the brighter the output, the faster the battery drains:

Real-World Runtime Planning

Most event lighting doesn't run all six emitters at full blast for the entire event. A typical wedding reception uses warm amber or soft pastel uplighting at moderate intensity — that's in the 10–20 hour range. A DJ party with active color changes and moderate-to-high intensity will land around 6–10 hours. Even the worst-case scenario (every emitter at maximum) still delivers 3+ hours — enough for most performance sets and receptions. The BP918 runs 9 LEDs instead of 12, which means lower total power draw — at equivalent brightness settings, it stretches battery life efficiently.

Three Power Modes

Charging Strategy for Multi-Fixture Kits

For professionals running 6–12 BP918s per event: charge all units overnight (4–5 hours to full). Each unit arrives at the venue with a full charge. For back-to-back events, charge during load-in of the next day's event. For touring or festival use where charging infrastructure is limited, consider a multi-unit flight case with built-in charging for simultaneous charging of all units from a single power connection.

Complete Specifications

BP918 vs WD1218 — Side by Side

Both fixtures deliver the same color quality, the same weatherproofing, and the same wireless control ecosystem. The WD1218 adds 33% more LEDs for higher output in larger spaces. The BP918 is the right choice when you're uplighting at typical event distances (3–10 feet), buying in quantity, or working smaller-to-medium venues where 9×18W provides all the output you need.

What IP65 Actually Means

IP65 means the BP918 handles real outdoor conditions: rain, sprinkler overshoot, dust at festivals, morning dew during overnight installations. It does not mean the fixture can be submerged (that requires IP67+). Don't put it in a pool or leave it in standing water. Rain, wind-driven moisture, and outdoor dust? Handled.

Six Control Modes — All Wireless-Capable

Every control method works wirelessly — no DMX cables required for any mode:

DMX Channel Modes

6-Channel Mode Breakdown

DMX Universe Planning

In 6-channel mode: 85 BP918 fixtures per DMX universe (85 × 6 = 510). In 10-channel mode: 51 fixtures per universe (51 × 10 = 510). For typical uplighting deployments of 8–20 fixtures, one universe handles everything with room to spare for other fixture types.

Auto-Run Programs

Built-in auto programs work without any controller: color fade (smooth gradual transitions), color jump (sharp color changes), color strobe (flashing effects), and static color hold. Speed and brightness are adjustable from the onboard LCD display or the IR remote. Programs cover the most requested event colors — warm amber, cool white, deep blue, emerald green, magenta, lavender, UV, and dozens of mixed tones.

Frequently Asked Questions

Can I use this in the rain?

Yes. IP65 is specifically rated for water jets from any direction — rain is well within its protection level. The housing is sealed, connectors are IP65-rated waterproof, and all electronics are protected. What IP65 does not cover: submersion, standing water, or pressure washing. Don't put it in a puddle or a pool. Rain, snow, sprinklers? No problem.

How long does the battery actually last?

It depends on your color and intensity. Single warm amber at moderate intensity: 15–20+ hours. Mixed colors at medium brightness: 6–10 hours. Full RGBWA+UV at maximum: 3–4 hours. For a typical 4–5 hour wedding reception using warm amber uplighting at 60–70% intensity, you'll have battery to spare.

Can I use it while charging?

Yes. The BP918 operates on AC power while simultaneously charging the battery. Seamless transition between battery and AC — no interruption to light output.

BP918 or WD1218 — which do I need?

Same color system, same weatherproofing, same wireless controls. The WD1218 has 12 LEDs (33% more output) for bigger throws and brighter environments. The BP918 has 9 LEDs — more than enough for typical uplighting distances of 3–10 feet. If you're buying 8–16 units for an uplighting kit, the per-unit savings on the BP918 add up significantly. If you're lighting large architectural surfaces at 15+ foot throw distances, the WD1218's extra output is worth the step up.

What wireless DMX transmitter do I need?

The BP918 has a built-in 2.4G wireless DMX receiver. It's compatible with standard 2.4G wireless DMX transmitters from most professional brands. Connect the transmitter to your DMX controller's output, pair it with the BP918s, and you have wireless DMX control.

Do I need the WiFi app?

The WiFi app is one of six control options — it's not required. You can control the BP918 with the included IR remote, the onboard LCD display, wireless DMX, wired DMX, sound-active mode, or auto-run programs. The app is the most convenient for quick event setups, but every function is accessible without it.

How many do I need for a typical event?

For uplighting: one fixture every 8–12 feet of wall space, or one per architectural feature (column, tent pole, window bay). Typical wedding reception: 8–12 fixtures. Large tent: 10–16. Small venue: 4–8. The 30° beam angle provides moderate spread, so fixtures at 8–10 foot intervals create even overlap for continuous wash coverage.

Is the UV strong enough?

Yes. The UV emitter activates fluorescent materials, UV-reactive paints, white clothing, and UV-reactive decor at typical uplighting distances. For maximum UV effect, dim the other emitters and run UV only — the less visible light present, the more dramatic the glow.

Setup Tips

Charge the Night Before

Make it part of your load-out routine: when you return from an event, plug in all BP918 units before leaving the shop. 4–5 hours to full charge means they're ready long before your next load-in.

Use the IR Remote for Quick Color Matching

When a client points at a linen swatch and says "match that," the IR remote is your fastest tool. Scroll through preset colors, find the closest match, fine-tune with the individual RGBWA+UV controls on the LCD display. Once dialed in, set all other units to match via master/slave or the WiFi app.

Master/Slave for Uniform Uplighting

For events where every uplight needs to be the exact same color (the most common uplighting scenario), master/slave mode is the fastest deployment. Set one fixture as master, dial in the color, all slave units match automatically. No DMX controller needed. No WiFi app needed. No programming needed.

Start at 70–80% for Longer Runtime

Most clients can't tell the difference between 80% and 100% intensity, but the battery runtime improvement is significant — you might gain 2–3 additional hours. If the venue offers any power outlets near fixture locations, plug in those units and run the rest on battery.

IP65 Doesn't Mean Careless

After outdoor events in wet conditions: wipe fixtures dry before storage, check that connector caps are seated, and store in a dry environment. Salt spray (coastal events) and chemical exposure (pool decks) should be rinsed with fresh water. The IP65 seals protect during operation — long-term corrosion prevention requires basic post-event care.

Pairs Well With

• SF-WD1218 — Mix BP918s and WD1218s in the same kit. Use WD1218s for high-output positions (long throws, feature walls) and BP918s for closer uplighting. Same color system, same controls — they blend seamlessly.
• Cold Spark FX — Colored uplighting behind cold spark fountains creates dramatic reveals.
• Fog FX — Low fog with colored uplighting creates a glowing cloud effect on the dance floor.
• Haze FX — Light atmospheric haze makes beam paths visible and adds depth to color washes.
• Moving Heads — The BP918 is the color wash foundation. Layer beam effects (BM100, BM60, SP90) over your uplighting for dynamic contrast.
