Why you should trust this review
I have run a UniFi network at home since 2018, currently consisting of a UniFi Dream Machine Pro, three UniFi 6 access points, four cameras, and three switches. The UniFi Switch Lite 8 PoE was bought at retail in March 2025 to replace an older USW-8 (non-PoE) and consolidate camera power into one switch. Ubiquiti did not provide a sample.
I am writing this review because the UniFi Lite 8 PoE is the cheapest legitimate way into PoE-managed networking, and a long-term review matters more than a launch-week post.
How we tested the UniFi Switch Lite 8 PoE
- 10,300 logged hours of uptime over 14 months
- iPerf3 throughput across all 8 ports simultaneously
- PoE budget tested with a mix of UniFi G4 Bullet, G5 Pro, and U6 Lite access points
- VLAN topology validated through the UniFi controller with four VLANs
- Power draw measured with a Kill A Watt P4400 at idle, under load, and with full PoE budget engaged
- See our methodology for full protocol
Who should buy the UniFi Switch Lite 8 PoE?
Buy it if:
- You already use or plan to add UniFi access points or cameras
- You need 4 PoE+ ports for a small home setup
- You want enterprise-grade reliability and a polished controller UI
- You appreciate fanless silent operation
Skip it if:
- You do not own and will not own UniFi devices, the price premium is hard to justify
- You need more than 52 W of PoE budget, look at the USW-Lite-16-PoE
- You want a managed switch without the controller dependency
Throughput: line rate on every port
iPerf3 between four port pairs sustained 936 Mbps on every link. The 16 Gbps switching capacity is well above what eight 1 GbE ports can saturate. VLAN tagging adds no measurable overhead. The hardware is identical in switching performance to the TL-SG108 and GS308E, the differentiator is purely the PoE and management features.
PoE budget: enough for a small home
52 W total is the right size for a home setup with two APs and two or three cameras. We ran the following config without trouble:
- 1x UniFi U6 Lite AP (12 W)
- 1x UniFi U6 Pro AP (15 W)
- 2x G4 Bullet cameras (10 W total)
- Total: 37 W active, 15 W headroom
For larger setups (more cameras, more APs), the USW-Lite-16-PoE has a 60 W budget across more ports. For households running G5 Pro cameras, 52 W gets eaten quickly.
UniFi controller integration: where the price tag earns out
This is where the Lite 8 PoE separates from a $39 lite-managed switch. The UniFi Network Application gives you a single-pane-of-glass topology view across switches, APs, cameras, and gateways. Per-client traffic graphs, VLAN tagging via port profiles, link aggregation, port mirroring, and remote management are all in one place.
If you only have one switch, this is overkill. If you have or will have multiple UniFi devices, having them all show up in one controller is what makes UniFi appealing.
Reliability over 14 months
PRTG and the controller’s own uptime tracker logged exactly zero unscheduled reboots over 14 months. Two scheduled firmware updates, both applied cleanly without traffic loss. PoE delivery has been rock solid: cameras and APs have not lost power once outside scheduled reboots.
Power and noise
Idle draw without PoE engaged is 5.1 W. With our 37 W camera and AP load, total draw is roughly 47 W. The fanless metal chassis runs at 41 to 44°C surface temperature under that load, well within safe range. Truly silent.

Should you buy the Ubiquiti UniFi Switch Lite 8 PoE?
The UniFi Switch Lite 8 PoE is the right way into the UniFi ecosystem if you have or plan to add UniFi access points and cameras. Four PoE+ ports with a 52 W budget cover most home camera and AP setups, the UniFi Network controller integration is excellent, and the build quality is enterprise-grade. The catch is the price: at $119 it costs five times more than the [TP-Link TL-SG108](/reviews/tp-link-tl-sg108). Worth it for UniFi households, overkill for everyone else.
Frequently asked questions
Is the UniFi Switch Lite 8 PoE worth $119 in 2026?+
Only if you already use UniFi access points or cameras, or plan to. Without other UniFi devices, the [Netgear GS308E](/reviews/netgear-gs308e) at $39 covers most lite-managed needs and the [TL-SG108](/reviews/tp-link-tl-sg108) at $24 covers basic switching.
Do I need a UniFi controller to use it?+
Yes for full features. You can run the UniFi Network Application as a Docker container, on a Raspberry Pi, or on a UniFi Cloud Key Gen2. The switch will pass traffic without a controller but VLAN, port profiles, and LAG configuration require one.
How many cameras can I run on it?+
Depends on each camera's PoE draw. Four UniFi G4 Bullet cameras (5 W each, 20 W total) leave 32 W for two APs. Four G5 Pro cameras (12 W each, 48 W) only leave 4 W in the budget, so plan PoE budgets accordingly.
UniFi Switch Lite 8 PoE vs USW-8: what's the difference?+
The Lite 8 PoE has 4 PoE+ ports at 52 W total. The USW-8 (non-PoE) has zero PoE. There is also a USW-Lite-16-PoE for larger setups. Pick the model that matches your PoE device count.
Can it run without internet access?+
Yes, the controller can be on a local LAN. UniFi adoption requires the controller to reach the switch over the LAN once, but ongoing operation does not require internet.
