Week Aqua P Series LED Review: Budget Full-Spectrum
Week Aqua’s P Series quietly became the budget hero of Singapore’s planted-tank scene around 2023, undercutting Chihiros at every length while delivering surprisingly competent app-controlled spectrum. This week aqua p series led review from Gensou Aquascaping at 5 Everton Park is built from eighteen months of installs across HDB nano cubes and condo show tanks, including two units we ran on bench for sustained PAR drift testing. We will cover what the fixture does well, where it cuts corners, and whether the SGD savings against Chihiros are worth the trade-offs.
What Sits in the Box
The P Series ships with a slim aluminium fixture, low-profile rimless glass clips, a power adapter and a brief paper manual that is best ignored in favour of the app. Build feels lighter than Chihiros, with thinner aluminium and slightly less tactile clips, but nothing that suggests early failure. The integrated controller is housed in the inline brick rather than the fixture itself, which makes mounting cleaner.
PAR and Spectrum Performance
Under a 60 cm tank at 36 cm water depth we measured 110 to 130 PAR at the substrate from the P600 at 100 percent — within 10 percent of a Chihiros WRGB II at the same length. The spectrum is a four-channel WRGB mix, with stock tuning leaning slightly cooler than Chihiros at around 6800 K. Reds render acceptably; greens are bright. For most planted scapes the difference is invisible without side-by-side bench testing.
App Control and Daily Use
The Week Aqua app handles ramped sunrise, sustain and sunset over Bluetooth, with up to four customisable presets. Interface is functional but slightly clunkier than Chihiros, and the connection drops occasionally when phones move out of range mid-edit. As with all Bluetooth LED fixtures in SG, monsoon brownouts can desynchronise the schedule; pair with a smart plug or a budget UPS. Our monsoon aquarium guide covers the protection layer.
Heat and Power Draw
The P600 draws around 60 W at full output and adds approximately 0.5 degrees to a 60 litre tank under 30 degree ambient. That is comparable to the WRGB II. At SP Group’s $0.32/kWh tariff and an 8 hour photoperiod, monthly power cost runs around $4.80, which is negligible against the lifetime savings against premium fixtures.
Build and Long-Term Reliability
We have run two P Series units in client tanks past the 18-month mark with no failures or measurable PAR drop. The driver brick has not exhibited the buzz some early units reportedly had, and dimming response is smooth from 5 to 100 percent without flicker. The bracket clips show some scuff after a year, but mechanically remain solid.
Comparison Against Chihiros WRGB II
Head-to-head, the WRGB II edges the P600 on app polish, brand support and resale value. The P600 wins on price, often by SGD 60 to 100 at the same length. PAR and spectrum are close enough that visual difference in a planted tank is minimal. Our budget LED guide goes deeper on the cost-per-PAR comparison.
SGD Pricing and Where to Source
Expect $150 to $180 for the P450, $190 to $230 for the P600, and $260 to $310 for the P900. Shopee carries the brand reliably with quick delivery; Reef Wonderland and Y618 stock it for in-person inspection. Carousell second-hand units sit around $90 to $130 for the P600. Be wary of grey-market listings claiming dual-channel “Pro” variants that are simply rebranded older stock.
Where the P Series Falls Short
For high-tech competition scapes pushing 180+ PAR and accurate colour rendering, the Week Aqua spectrum reads slightly less rich than Twinstar E Series or ADA Solar. The app interface is the weakest link, with occasional sync issues and a less polished editor. None of this matters for a working hobbyist’s planted tank, but it is worth knowing if you are documenting builds for competition.
Best Use Cases
Beginner planted builds, second tanks where budget matters, and shop fit-outs where multiple identical fixtures are needed all suit the P Series. We specify it for our budget beginner planted tanks as the default light. For shrimp-heavy scapes we tune the blue channel down to limit algae creep and the result is consistently good.
Verdict
The Week Aqua P Series is the best-value full-spectrum planted LED in Singapore right now, full stop. It does not match Chihiros on polish or Twinstar on colour rendering, but it gives you 90 percent of the performance at 65 to 75 percent of the price. For most hobbyists building their second or third tank, that maths works out clearly in its favour.
