Arcadia Jungle Dawn LED Bar - 15W
A full-spectrum plant light built for mesh-top terrariums. The Arcadia Jungle Dawn LED Bar 15W is a 290 mm plant-growth LED fixture for bioactive and planted vivariums, running a 6200K full-spectrum output with a 120° beam. It mounts on top of a mesh lid or screws directly to a wooden vivarium roof, and pairs with a separate UV-B lamp for the reptiles living underneath it.
Key features
- 6200K full-spectrum LEDs - CRI 85+, with 68% PUR (photosynthetically usable radiation) for genuine plant growth rather than just a bright white light.
- 120° beam angle - spreads light across the footprint rather than a narrow spot.
- 290 mm bar - suited to 30-90 cm wide mesh-top enclosures alongside Arcadia's other Jungle Dawn lengths for wider setups.
- Mesh-top or screw mounting - sits on the mesh lid or fixes to a wooden canopy, with a fittings kit included.
- Integrated on/off switch on the power cable.
- Low running cost - 15W draw keeps it cheap to run over a planted terrarium's lighting hours.

Light output at distance
Arcadia publishes lux and PAR readings at stated distances from the bar. Use this to judge whether a plant on a lower shelf or in the substrate is getting enough light, rather than going on wattage alone.
| Distance from light | Illuminance | PAR |
|---|---|---|
| 100 mm | 34.4 klux | 661 µmol |
| 150 mm | 26.6 klux | 448 µmol |
| 300 mm | 8.9 klux | 146 µmol |
| 375 mm | 6.0 klux | 87 µmol |
| 450 mm | 4.2 klux | 53 µmol |
Low to mid-light terrarium plants (pothos, ferns, mosses, many broadleaf tropicals) do well from 300-450 mm. Higher-light plants sitting close to the canopy see the strongest output nearer 100-150 mm.
Will it fit my enclosure?
The 290 mm bar suits mesh-top or wooden-canopy vivariums from roughly 30 cm up to 90 cm wide - Arcadia sells longer Jungle Dawn bars for wider enclosures rather than expecting one 15W unit to stretch across them. Mount it a minimum of 125 mm above the enclosure top. Because it's IP20 rated, keep it clear of direct misting or splashback in a humid bioactive setup - mount it above the mesh, not inside the humid airspace.
Running costs
At 15W, running the bar for 12 hours a day works out to roughly 66 kWh a year, or around $20 a year at a 30c/kWh tariff. Actual cost depends on your photoperiod and electricity rate.
Suitable for, and not suitable for
Suitable for: live plants, moss and bioactive substrate in terrariums and vivariums, run alongside a separate UV-B or heat lamp for the animals.
Not suitable for: use as the sole light source where a reptile also needs UV-B - this is a plant-growth light, not a UV lamp, and carries no UV-B output. It's also not rated for direct water contact or submersion.
Goes well with
- An Arcadia ProT5 or D3+ UV-B kit, for the reptile living under the same canopy.
- An Arcadia Pro Ceramic Lamp Holder & Bracket, where a separate basking lamp is also needed.
Warranty and delivery
Check current warranty terms with Arcadia at the time of purchase; this is in addition to your rights under the Australian Consumer Law, which apply regardless. Supplied with an Australian mains plug.
Common questions
Will this light grow plants in my terrarium?
Yes - it's a 6200K full-spectrum LED with 68% PUR, built for plant growth rather than general viewing light, and Arcadia publishes PAR figures from 100 mm to 450 mm so you can judge whether it reaches a given shelf or substrate level.
Does it provide UV-B for my reptile?
No. It has no UV-B output. Pair it with a separate Arcadia UV-B lamp such as a ProT5 kit for the animal's UV needs.
Can it get wet?
It's rated IP20, which is not splash or waterproof. Mount it above the mesh top, clear of misting systems and direct humidity.
How do I mount it?
It sits on top of a mesh lid or screws to a wooden vivarium roof, at least 125 mm above the enclosure, using the fittings kit supplied.
What size enclosure does the 15W bar suit?
Roughly 30-90 cm wide mesh-top vivariums. Arcadia makes longer Jungle Dawn bars for wider enclosures.
