Bioscape Tropic Nano 40L Aquarium (BIS135)
Part no.
BIS145
Bioscape LED Light BIS135
A genuine replacement light and lid unit for the Bioscape Tropic Nano 40L aquarium. If the integrated LED on your 40L Tropic Nano kit (aquarium model BIS135) has failed, cracked, or was missing from a second-hand tank, this part replaces just the light – not the whole aquarium.
Key features
- Sized to the 40L Tropic Nano's footprint – matches the external footprint of the Bioscape Tropic Nano 40L aquarium (48 x 44cm), so it seats the same way the original light and lid did.
- Genuine Bioscape part – the same unit supplied with new 40L Tropic Nano kits.
- Mid-size step in the Tropic Nano range – sits between the 24L and 61L light units; check your tank's model number before ordering, since the three sizes aren't interchangeable.

Common questions
How do I check which size my tank is before ordering?
Measure the external footprint of your aquarium – the 40L Tropic Nano measures roughly 48 x 44cm. If your tank is smaller or larger than that, you likely have the 24L (BIS134) or 61L (BIS136) instead.
Does this include a new transformer?
Bioscape doesn't specify this separately for the light unit – check your existing transformer for damage before ordering, and contact Bioscape if you need this confirmed.
Can I use this light on a different brand's 40L tank?
No – it's built to the exact footprint and fitting of the Bioscape Tropic Nano 40L and isn't designed as a universal fit.
