| Choose if | A solo user with about 42.5 × 48.25 in of floor space who wants full-spectrum heaters running off a standard 120V, 15A outlet. | Two adults with a 20 A outlet and about 60 × 56 in of floor space who'd rather have long warranty coverage than a published price. |
| Main trade-off | There's no published price, labor is covered for 7 years rather than for life, and the 14.6A draw leaves little headroom on a 15A circuit. | You can't compare its cost upfront with listed-price cabins like the Sunlighten Amplify II, labor coverage ends after 7 years indoors, and a return costs 25% plus freight and the original shipping charge. |
