This is a specific conversation about Bearded dragon lighting — UVB and basking done right — ask about yours and get one honest answer for your exact situation.

Bad lighting is the single most common husbandry mistake with bearded dragons — incorrect UVB or basking temperatures lead to metabolic bone disease and chronic illness that many owners don't spot until real damage is done. Getting photoperiod right is a smart, proactive move, especially at six months when your dragon is still growing fast. To point you in the right direction: what size enclosure are you working with, what UVB and basking bulbs are you currently running (brand and wattage), and how old is the dragon exactly?
He's just turned six months. I've got a 4x2x2 ft enclosure, using an Arcadia T5 HO 12% UVB and a 100w basking halogen. I just want to make sure I'm automating the day-night cycle properly rather than relying on myself to remember to switch things off.

That's a solid setup — Arcadia T5 12% is exactly right for a dragon that size, and a 100w halogen in a 4x2x2 should give you a good basking spot. Your instinct to automate is spot on. Inconsistent photoperiods disrupt sleep, appetite, and digestion in bearded dragons, and at six months you want everything dialled in while he's still developing. What you need is a reliable dual-channel timer so you can run the UVB and basking lamp on the same schedule without them being tied to the same socket — are you currently running them off the same plug, or separately?
They're on separate plugs at the moment, which is part of why I keep forgetting. I'd love something that controls both independently but is easy to programme.

Perfect — then what you want is the Inkbird IBS-M1 WiFi smart power strip. It gives you four individually controlled outlets you can schedule through an app on your phone, with repeat daily schedules that take about two minutes to set up. You can put the UVB on one outlet and the basking lamp on another, set your 14-hour photoperiod for summer and drop it to 10-11 hours in winter if you want to encourage a natural seasonal rhythm — which is good practice even for captive dragons. The app is clear, the hardware is reliable, and once it's set you genuinely never think about it again. It's available on Amazon UK for around £30-35.
That sounds ideal. Should the UVB and basking lamp be on exactly the same schedule, or should one come on before the other?

Good question — run the UVB on the same hours as the basking lamp, but you can have the basking lamp come on 15-30 minutes after the UVB if you want to mimic a gradual morning warm-up. It's not essential, but dragons do seem more settled with a slight ramp rather than everything switching on hard at once. More importantly, make sure both go off at the same time in the evening. No UV or heat after lights out — the enclosure should drop to ambient room temperature overnight, which for a six-month-old should sit comfortably between 18-22°C. If your room goes colder than that in winter, a ceramic heat emitter on a thermostat is worth adding, but that's a separate conversation once you've got the timer sorted.
This has been really helpful. I'll grab the Inkbird strip. One last thing — how long should the photoperiod be at this time of year?

For a six-month-old juvenile in active growth, keep him on 13-14 hours of light through spring and summer, then gradually wind it back to 10-11 hours through autumn and winter — drop it by about 30 minutes every few weeks rather than changing it abruptly. Juveniles don't fully brumate like adults, but a slightly shorter winter photoperiod keeps their circadian rhythm healthy and matches what they'd experience naturally in central Australia. Set it, forget it, and check the schedule again when the clocks change. You're clearly on top of your husbandry — he's lucky.
