On this budget, the most useful purchase is usually a basic flash rather than bulbs. A cheap manual or TTL speedlight can give better results for portraits than household lights, especially if you bounce it off a ceiling or wall for softer light. One answer specifically recommended an inexpensive Yongnuo flash, noting that even manual flash is workable with a few test shots.

If you mainly shoot video, continuous light is more useful, but at this price level you’re mostly looking at DIY or hardware-store solutions: clamp lights with bright CFL bulbs, plus diffusion such as iced acrylic.

To stretch your budget, skip the 5-in-1 reflector and use white poster board or foamcore as a reflector instead. DIY modifiers like a softbox, diffuser, beauty dish, or light tent can also work well for very little money.

So the best starter path is:

1. For still portraits: buy a budget speedlight and bounce it.
2. For video or extra fill: use DIY reflectors and simple continuous lights.
3. Put more money into modifiers and stands later, when your budget grows.
