For $4+ I don’t see why not, if you’re only going for intro into UV. You get a reasonable host at least, and the emitter should still demonstrate some UV characteristics.
A good option IMO would be to get those new chinese 365nm emitter, they’re going ebay for around $10 for 2, and mod it into any of your existing light. Our member djozz had tested it and confirmed it does give off 365nm, with the drawback only being lower output vs expensive emitters.
