Sourcing Replacement Lighting

[Juggler75]

So the bulb in my Aqua One 620 shrimp tank started blinking today (stays on for 5-10 mins then blinks for 10 mins then on again). This happened about 6 weeks ago with the other bulb and I replaced it with a spare I had and fixed the problem so I think it must just need a new bulb.

I have managed to source these as a possible replacement but cannot find a cheaper non aquarium bulb supplier as I don't know what I'm looking for in a google search (Bulbs are old and have no writing on)

Any help would be appreciated.

Thanks in advance

the bulbs are a funny size, i haven't found any non-aquarium sources but you could try an electrical wholesaler.
