Does anyone know what lightbulbs go in this?

Hello!
I just bought a secondhand 10 gallon, which came with a hood and lights among other things. Unfortunately, both bulbs are burned out. Does anyone know what lights these are/what can fit in the hood? Thanks!

They look like metal halide globes but that would be overkill for a 10 gallon tank.
Do the globes have anything written on them?

Can you clean the globe and take more pictures so I can see the filament inside the globes?

The bottom of the bulb (the metal bit) has 120V15W on it

These are just normal incandescent bulbs screw the old ones out and screw the new ones in.

Remember when screwing

Righty tighty, lefty loosie

I’ve never seen this shape before though, are they just shaped different?

You can get an led bulb exactly that size. I bought one for a very old desk lamp that had that exact bulb.
Here's one but there are others:

this one is 2700K though which is warm white, not daylight type

They are made like that to push the light out and to be low profile to fit in the likes of a light hood. Go LED if you can.

Awesome, thanks guys !

Be aware, 2700K bulb is not great for growing plants.

This bulb would be better for plants...it's 5000K

Sorry I missed the 27k part of this. I agree 27k is not great for plants

Like the others said, just a normal incandescent globe that is long instead of round. Look for LED or compact fluorescent with a 6500K (K is for Kelvin) rating.

Most globes come in warm white with a 2500-4000K rating, and a cool white with a 5500-6500K rating. Get the cool white if you can.

When i built my ague lid with CRI90 LED light strips I used 3000K. Worked fine but plants were growing about 4 times tall than normal. An indication of now enough red. I then added some 660nm red strips. So I am probably between 2700 and 3000. 27K willl work fine.

Plants need both red and blue but IF you have mostly blue the plants will think they are being shaded by other plants and will put all their growth in growing taller than normal. With more red they tend to stay at their normal default height.

Incandecent lights put out more red at high K levels. mainly because high K bulbs run at higher filament temperatures to produce more blue. Hi K LED will give you a lot of blue but little red. 2700K will give you more red and some blue.

I actually have something similar that came with my tank collection I purchased used.

Pic coming ...

those appear to be standard bulb bases, forget what they’re called. My 10 G tank hood for the betta is the only one that uses such bulbs. I have a pair of low watt LEDS in there now. Cheap & available every where
