No, this is for 3 or 4 T8 bulbs. You want the GE Lighting 23671GE Lighting 23671 GE232-120-N 120-Volt ProLine Electronic Linear Fluorescent T8 Standard Instant Start Ballast 2 or 1 F32T8 Lamps

I used them in one, but it depends how big the globe is and the position of the sockets inside. These bulbs measure 4" from the bottom of the socket, or 3-1/2" from the base. Hope that helps.

I've only ever used a recessed lighting fixture in these, not a bulb. However the recommended bulb for these are BR30's, I'm not sure if a BR40 will fit.

As long as the stock bulb size is 6418, which I believe it is, they will work. You might just want to double check.

Probably not, I had a hard time putting them into anything that had any sort of "socket extension" beyond the socket itself. Tried on many different lamps and light sockets, but the best places to use them were generic sockets, think the work lamps from home depot, things like that.

Yes. T9 is the size. Any T9 bulb will work. The 2700K that you state is the white-ness / yellow-ness of the light. The 32W that you state means that your existing bulb consumes 32 Watts of electricity. This product consumes just about the same at 30 Watts, so it will work fine. You wouldn't want to overload your existing light fixture with too many Watts, so equal Wattage or a little lower will be fine.

No. This a 2 pack of cool white 12", 8 watt bulbs. For a (different brand) 2 pack of warm white 12", 8 watt bulbs, use Thin-Lite F8T5/WW/Twin.

I am not to well versed in this matter, I do know though that the bulbs come with two different connections and either can be used. Just use the one that fits and leave the other to dangle. Hope this helps.

They should. Any socket that accepts that size bulb.the only problem is that they dont dim.their either off or all the way on.but they look good

FYI The bulb type tells you the answer. The 40 in BR40 is 40/8. all bulb types are the same. A19 is 19/8, etc. I don;t know why they chose that method, but all bulb diameters are in eights of an inch/

If it looks like this, same dimemsions and four pin connection, it should work.I have only found one bulb with these dimemsions and connection.

it depends what kind of fixture is, if its a t5 fixture that will take t5 bulbs, t8 t8 bulbs, and so on and so forth

if 5 regular 40w bulbs worked for you then this would be fine. these bulbs are at least as bright as a regular 40w gmail candelabra bulb

I guess it would depend on the width of the individual bulb. As you can see the sockets extend away from each other to offer more side room so that the bulbs don't touch. The bulbs I use are about 3 1/2 inches across and they are not even close to touching one another.

They worked with T10 base LED lamps used for landscape lighting. I did not try any other bulbs.

Any T5 bulb that will fit can be used; the two-pin ends are universal. That said, it uses an odd length that I think only this brand makes. So you'll have to check Zoo Med's bulb selection and see if they make what you need. I suspect they do as they are known for their reptile habitats as well.

I would have to say no. It is designed for larger bulbs than that and would not fit.
