Do these bulbs fit the Hydrofarm JSV4 4-FOOT Jump Start T5 Grow Light System sold on Amazon?

It sure looks like it does....it is 4' long...T5 for sure...and others who bought it bought 4' bulbs. You are a go!

No, it's only a 2-pin G4 replacement. It's a great replacement light but will not fit T5. I have not found one suitable for my T5 lights yet.

They will FIT, but they are designed for electronic ballasts, and the old T12 ballasts will burn them out much quicker if they work at all. Plus you won't save any money on electricity if you keep the old magnetic ballast. Not a good idea to swap them without at least putting in a T8 electronic ballast.

Elizabeth, I just measured the pins on the T0007-25 bulbs. They are 4.0 mm.

Mine came with the T5 bulb. It's a great little light that works really well for plants.

99% sure they will fit, when installing clamp the prongs so the light don't shake and leds work one way if it doesn't work turn the bulb 180 deg.

IT comes with a T5 bulb I don't know if it is standard - it measures 21 1/2" it seems to be the normal T5 for the 2 foot stand

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

I have no way to adequately respond to this question. Bulbs come in standard lengths: 24" or 48". One or the other, just like a regular florescent bulb. T5 bulbs do require a receptical that will accept T5 bulbs; a standard fixture won't do.

I think it would work as long as Hydrofarm didn't use some type of proprietary plug in like they do on their ballasts. The JSV2 also looks like it uses two T5's, were this comes with four; though the base looks wide enough to balance it out. I would get the 2' extenders for two reasons. 1) flexibility with strains and vegetative length 2) The wires used to hang the light are not adjustable and are a good ~12-16". I hope this helps. If you do buy the JSV2 will you please let me know how it goes?Just so you know, I love this 2' four bulb system. It puts out a lot of light and stays fairly cool. I thought about buying the JSV2 as well, but opted for two screw hooks, some chain and a couple s-curves. Take care and good luck :)

Yes, I replaced the T5 low wattage lanscape bulbs with these. They actually fit more snuggly than the T5's which were always losing thier connection in the fixture. Initially thought they were not very bright, but really like them now.

no they are for candelabra sockets. much smaller than typical. look for a g25 or t9 bulb to fit in a normal socket

I'm using a 6 bulb t5 . It fits between the frame rails. It's about the same size.

I bought a 35 watt H.I.D. Kit with size H4 bulbs. Fits perfect. Regular H4 halogen bulbs will fit too. I love this combo. The lenses are glass instead of plastic and the LEDs look great hooked up to the running lights.

Yes they will. My Malibu lights had a T5 bulb and these fit right in there.

It comes with a 24 inch T8 bulb so I would think that what you list above would fit.

T5 are the same size socket as 74 bulbs. If your cluster has 74 bulbs then yes it will fit. FYI: T10 are same socket size as 194 bulbs.
