EG25 vs WP40 vs TP40 vs Twin Vent II: Which Smoke Grenade is Right for You?
Published Last updated
Last updated
Every Enola Gaye smoke grenade Shutter Bombs sells solves a different problem. Burn time, vent layout, and ignition type are not interchangeable — and the TP40 and Twin Vent II are not the same product, even though they get mixed up constantly online. This guide compares the full lineup using manufacturer specs and current Shutter Bombs pricing so you can match the right grenade to your shoot, event, or field day.
Quick Picks by Use Case
- Portrait / wedding / senior photos: WP40-D — 60s sustained plume, wire pull, lowest single-can price in the 40mm family.
- One-handed or gloved activation: TP40 — same 60s sustained output, top-pull cap for fast redeploys between takes.
- Gender reveal with the longest cloud time: Gender Reveal WP40 — 90s, discreetly labeled pink or blue so the color stays secret.
- Budget, bulk, or quick bursts: EG25 Micro — ~25s per can, $8 single or a $70 10-pack for teams and group reveals.
- Instant wide burst: Twin Vent II — 25s dual-vent "hero shot" can; densest instant cloud, not a sustained pose window.
- Maximum single-vent burn: WP40 — 90s wire pull, the longest burn in the standard nine-color lineup.

Pro insight
TP40 and Twin Vent II are the two most-confused models online. TP40 = 60 seconds, single vent, top pull. Twin Vent II = 25 seconds, dual vents, wire pull. One gives you a long working window; the other dumps a wide cloud all at once. Different products, different jobs.
EG25 Micro — 25 Seconds, Compact, Best Value
The EG25 Micro is Enola Gaye's smallest format: roughly 25 seconds of smoke per can. It's sold two ways — as a single can for $8 or as a 10-pack for $70 — which makes it both the cheapest way to try colored smoke and the easiest way to arm a whole group. Reach for it when everyone in a team entrance or group reveal needs to hold one, or for quick test frames before you commit a longer-burning grenade to the real shot.
Plan your shot list around the shorter window: 25 seconds is enough for one or two strong poses, not a multi-setup session. For that, step up to a 60-second WP40-D. Read the full EG25 Micro review for a closer look at the starter can.

WP40-D Wire Pull — 60 Seconds, the Primary Pick
The WP40-D is our default recommendation for photography and most outdoor events: about 60 seconds of sustained, directional smoke, wire-pull ignition, all nine colors, and the lowest single-can price in the 40mm family at $12.50. If you're buying one format and want it to cover the widest range of shoots, buy this one.
Sixty seconds is the sweet spot for portraits — long enough to work two or three poses, short enough that you're not babysitting a runaway cloud. Pull the wire ring firmly to the side (never straight up), hold the can by its base, and let the wind carry the plume across your subject. For setup details, see the wire-pull smoke grenade guide.
TP40 Top Pull — Same 60 Seconds, Different Ignition
The TP40 delivers the same ~60-second sustained burn as the WP40-D from a single vent. The one real difference is ignition: you pull the cap straight up instead of pulling a wire ring to the side. That matters more than it sounds. Photographers wearing gloves, anyone juggling a remote shutter, or shooters who want a clean one-handed activation between takes tend to prefer the top-pull cap.
It is not a dual-vent burst grenade — that's the Twin Vent II. The TP40 is simply a WP40-D with a friendlier trigger. If you're torn, read the dedicated wire pull vs top pull guide.
Twin Vent II — 25 Seconds, Dual-Vent Burst
The Twin Vent II vents from both ends at once, building a wide, dense cloud in the opening seconds of activation. Enola Gaye rates it at about 25 seconds of total burn — a short, dramatic burst, not a 60-second posing window. Use it when you want maximum spread instantly: sports entrances, dramatic single stills, music-video hits, or airsoft cover where you need a wall now.
Don't compare it to the TP40 on burn time; they're not competing for the same job. Compare it to the EG25 on brevity — same ~25-second window, but with far more lateral spread because the charge exits two vents simultaneously. At $14.50 it's the priciest single in the standard lineup, and it earns that as the "hero shot" can.

WP40 Wire Pull — 90 Seconds, Longest Standard Burn
The classic WP40 runs about 90 seconds on a single wire-pull vent — the longest burn in the standard nine-color lineup. It's the pick for photographers who need extended working time across multiple setups, or for events where you want the smoke to linger. Same side-pull ignition and same nine colors as the WP40-D, just a longer charge.
If you specifically want a 90-second burn in pink or blue, the Gender Reveal WP40 runs on the same 90-second platform with discreet labels.
Gender Reveal WP40 — 90 Seconds, Pink or Blue
Purpose-built for reveals: a 90-second burn on the WP40 platform, an oversized cloud, and pink or blue smoke with discreet labels so whoever's holding the can can't spoil the surprise. It's the premium pick when the moment matters more than per-can cost, at $18.99.

How to Choose: A Decision Checklist
Work down this list and the right model usually falls out in under a minute:
- How long do you need the smoke? 25s for a single dramatic frame (EG25 or Twin Vent II); 60s for a normal portrait session (WP40-D or TP40); 90s for multiple setups or reveals (WP40 or Gender Reveal WP40).
- One cloud or a wide wall? A single directional plume reads cleaner on portraits (WP40-D, TP40, WP40). A wide instant burst sells entrances and action stills (Twin Vent II).
- Gloves or one-handed activation? Choose the top-pull TP40; otherwise the wire-pull WP40-D saves you $0.75 a can.
- Buying in volume? The EG25 10-pack ($70) is the cheapest per-can route for teams and group shots.
- Is the color a secret? Use the discreetly labeled Gender Reveal WP40 so the holder never sees pink or blue before the pull.
Tip
Buying for one shoot? Grab two burn lengths — a couple of 25-second cans for the opening "hit" plus a 60-second WP40-D or two for the actual portraits. That way a misfire or a gust never costs you the shot. Build a mix on the bundle builder.
Frequently Asked Questions
Is the TP40 the same as the Twin Vent II?
No. The TP40 is a ~60-second, single-vent, top-pull grenade built for sustained portrait smoke. The Twin Vent II is a ~25-second, dual-vent, wire-pull burst that dumps a wide cloud all at once. They're a similar canister size, but they serve completely different timing and cloud-shape roles.
Which smoke grenade has the longest burn time?
The WP40 and the Gender Reveal WP40 both run about 90 seconds — the longest in the lineup. Among the standard nine-color singles, the WP40-D and TP40 each run about 60 seconds, and the EG25 Micro and Twin Vent II run about 25.
Should I choose the WP40-D or the TP40 for photography?
Same ~60-second output, so pick on ignition. Choose the wire-pull WP40-D for the familiar side pull at the lowest price ($12.50). Choose the top-pull TP40 ($13.25) if gloves or fast one-handed activation between takes matter more. See the wire vs top pull guide for the full breakdown.
When should I use the Twin Vent II instead of the WP40-D?
Use the Twin Vent II when you need an instant wide wall of smoke for a single moment — a sports entrance, a dramatic still, an airsoft push. Use the WP40-D when you need ~60 seconds to work multiple poses. The Twin Vent II is 25 seconds across two vents; the WP40-D is 60 seconds from one directional vent.
Is the EG25 sold as a single can?
Yes. The EG25 Micro is available as a single can for $8.00 or as a 10-pack for $70.00. Each can burns about 25 seconds per Enola Gaye specs.
Do all the models come in the same colors?
The EG25, WP40, WP40-D, TP40, and Twin Vent II all come in the full nine-color range: black, blue, green, orange, pink, purple, red, white, and yellow. The Gender Reveal WP40 is pink or blue only, with discreet labels to keep the color secret. See the smoke bomb color guide to match colors to your scene.
