Nikon SB-910 Vs. Nikon SB-900: Speedlight Overheat Test by Cary Jordan (Web | Flickr | Personal FB page |The Jordan Collective’s FB Page | Twitter)

When the Nikon SB-910 Speedlight was announced, it brought-forth the promise of fixing the Nikon SB-900’s one serious flaw: Overheating issues. The SB-900 is a great flashgun, but for some photographers in the event and wedding photography genres, the SB-900 just couldn’t keep up with a fast-paced shooting environment, without overheating. Enter the SB-910 Speedlight: Nikon promised the overheating issues of the SB-900 are gone in this new iteration, but is it really a thing of the past?

Hit the link to watch the video comparison of the SB-900 against its predecessor, the SB-910. Which one will overheat first at full-power?

Conclusions: The Nikon SB-910 lowers power once it reaches high operating temps. This keeps the speedlight from overheating, but slightly affects overall performance. The SB-900 shuts-down instead of lowering power once it reaches high operating temps. This renders the SB-900 useless until it cools. Using an external battery pack greatly reduces operating temps in the SB-900. The user can also disable over-heat protection in the SB-900, but at the risk of damaging the flashgun.

  • Each flashgun was set on manual mode 1/1 (full-power), ISO-100, ƒ/5.6, 24mm, identical flash pattern
  • Fully-charged Rayovac Platinum 2100mAh NiMH rechargeable AA batteries were used in both flashguns
  • Each flashgun was triggered manually, at the same exact time
  • Video was filmed on a NIkon D7000 (1080/24p)
