Kelvin Tan –
Took the SL4 eLED (L1) on a night dive at Pulau Hantu and it performed brilliantly! The beam is strong and the grip is comfortable, even with my gloves on. Battery life lasted the whole dive too.

Aishah Rahman –
Is the SL4 eLED (L1) available with rechargeable batteries included, or do I need to get them separately?
Junhao Lo –
Hi Aishah, the SL4 eLED (L1) is supplied without batteries, so you’ll need to purchase either alkaline or NiMH rechargeable C-cell batteries separately. Please let us know if you need any recommendations.
Anand Singh –
Solid torch, but I wish the on/off mechanism was a bit easier to operate with really thick gloves. Otherwise, brightness and build quality are both very good.
Junhao Lo –
