Frequently Asked Questions - Grantham XL USB Up & Down Solar Motion Light

Hello,

Bracket 90mm width x 130mm length

in dim mode it is around half the brightness, then when triggered returns to full brightness for the duraction of the activation, then back down to half. We would not recommend the first mode for Winter. 

Hello,

This light is 120 lumens. 

Hi, the wattage of the panel is 0.76w

it is not advisable to run this completely from USB. You can always give this a much needed boost but not fully run this from the USB cable. 

Please see below there are two different lighting mode that you can use. 

Mode 1: After dusk, the light will remain on at a lower brightness until motion is detected to activate full brightness for 15 seconds after the motion has finished and it will return back to the lower brightness setting.

Mode 2:The light will remain OFF until motion is detected to activate full brightness for 15 seconds after the motion has finished (best for winter)

The light will need to be taken down once installed if you wish to USB charge it. I would recommend fully charging via USB initially until fully charge (should turn green) then in Summer you can have it on the Mode 1 and you should not need to top it up via USB, perhaps when the days get shorter give it another additional boost, then place the light on the Mode 2, again you should then not need to top it up.  

No, we do have the non motion version  which is dusk till dawn. 

The light will need to be taken down for every USB charge. However if you give this a boost iwth the USB you can always leave these on power saving in the winter, this will help it run for longer in winter and lessen the need for the USB charging. In summer, depending on location you should not need to top this up. 

Hi,  

It's very easy, the USB charger is behind a cap with one screw sealing it shut. On the power-saving mode, you may not have to recharge the light at all, depending on location. If the light receives enough light exposure, you should not have to recharge often at all, it is a feature we've included "just in case".

Hi Chris, 

The grantham light is not USB chargeable, but the Grantham XL is.

Hi Keith, 
After detecting motion the light will be on full brightness for up to 15 seconds.

The space between the fixing holes is 35 mm. At the moment we have Black Friday deals going on, if you are quick you can grab a bargain!

There are two modes

Mode 1: After dusk, the light will remain on at a lower brightness until motion is detected to activate full brightness for 15seconds after the motion has finished and it will return back to the lower brightness setting.

Mode 2:The light will remain OFF until motion is detected to activate full brightness for 15 seconds after the motion has fnished [best for winter]

So in both cases  the light will stay on brightly for 15 seconds after motion, but there is the option in having the light on constantly in a lower brightness mode. 

The internal battery has the average lifespan of 2 to 3 years, however it is replaceable, and therefore the product can run for a very long time.
