مصباح كشاف زجاجي BL901-1 مع حامل

The BL901-1 sight glass spotlight with bracket is a separate, battery-powered inspection lamp designed to sit beside a compatible observation window. Its slotted stainless steel bracket lets the installer position the light toward the viewing area without making the lamp part of the window assembly. The 2025 Borlan Fluid catalog calls this a flange spotlight without a flange: the photograph shows the lamp and bracket, not a supplied sight glass, flange, glass or gasket.

When to Choose a Separate Bracket Spotlight

Choose this form when a vessel already has a compatible sight glass and the requirement is to illuminate it from the outside. The bracket can be positioned to suit the available mounting point and viewing direction, subject to the actual vessel geometry. Since the BL901-1 family is battery powered, no permanent external supply cable is shown in this catalog configuration. For a new observation point where the lamp and window should be specified together, compare the BL901-1 integrated flanged sight glass with light.

• Catalog form: separate BL901-1 spotlight with a slotted mounting bracket; flange and sight glass are not part of this catalog item.
• Light and power: the BL901-1 family selection table gives a 3 W, 4.5 V battery-powered reference using three cells. Confirm the ordered lamp and battery supply scope.
• Bracket position: determine the fastener location, clearance and beam direction from the installed window and vessel drawing.
• Inspection role: illumination for visual observation through a separately selected compatible sight glass.

BL901-1 Bracket Spotlight Dimensions

This drawing and single numeric row are from the BL901-1 separate flange spotlight section of Borlan Fluid’s 2025 catalog. All values are in millimeters. The drawing shows labels H, d, d1, L1, L3 and ØD. It also marks L on the lamp body, but the printed numeric row does لا give L; no overall lamp length is inferred here.

Catalog reference only. Bracket, fastener and clearance details should be confirmed for the actual sight glass and vessel.

Battery and Explosion-Proof Documentation

Chinese explosion-proof certificate CLEx24.3249 identifies a BL901-1 sight-light sample rated DC 4.5 V, 3 W, powered by three 1.5 V AAA alkaline cells in series. The certificate marks that tested construction Ex ib IIC T4 Gb / Ex ib IIIC T130°C Db and IP65, and prohibits charging, replacing or disassembling the batteries in a hazardous area. Its scope must be checked against the exact lamp and bracket configuration ordered; it does not automatically establish approval for rechargeable cells, a changed housing or another sight-glass assembly. Ask Borlan Fluid for the current matching certificate when hazardous-area use is specified.

Battery operating time, beam angle, ambient temperature and suitability for a particular site are configuration-dependent. The catalog drawing does not establish these values. Tell us how often the window will be inspected, the installation location and the required documentation so the proposed spotlight can be reviewed before purchase.

الأسئلة الشائعة

Does this product include the sight glass or flange?

No. The catalog labels the BL901-1 flange spotlight without a flange. Specify the observation window and its connection separately, or ask about an integrated flanged assembly.

Can I use rechargeable batteries?

The family catalog mentions rechargeable battery options, but the cited explosion-proof certificate specifically documents three AAA alkaline cells in its tested sample. Do not assume another battery arrangement has the same hazardous-area approval; request the exact approved configuration.

What is the overall lamp length?

The catalog drawing marks L, but its numeric row does not give that value. Request the approved dimensional drawing for your bracket and installation clearance.
